We have been fed, ad nauseum, that Cannabis is just a plant and relatively harmless, right? If you say it loud and long enough, you might believe it? We were told by the consensus manufacturing #420 activists and their propogandist promotors, the evidence ignoring media, that if we legalize this stuff ALL will be well – on every front!
No more crime! Health will increase! Taxes and surplus revenue will be raised, well, so the cornucopian pronouncements went. Well, a chaotic conundrum has inevitably arisen. All promises have not only failed, but greater harms are being done to even more of our community, with the permission modelling pushing the drug onto a now ill-informed culture and clueless Gen Next.
Here you will find an ever growing list of data that is but a fraction of the evidence-based scientific research that reveals the social, mental, health, genetic, environment and community harms of this ‘harmless plant!’ If facts and evidence matter in making informed best-practice decisions, then this is your space!
Public Health Significance—Dual use of alcohol and cannabis appears to be associated with adverse behavioral and psychological consequences and is a rapidly growing public health concern. This study suggests dual users have greater demand for alcohol, steeply discount delayed alcoholic drinks, and are at higher risk for alcohol use disorder than individuals who consume alcohol but do not consume cannabis.
The reinforcer pathologies model proposes 2 behavioral economic constructs interact in addiction: operant demand and delay discounting. These constructs manifest as behavioral markers of addiction in the form of excessive reinforcer value and strong preference for immediate access and consumption of this reinforcer despite suboptimal long-term outcomes. The first aim of this investigation was to identify the degree to which delay discounting (of money and alcohol) and demand for alcohol differ between college student drinkers (N = 185) who do and do not co-use cannabis. As a second aim, we sought to replicate the 2-factor solution for alcohol and cannabis demand within a college sample. Results suggest dual users have significantly stronger Persistence and Amplitude for alcohol, demonstrate steeper delay discounting of alcoholic drinks, and are at greater risk for alcohol use disorder than individuals who drink yet do not use cannabis. These results provide further support for the reinforcer pathologies model and contribute to the literature on dual-substance use in the college populationNude, G. P., Reed, D. D., Thornton, T. J., & Amlung, M. (2021). Dual use of alcohol and cannabis among college students: A reinforcer pathologies approach.

After a strong, sustained and successful anti-cannabis demand reduction campaign in the late 80’s and early 90’s, cannabis use was declining from a then historic high, but the N.O.R.M.L’s push to use ‘medicinal marijuana’ in the mid 1990’ as a trojan horse to get declining youth use back up, has seen that strategy work, as the following tragically reveals.
Key MTF findings on college students’ marijuana use in 2020 and recent trends are:
In 2020, annual prevalence of marijuana use reached a historic high since the early 1980s, at 44%.
The five year trend from 2015 to 2020 showed a significant 6% jump in the annual prevalence of marijuana use.
Daily marijuana use increased to 7.9% a new all-time high over the past four decades.
Over one-in-twelve college students use marijuana on a daily or near daily basis.
30 day marijuana vaping doubled between 2017 to 2019 from 5.2% to 14%. It slightly declined in 2020 to 12%.
44% Annual prevalence of marijuana use among U.S. college students
The U.S. Monitoring the Future (MTF) report for 2020 found, among college students annual prevalence of marijuana use reached a historic high since the early 1980s, at 44%.
Abstract: Up to 20% of pregnant women ages 18–24 consume cannabis during pregnancy. Moreover, clinical studies indicate that cannabis consumption during pregnancy leads to fetal growth restriction (FGR), which is associated with an increased risk of obesity, type II diabetes (T2D), and cardiovascular disease in the offspring. This is of great concern considering that the concentration of D9- tetrahydrocannabinol (D9-THC), a major psychoactive component of cannabis, has doubled over the last decade and can readily cross the placenta and enter fetal circulation, with the potential to negatively impact fetal development via the endocannabinoid (eCB) system. Cannabis exposure in utero could also lead to FGR via placental insufficiency. In this review, we aim to examine current pre-clinical and clinical findings on the direct effects of exposure to cannabis and its constituents on fetal development as well as indirect effects, namely placental insufficiency, on postnatal metabolic diseases, (International Journal of Molecular Sciences)

Denver Health’s substance treatment program sees roughly 500 youths each year for substance abuse, and Thurstone says 95 percent of the referrals he gets are for marijuana, which, despite popular opinion, has been proven to be addictive. Concentrates, with their higher THC levels, may be even more so. But it’s not just the standard trappings of dependence that are worrisome to health care professionals; it’s also that they’re observing a correlation between cannabis concentrates and mental...

