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!
Moore and colleagues9 … found that individuals who had used cannabis had a significant, 1.4-fold increased risk of any psychotic outcomes, independent of potential confounding and transient intoxication effects. Findings also provided evidence for a dose-response effect, with even greater, 2.1-fold risk in individuals who used cannabis most frequently.
More recently, Marconi and colleagues10 performed a meta-analysis of 10 studies, including 66,810 individuals, that investigated the association between the degree of cannabis consumption and risk of psychosis. In all individual studies, higher levels of cannabis use were associated with increased risk of psychosis. They also found evidence for a dose-response relationship, with a 2-fold increase in risk for the average cannabis user, and a 4-fold increase in risk for the heaviest users, compared with non-users.
Introduction: This paper compares consequences of cannabis use initiated after high school with those of cannabis initiation in adolescence, with estimates of the proportion of adverse consequences accounted for by adult-onset and adolescent-onset cannabis users.
Methods: A state-representative sample in Victoria, Australia (n = 1792) participated in a 10-wave longitudinal study and was followed from age 15 to 35 years. Exposure variable: Patterns of cannabis use across 20 years. Outcomes at age 35: Alcohol use, smoking, illicit drug use, relationship status, financial hardship, depression, anxiety and employment status.
Results: Substantially more participants (13.6%) initiated regular use after high school (young-adult onset) than in adolescence (7.7%, adolescent onset). By the mid-30s, both young-adult and adolescent-onset regular users were more likely than minimal/non-users (63.5%) to have used other illicit drugs (odds ratio [OR] > 20.4), be a high-risk alcohol drinker (OR > 3.7), smoked daily (OR > 7.2) and less likely to be in relationships (OR < 0.4). As the prevalence of the young-adult-onset group was nearly double of the adolescent-onset group, it accounted for a higher proportion of adverse consequences than the adolescent-onset group.
Discussion and conclusions: Cannabis users who began regular use in their teens had poorer later life outcomes than non-using peers. The larger group who began regular cannabis use after leaving high school accounted for most cannabis-related harms in adulthood. Given the legalisation of cannabis use in an increasing number of jurisdictions, we should increasingly expect harms from cannabis use to lie in those commencing use in young adulthood.
Is weed a gateway drug at any age? Frequent users are three times more likely to be heavy drinkers and 20 TIMES more likely to use other drugs - no matter when they start smoking marijuana
Researchers compared people who began regularly using marijuana as teenager and as adults to non-users
People who began using pot as adolescents were 20.4 times more likely to be illicit drug users and 3.7 times more likely to be a high-risk alcohol drinkers
They were also 7.2 times more likely to smoke cigarettes daily and 0.4 times less likely to be in a relationship
Weed users who began as adults were 36.8 times more likely to use illicit drugs, 3.2 times more likely to be heavy drinkers
These people were 7.3 times more likely to smoke cigarettes daily and 0.3 times less likely to be in a relationship
Peer deviance is associated with higher odds of cannabis use.
PRS is associated with higher odds of cannabis use among subjects who never engage with community activities.
Analyses in African American subjects were inconclusive due to limited portability of the PRS.
Church activities is associated with lower odds of cannabis use.
Abstract
Background: Among adult college students in the US, cannabis use is common and associated with considerable negative consequences to health, cognition, and academic functioning, underscoring the importance of identifying risk and protective factors. Cannabis use is influenced by genetic factors, but genetic risk is not determinative. Accordingly, it is critical to identify environments that reduce risk among those who are at elevated genetic risk. This study examined the impact of polygenic scores for cannabis initiation, various forms of social activity participation, and peer deviance on recent cannabis use. Our aim was to test whether these environments moderate genetic risk for cannabis use.
Methods: Data came from a longitudinal sample of undergraduate college students of European American (EA; NEA = 750) and African American (AA; NAA = 405) ancestry. Generalized estimating equations with a logit link function were used to examine main effects and two-way interactions.
Results: Engagement with church activities was associated with lower probability of cannabis use. Peer deviance was associated with higher probability of cannabis use. Engagement with community activities moderated the influence of the polygenic risk score in the EA sample, such that PRS was associated with recent cannabis use among those who never engaged in community activities. This effect did not replicate in AAs, which may have been due to the portability of PRS based on EA discovery samples.
Conclusions: Results suggest that community activities may limit the influence of genetic risk, as associations between PRS and cannabis use were only observed among individuals who never engaged in community activities.

Question Is cannabis use disorder associated with heightened risk of self-harm, suicide, and mortality among youths with mood disorders?
Findings This population-based cohort study of Medicaid-enrolled youths with mood disorders found that the presence of cannabis use disorder was significantly associated with an increased risk of nonfatal self-harm, all-cause mortality, and death by unintentional overdose and homicide.
Meaning Cannabis use disorder is common among adolescents and young adults with mood disorders and is associated with an elevated risk of self-harm, overall mortality, and death by unintentional overdose and homicide in this already vulnerable population.
Abstract
Importance Cannabis use and cannabis use disorder (CUD) are common among youths and young adults with mood disorders, but the association of CUD with self-harm, suicide, and overall mortality risk is poorly understood in this already vulnerable population.
Objective To examine associations of CUD with self-harm, suicide, and overall mortality risk in youths with mood disorders.
Results This study included 204 780 youths (133 081 female participants [65.0%]; mean [SD] age at the time of mood disorder diagnosis, 17.2 [4.10] years). Cannabis use disorder was documented for 10.3% of youths with mood disorders (n = 21 040) and was significantly associated with older age (14-18 years vs 10-13 years: adjusted risk ratio [ARR], 9.35; 95% CI, 8.57-10.19; and 19-24 years vs 10-13 years: ARR, 11.22; 95% CI, 10.27-12.26), male sex (ARR, 1.79; 95% CI, 1.74-1.84), Black race (ARR, 1.39; 95% CI, 1.35-1.44), bipolar or other mood disorders (bipolar disorders: ARR, 1.24; 95% CI, 1.21-1.29; other mood disorders: ARR, 1.20; 95% CI, 1.15-1.25), prior history of self-harm (ARR, 1.66; 95% CI, 1.52-1.82), previous mental health outpatient visits (ARR, 1.26; 95% CI, 1.22-1.30), psychiatric hospitalizations (ARR, 1.66; 95% CI, 1.57-1.76), and mental health emergency department visits (ARR, 1.54; 95% CI, 1.47-1.61). Cannabis use disorder was significantly associated with nonfatal self-harm (adjusted hazard ratio [AHR], 3.28; 95% CI, 2.55-4.22) and all-cause mortality (AHR, 1.59; 95% CI, 1.13-2.24), including death by unintentional overdose (AHR, 2.40; 95% CI, 1.39-4.16) and homicide (AHR, 3.23; 95% CI, 1.22-8.59). Although CUD was associated with suicide in the unadjusted model, it was not significantly associated in adjusted models.
Conclusions and Relevance Cannabis use disorder is a common comorbidity and risk marker for self-harm, all-cause mortality, and death by unintentional overdose and homicide among youths with mood disorders. These findings should be considered as states contemplate legalizing medical and recreational marijuana, both of which are associated with increased CUD.

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...

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....

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...

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...

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...

This is just the beginning, pulmonary researchers caution. By Alexandra Pattillo on December 4, 2019 After using a marijuana vape pen for just six months, a 49-