Its association with other substance use and...
The genotoxicity of Cannabis has long been suspected, even acknowledged, be it only in part. Research over the last 5 to 10 years has confirmed the case. Much of this important research has been ‘buried’ in the deluge of ‘hopeful’ and even spectacular claims of the potential therapeutic capacity of cannabis. Claims and promises that have persisted for well over 20 years, yet with little to nothing to show for it. However, the harms associated with the use of this now heavily engineered...

ABSTRACT Background and Aims The idea that cannabis is a ‘gateway drug’ to more harmful substances such as opioids is highly controversial, yet has substantially impacted policy, education and how we conceptualize substance use. Given a rise in access to cannabis products and opioid-related harm, the current study aimed to conduct the first systematic review and meta-analysis on the likelihood of transitioning from cannabis use to subsequent first-time opioid use, opioid use disorders (OUD),...
July 11, 2021, BOULDER, Colo. — One day in fall 2018, Bo Gribbon began to vomit and couldn’t stop. He threw up multiple times an hour from morning to night before his mother drove him to the hospital near their home here. “It felt like Edwards Scissorhands was trying to grab my intestines and pull them out,” said Gribbon, then 17. Over the next nine months, Gribbon went to the emergency room 11 times for the same problem: severe vomiting and screaming at the same time that lasted for hours....
Cannabis and cannabinoids are implicated in multiple genotoxic, epigenotoxic and chromosomal-toxic mechanisms and interact with several morphogenic pathways, likely underpinning previous reports of links between cannabis and congenital anomalies and heritable tumours. However, the effects of cannabinoid genotoxicity have not been assessed on whole populations and formal consideration of effects as a broadly acting genotoxin remain unexplored.

Combined exposure to even low doses of alcohol with THC, HU-210, or CP 55,940 caused a greater incidence of birth defects, particularly of the eyes, than did either treatment alone. Consistent with the hypothesis that these defects are caused by deficient Shh, we found that CBs reduced Shh signaling by inhibiting Smoothened (Smo), while Shh mRNA or a CB1 receptor antagonist attenuated CB-induced birth defects. Proximity ligation experiments identified novel CB1-Smo heteromers, suggesting...

Is it inevitable that legalization of recreational cannabis will result in more dependence and psychosis? In theory, it is possible to legalize cannabis in ways that do not increase potency and prevalence of use but, so far, experience with commercialization in North America is not encouraging. Governments that decide to legalize cannabis should use some of the tax revenue to monitor cannabis price, consumption, and potency levels and to carefully evaluate the long term repercussions for...
Date: September 15, 2020 Source: University of Cambridge Summary: Migrants arrested for tending plants in the flats, houses and attics where cannabis is grown in bulk are often victims of trafficking and 'debt bondage' - yet many are not recognized as such by police, according to a new study While growers -- often Vietnamese nationals -- are not always imprisoned within farms, many work under threat of extreme violence towards themselves or family back home, with little in the way of language...

This study found: Children’s risk of marijuana and alcohol use and attitudes toward marijuana were influenced by their parents’ marijuana use pattern over time. Children whose parents used marijuana primarily during adolescence/early adulthood and those whose parents continued to use marijuana from adolescence through adulthood were at highest risk. When parents use drugs such as marijuana, their children may also be affected. Numerous studies have shown that current parental marijuana use...
Published July 6, 2020 Research Article https://doi.org/10.1177/1073110520935338 Abstract: Cannabis use in some individuals can meaningfully introduce de novo risk for the initiation of opioid use and development of opioid use disorder. These risks may be particularly high during adolescence when cannabis use may disrupt critical periods of neurodevelopment. Current research studying the combination of genetic and environmental factors involved in substance use disorders is poorly understood....
04 July 2020 Background and Aims: Cannabis use disorder (CUD) is frequent in adolescence and often goes into remission towards adulthood.

Participants: 5987 Swiss men assessed longitudinally at the mean ages of 20, 21.5 and 25 years old. Measurements: Latent CUDS in the last 12 months was measured at each wave with the Cannabis Use...
Brain changes from using THC too frequently cause withdrawal and craving. Cannabis causes two distinct changes in brain chemistry, physiology, and function that combine to create dependence. Its main psychoactive ingredient, THC, reduces the normal number of natural cannabinoid receptors, a process called downregulation. THC also alters reward circuitry, bending motivation toward continued cannabis use. For complete article
Compared to babies of mothers who didn’t use cannabis before or during pregnancy, infants of those who still used it at 15 weeks had a smaller birth weight, head circumference and length. They were also born at an earlier gestational age. This is cause for concern as these outcomes are strongly linked to future child health and development. We saw bigger differences in these neonatal outcomes for women who used cannabis more than once a week than for those who used it less often. We also found...
Rapper Stormzy, whose real name is Michael Omari, says he has stopped smoking marijuana, after realising the drug was harming his mental health. And because of who he is, his message is likely to reach a lot of people who urgently need to hear it. He said: “I have suffered with mental health problems for the past few years… When I used to feel depressed, I would lock myself away and smoke weed and I would just get worse and worse and worse.” Read More

May 2020 Cannabis is harmful to the lungs, but in a different way to tobacco, causing significant respiratory symptoms such as bronchitis with evidence to suggest it can result in destructive lung disease – sometimes referred to as ‘bong lung’ – in heavy cannabis users. These are the key findings from a review of research on the effects of smoking cannabis on the lungs undertaken by respiratory specialists, Professor Bob Hancox, from the University of Otago’s Department of Preventive and...
Abstract - Objective: Alcohol and cannabis misuse are related to impaired cognition. When inferring causality, four nonexclusive theoretical models can account for this association: 1) a common underlying vulnerability model; 2) a neuroplasticity model in which impairment is concurrent with changes in substance use but temporary because of neuroplastic brain processes that restore function; 3) a neurotoxicity model of long-term impairment consequential to substance use; and 4) a developmental...
by National Drug and Alcohol Research Centre In the first Australian study of its kind, 559 cannabis-related deaths identified between 2000 and 2018 have been examined by researchers at the National Drug and Alcohol Research Centre (NDARC), UNSW Sydney. The leading cause of death was accidental injury (30 percent), followed by suicide (25 percent), and polysubstance toxicity (17 percent). Lead author, Ms Emma Zahra said motor vehicle accidents were the leading cause of accidental injury deaths...
Abstract Cannabis is the third most used psychoactive substance worldwide. The legal status of cannabis is changing in many Western countries, while we have very limited knowledge of the public health impact of cannabis-related harms. There is a need for a summary of the evidence of harms and risks attributed to cannabis use, in order to inform the definition of cannabis risky use. We have conducted a systematic review of systematic reviews, aiming to define cannabis- related harms. We...
New research identifies the possible frequency and severity of a broad range of adverse reactions to cannabis use. A study featuring in the Journal of Cannabis Research identifies the possible frequency and severity of a range of acute adverse reactions to cannabis use. The researchers also investigate factors that might make a person more susceptible to these adverse reactions. The team was specifically interested in acute adverse reactions, in which negative side effects happen for a short...
JAMA Netw Open. 2020;3(4):e202370. doi:10.1001/jamanetworkopen.2020.2370 Findings In this meta-analysis of observational studies including 23 518 participants, the prevalence of cannabis withdrawal syndrome was found to be 47%. Factors that were associated with higher cannabis withdrawal syndrome were clinical settings (particularly inpatient and outpatient vs population settings), concurrent tobacco or other substance use, and daily cannabis use. Meaning Cannabis withdrawal syndrome appears...
A recent study in which rats could self-administer cannabis vapor may provide a useful research model for humans. The study’s most significant finding was that the ingestion of cannabis resulted in drug-seeking behavior not unlike that common in human users of cannabis. Another significant observation describes some familiar behavior the rats exhibited after receiving the cannabis vapor. The rats consumed more food while under the influence, a phenomenon reminiscent of human “munchies,” and...
Female eggs exposed to THC, the psychoactive ingredient in marijuana, have an impaired ability to produce viable embryos, and are significantly less likely to result in a viable pregnancy, according to an animal study accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting… The eggs' developmental rates and gene expression were measured. The researchers evaluated the ability of embryos to reach critical stages of development at specific time points. With higher...

First published:20 February 2020 Abstract - Findings: the initiation of recreational cannabis commercialization was associated with 5.06–5.80 more exposures per 1 000 000 population per quarter (67–77% increase relative to the pre‐legalization average), depending on the composition of comparison states. The increase associated with commercialization was higher among minors than adults (7.97–9.53 versus 3.83–4.21 more exposures), higher among males than females (6.16–7.56 versus 3.76–3.91 more...
The study finds that marijuana commercialization was associated with a 67-77% increase in marijuana exposure calls to poison control centers, with a dramatic rise in exposures among those below the age of 21 . According to the study, had all 50 states and DC commercialized marijuana in 2017, the total number of exposures nationwide would have risen by more than 60%. Also according to the study, marijuana commercialization increased the availability and accessibility of marijuana among minors....
Abstract – Background: E-cigarettes are battery-operated devices that heat a liquid and deliver an aerosolized product to the user. Pulmonary illnesses related to e-cigarette use have been reported, but no large series has been described. In July 2019, the Wisconsin Department of Health Services and the Illinois Department of Public Health received reports of lung injury associated with the use of e-cigarettes (also called vaping) and launched a coordinated public health investigation....
Guillermo, a 19-year-old Chicagoan, said the first time he got stoned “felt like I was a piece of butter melting on a stack of pancakes.” But the rapture faded quickly, and smoking weed soon became a joyless reflex akin to brushing his teeth in the morning, he said. Potent marijuana frequently put him into hangoverlike “kush comas,” he said, and sapped his motivation and alertness so thoroughly that his mother threatened to put him into a mental hospital. “I was just stoned all the time,” he...
Journal of Neuroscience 6 March 2019, 39 (10) 1817-1827; DOI: https://doi.org/10.1523/JNEUROSCI.3375-17.2018 Abstract: Rates of cannabis use among adolescents are high, and are increasing concurrent with changes in the legal status of marijuana and societal attitudes regarding its use. Recreational cannabis use is understudied, especially in the adolescent period when neural maturation may make users particularly vulnerable to the effects of Δ-9-tetrahydrocannabinol (THC) on brain structure....
Depression, anxiety, and trauma diagnoses and symptoms were associated with higher odds of cannabis use among pregnant women in California.

QUESTION: What do these deadly poisons have in common: arsenic, radium, mercury, thallium, cyanide? ANSWER: At one time they were all considered by physicians and the public as useful medications and/or healthy supplements. They were taken in a wide variety of lotions, potions, notions, tinctures, tonics, and pills. These poisons were recommended, sold, and prescribed freely by physicians.1 It took thousands of deaths and many decades before the harmful nature of these substances was perceived...
CONCLUSIONS AND RELEVANCE In this cross-sectional study, parental marijuana use was associated with increased risk of substance use among adolescent and young adult offspring living in the same household.

Highlights We estimate that >2 million U.S. adults who have reported ever using marijuana have cardiovascular disease. Observational studies have suggested an association between marijuana use and a range of cardiovascular risks. Marijuana is becoming increasingly potent, and smoking marijuana carries many of the same cardiovascular health hazards as smoking tobacco. Few randomized clinical trials have been conducted or are planned to explore the effects of marijuana on cardiovascular risk....
January 16, 2020 People who use cannabis every day account for more than 80 per cent of the total amount of the drug consumed in Australia, a University of Queensland study has discovered. The finding suggests there are serious implications for a small group of people if there is a move to decriminalise or fully legalise the drug. UQ researchers examined data from the National Drug Strategy Household Survey between 2007 and 2016. A UQ study has found a small proportion of daily cannabis users...

Colorado, Washington, Nevada, and Massachusetts Post Increases in Youth Use Over Previous Year (Alexandria, VA) - Today, state-level data from the National Survey on Drug Use and Health, the most authoritative study on drug use conducted by the Substance Abuse and Mental Health Administration (SAMHSA), finds that marijuana use in "legal" states among youth, young adults, and the general population continued its multi-year upward trend in several categories. Additionally, use rates in "legal"...
This early study isn't conclusive, but its findings could have grave implications. Sports leagues , state legislators , and universities are changing the way they treat and punish marijuana use largely because the drug is increasingly perceived as harmless. But preliminary research suggests cannabis may have a dangerous side effect on one critical organ: the heart. The new study , which evaluated the health of 3,407 people in the United Kingdom, suggests a link between regularly using...
As is known cannabis causes a dramatic increase in genetic junk by chromothripsis and other mechanisms. And is known to be linked with deformed chromosomes… Including small circular chromosomes. Such small circular DNA fragments have long been known to be detectable in the serum of cancer patient’s circulating blood. Now these small circular extracellular DNA fragments have been shown to be linked with cancer because they have lots of oncogenes on them, and because they lack normal chromatin...

A 2014 study in Forensic Science International reported two cases of sudden death that doctors linked to health complications possibly worsened by marijuana use. The report indicated that before these deaths, the researchers were not aware of any other deaths related to marijuana use alone. It is important to note that only after excluding all other causes of death did the report assume the young men experienced fatal cardiovascular events brought on by cannabis. The report also concludes that...
CBS Sacramento November 28, 2019 And as 2019 comes to a close, California is indeed home to the world’s largest cannabis market, totaling close to $12 billion in estimated sales. But here’s the rub: $8.7 billion of that is changing hands in the illicit market. Now, members of California’s cannabis industry are sending an S.O.S. to the state capitol, saying they’re struggling to compete against black market operators who don’t have to meet stringent regulations or pay taxes and fees.

When used in combination with alcohol, several drugs have the power to increase alcohol intake beyond what a...
(The drug use infused lies continue – Let’s not let facts get in the way of a good marijuana myth!) We also don’t have good data for state prisons — where more than 87 percent of US prison inmates are held, based on federal data . But we do know that a minority of state prisoners are in for drugs: In 2015, 3.4 percent of all state prisoners were in for drug possession and 11.7 percent were in for other drug-related crimes. So, again, only a fraction of prisoners are locked up due to drug...
Cannabinoid hyperemesis syndrome (CHS) is a condition that sometimes develops due to the use of marijuana. The syndrome causes repeated and severe vomiting and nausea. It is important for people with CHS to stop using marijuana because this will resolve their nausea and vomiting. Preventing dehydration and stopping nausea and vomiting are the treatment goals during the hyperemesis stage of the condition. When people with CHS stop using marijuana, their symptoms of nausea and vomiting usually...

One year after the legalization of recreational use of cannabis in Canada, the black market for the drug — as well as its use behind the wheel — continues to keep Quebec police forces busy. In 2018, police collected 795 blood samples from motorists suspected of driving while under the influence, and sent them to Quebec’s medical legal centre for processing. That’s 254 more than in the previous year. The presence of cannabis was detected in 46 per cent of those cases. More than 670 officers...

Canada was the second country in the world to legalize marijuana (Uruguay was the first). The legalizing act calls it “cannabis” of course. So much more genteel than marijuana, eh? “Cannabis” sounds scientific, well-researched – while marijuana sounds kind of louche and stoned, too close to low-rent, pejorative sobriquets like pot, weed, hash, grass, ganja, reefer et al. But it’s still marijuana, and I still call it that, because the people who worked hardest to get it legalized did their best...

Though the legal purchase age is 21 in Colorado and Washington, parents, educators and physicians say youths are easily getting hold of edibles infused with tetrahydrocannabinol, or...
A young adult's proximity to the location of medical marijuana dispensaries appears to be associated with a higher likelihood of marijuana use, with storefront advertising having the strongest influence on behavior. A RAND Corporation study examining trends in Los Angeles County drew this conclusion and is published online in the journal Addiction . “Our findings suggest that as the marijuana retail outlets become more visible and more numerous, they may influence the way that young adults...
Millions of Americans get behind the wheel while high from smoking marijuana, a study released on Wednesday said. An estimated 14.8 million Americans said they’ve driven while high at least once in the past month and nearly 70 percent believe they won’t get busted by cops, according to the American Automobile Association. “It’s terrifying,” said Helen Witty, the national president for Mothers Against Drunk Driving. “Impairment is impairment. We should be terrified, as law abiding citizens,...

Adolescent cannabis use is associated with behavioral changes related to reward and motivation in humans. Paradoxically, this use has both been suggested to increase motivation for other drug use (the gateway hypothesis) and a potential "amotivation syndrome" in which individuals are less willing to expend effort to receive a reward. Growing up high: Neurobiological consequences of adolescent cannabis use ( May, 2019)
The rationale for legalization varies, from achieving “social justice” (even though racial disparities in arrests persist in legalized states like Colorado or Washington ) to more blatant appeals to greed. The global legal market has been estimated at $9.5 billion for 2017 , with investor testimonials projecting future markets at values between $300 and $500 billion in a few short years. But not all signs are rosy. The evidence to date—such as the consequences in states like Colorado where...
BOSTON – A consortium of clinicians and scientists from across Massachusetts has joined together to publicly release a "Satement of Concern” expressing their disagreement with how marijuana policy is being shaped in the Commonwealth. According to the Statement of Concern , marijuana is being governed and regulated as if it were an “ordinary commodity”, rather than following a Public Health Framework. This is of concern because scientific evidence clearly establishes that marijuana (and...

Abstract BACKGROUND: Cannabis for medicinal and/or recreational purposes has been decriminalized in 28 states as of the 2016 election. In the remaining states, cannabis remains the most commonly used illicit drug. Cardiovascular effects of cannabis use are not well established due to a limited number of studies. We therefore utilized a large national database to examine the prevalence of cardiovascular risk factors and events amongst patients with cannabis use. RESULTS: Prevalence of heart...

More than 22,000 people were treated last year for cannabis addiction - and almost half of those affected were under 18. With doctors and drugs experts warning that skunk can be as damaging as cocaine and heroin, leading to mental...
In Amsterdam and London, specifically, there was a strong tie between the use of high-potency cannabis and the presence of psychosis. The researchers linked four in 10 (43.8 percent) new cases of psychosis in Amsterdam to daily cannabis consumption and five out of 10 (50.3 percent) of new cases with the use of highly potent versions of the drug. In London, the researchers believe they could link 21.0 percent of new cases to daily use and 30.3 percent to a preference for highly potent cannabis....

Whatever you think about marijuana legalization, it’s important to avoid making bad arguments. There may be good reasons to legalize marijuana. But if there are, the following arguments shouldn’t be considered to be among them. 7 Arguments For Legalizing Marijuana That No One Should Believe
(10 March 2019) Here is the problem. We are told that stabbings are at their worst since 1945. This is itself untrue. The year 1945 is chosen because that was when figures on stabbings began to be collected. In reality, they are the worst figures since this became a civilised country under the Victorians, really the worst figures since an unpoliced London was roamed by armed footpads, and highwaymen haunted the country roads. In a way, they are even worse than then. This is, by comparison with...
Chapter I: Cannabis and cannabinoids for medical, scientific and "recreational" use: risks and benefits Recommendations Under medical cannabis programmes implemented in Canada and possibly in some other States, and in some states in the United States, the medical use of cannabinoids is poorly regulated. Those programmes are inconsistent with the international drug control treaties in failing to control cannabis production and supply. They fail to ensure that good-quality medicines are provided...

From the Abstract Cannabis has been shown to be teratogenic in cells, animals and humans. Particular targets of prenatal exposure include brain, heart and blood vessels and chromosomal segregation… Studies in cells, together with the above mentioned epidemiology, implicate cannabidiol, cannabichromene, cannabidivarin and other cannabinoids in significant genotoxicity and/or epigenotoxicity. Notch signalling has recently been shown to be altered by cannabinoids, which is highly pertinent to...
We will, in years to come, look back and wonder how we could have been so foolish — so incredibly blind to the dangers of cannabis. We will be horrified at our reckless disregard for young minds. We will berate our liberally-minded politicians for their weakness, and the police for allowing, what is, in effect, its decriminalisation. And we will feel justifiable fury towards those who demanded the liberalisation of drug laws; who denied the mountain of evidence that this is a highly damaging...

I heard the news that Canada became the second country in the world to legalise the recreational use of cannabis and, in all honesty, it shocked me. Mums are smoking weed while pregnant to get rid of morning sickness The Prime Minister, Justin Trudeau, believes that legalising the drug will help keep marijuana away from underage users and reduce related crime, but in our experience of treating some 140 patients per month for various addictions, addiction to ‘harder’ drugs in our patients stems...
The acute and long-term effects of THC on the brain and behavior are mediated via the vast endocannabinoid system (ECS), which was not discovered until the early 1990s and remains poorly understood. However, addiction is addiction and the psychopathology associated with marijuana, especially the high potency products, amid the drumbeat for full legalization in the absence of any serious scientific scrutiny is tantamount to political malpractice. Use can be associated with psychosis,...

INTRODUCTION: Cannabis and its synthetic analogues are currently the most widely consumed illicit substances worldwide. Multiple alterations have been linked to its use, including cerebrovascular disease (CVD) or stroke, whose association with the substance has been based mainly on the hypothesis of transient vasoconstriction, which explains a large proportion of the cases reported. CONCLUSIONS: There is a wide variety of reports of stroke associated with cannabis use in patients with no other...

"They identified tobacco products as a cause of disease back in the 1950s," said Mahood, president of the Campaign for Justice on Tobacco Fraud. "They've never been able...
A new report by the Children’s Society on behalf of Public Health England highlights the relationship between sexual exploitation and drug use.

Date: July 6, 2016 Source: University of Michigan Health System Summary : Changes may increase risk of continued drug use and addiction Most people would get a little 'rush' out of the idea that they're about to win some money. In fact, if you could look into their brain at that very moment, you'd see activity in the part of the brain that responds to rewards. But for marijuana users, that rush just isn't as big -- and gets smaller over time, a new study finds. And that may open them up to...

Cannabinoid Hyperemesis Syndrome occurs by an unknown mechanism. Despite the well-established anti-emetic properties of marijuana, there is increasing...
David W. Murray, Brian Blake & John P. Walters Summary : Thanks to advances in science, we have never known so much about the effects marijuana use has on the human body, particularly, the fragile brain. Yet, in a political era when scientific research is regularly marshalled to end public policy debates, the powerful, growing scholarship on marijuana has largely been ignored or dismissed.

A highly-publicized study finding that marijuana use is linked to a severe drop in IQ has been successfully defended by the scientific community overseas and in the United States, including the National Institute on Drug Abuse Director Dr. Nora Volkow. The original study, published last August in the Proceedings of the National Academy of Sciences by Dr. Madeline Meier of Duke University, and colleagues, was the strongest evidence yet that teen use of cannabis could cause a drop in IQ....
By CBS News Staff (CBS/AP) Teens who smoke marijuana frequently are more likely to experience a long-term drop in their IQ, according to a new study. That could be a potential pitfall for millions of teens, given recent estimates show about one in 10 teens in grades nine through 12 smoke marijuana at least 20 times per month. The researchers however didn't find the same IQ dip for people who became frequent users of pot after 18, suggesting pot use is especially dangerous for the developing...
Fran Lowry October 20, 2016 Legalizing medical marijuana may have an adverse effect on educational attainment, new research shows. A study examining the impact of laws that legalize marijuana on educational attainment shows that states with these laws had an increase in the high-school dropout rate among 12th graders. In addition, among those who did graduate from high school, fewer went on to attend college or to graduate from college. The study was published online October 11 in Drug and...

Summary Points The US states that have legalized retail marijuana are using US alcohol policies as a model for regulating retail marijuana, which prioritizes business interests over public health. The history of major multinational corporations using aggressive marketing strategies to increase and sustain tobacco and alcohol use illustrates the risks of corporate domination of a legalized marijuana market. To protect public health, marijuana should be treated like tobacco, not as the US treats...
October 22, 2016 New data presented at this year's International Early Psychosis Association (IEPA) meeting in Milan, Italy (20-22 October) adds to accumulating evidence that high-potency cannabis in associated with an increased risk of users becoming dependent on cannabis. The analysis is by Dr Tom Freeman at University College London, UK. Estimates suggest around 182 million people worldwide use cannabis each year, a number that could rise as legalisation of recreational use and/or medical...

A Growing Threat to Our Youth There are several reasons that marijuana should no longer be called a soft drug, which is misleading. The cannabis of today is undeniably a hard drug. Dr. Darryl Inaba, Director of an addictions recovery center in Medford, Oregon was recently interviewed on the science of marijuana addiction. He said: “As a clinician who has worked with those who experience medical, emotional and social problems from its use for the past 40 years, I am concerned about the life...
People who regularly smoke large amounts of cannabis have reduced bone density and are more prone to fractures, research has found. The study also found that heavy cannabis users have a lower body weight and a reduced body mass index (BMI), which could contribute to thinning of their bones. “Our research has shown that heavy users of cannabis have quite a large reduction in bone density compared with non-users and there is a real concern that this may put them at increased risk of developing...

Written by Honor Whiteman Published: 1 September 2016 The perception of marijuana as a harmful drug has reduced among American adults, leading to an increase in its use, according to new research published in The Lancet Psychiatry. Researchers suggest a rise in marijuana use in the U.S. is down to a reduced perception that the drug is harmful. Study co-author Dr. Wilson M. Compton, of the National Institute on Drug Abuse (NIDA), and colleagues found that between 2002-2014, marijuana use among...
Megan Brooks August, 2016 Adolescent boys who regularly use marijuana are at increased risk of experiencing persistent, subclinical psychotic symptoms, particularly paranoia and hallucinations, even after they stop using the drug, a new study suggests.

By Naomi Schaefer Riley August 20, 2016 | 5:35pm Pot for the poor! That could be the new slogan of marijuana legalization advocates. In 1996, California became the first state to legalize the use of medical marijuana. There are now 25 states that permit the use of marijuana, including four as well as the District of Columbia that permit it for purely recreational use. Colorado and Washington were the first to pass those laws in 2012. At least five states have measures on the ballot this fall...

“It’s just so difficult… you wouldn’t know." Megha Varier | Wednesday, July 6, 2016 Being fired from his job in May was a wake-up call that permeated through the relaxed mellowness induced by the marijuana Devank was hooked to. “I realized I had to get my act together before it was too late,” Devank says. Devank smoked pot for the first time during a college fest at the age of 19, giving in to his friends’ cajoling. After that first time, it became a weekend affair, but soon, he was cutting...
If you’re pregnant or planning to be, tobacco and alcohol are high on the list of things not to use. But do we need an equally loud message about avoiding cannabis too? Yes, say some Australian researchers who’ve linked cannabis smoking both before and during pregnancy to a higher risk of preterm birth – and possibly an increased risk of birth defects. It’s a message that should make would-be dads prick up their ears too. Some studies have already found a higher risk of health problems and...
Author: Robert L. DuPont, M.D. It comes as no surprise that the prevalence of marijuana use has significantly increased over the last decade. With marijuana legal for recreational use in four states and the District of Columbia and for medical use in an additional 31 states, the public perception about marijuana has shifted, with more people reporting that they support legalization . However, there is little public awareness, and close to zero media attention, to the near-doubling of past year...
(putting new spin on the term ‘THICK as a BRICK’!) “Compared with unexposed children, those who were prenatally exposed to cannabis had a thicker prefrontal cortex, a region of the brain involved in complex cognition, decision-making, and working memory.

BY MEGAN ARELLANO ON 06/12/2015 - Andrew Freedman, Colorado's director of marijuana coordination, said Thursday that most of the money from marijuana is going to the cost of legalization. “You do not legalize for taxation. It is a myth. You are not going to pave streets. You are not going to be able to pay teachers,” Andrew Freedman, director of Marijuana Coordination for Colorado, said on Boston Herald Radio yesterday. “The big red herring is the whole thing that the tax revenue will solve a...
The link between cannabis use and the development of psychosis is established. This systematic review and meta-analysis of 24 studies summarizes the evidence of the impact of cannabis use after the onset of psychosis (schizophrenia, schizoaffective, or bipolar if outcome was reported as number of psychotic episodes). Researchers compared the outcomes of those who continued using cannabis, those who stopped, and those who did not have cannabis use. Irrespective of the stage of the psychotic...

THERE’S a secret addiction sweeping across Australia and we aren’t hearing about it. We all know the damaging effects of the monster drug ice and other hard narcotics, but what about the substances that are a little easier to get and widely spread? Marijuana is not something you often associate with the word “addiction” or consider it to be dangerous, but many people are hooked on the drug and it’s a problem experts say we need to take more seriously. A National Epidemiological Study of...

“Executive function, impulse control, attention, psychomotor function and subjective intoxication were significantly worse after cannabis administration relative to placebo.” "Overall, the present study demonstrates that cannabis induced impairment does not depend on cannabis use history and indicates that tolerance to impairing effects of cannabis on neurocognitive function is generally absent in frequent users. These data confirm previous suspicions that neurocognitive impairments during...
Wilkinson ST1, Stefanovics E, Rosenheck RA.

Parekh JD, Wozniak SE, Khan K, Dutta SK. Abstract The antiemetic properties of marijuana are well known, but there is increasing evidence of its paradoxical hyperemetic effects on the gastrointestinal tract and central nervous system, known as 'cannabinoid hyperemesis syndrome' (CHS). We report a case of CHS encountered in our outpatient clinic. We also completed a review of the literature using PubMed in patients over 18 years of age with CHS.

By Heidi Heilman | March 3, 2016, 14:23 EDT We have, for some time, known that the more marijuana there is in our communities, the more opiate and heroin use rises. Now, brain science is beginning to explain why. Studies reveal that the cannabinoid-opioid systems of the brain are intimately connected. There is a functional interaction between the mu and Cb1 receptors of the brain and these receptors commonly exist together on brain cells. In the areas of the brain where cannabinoids bind,...
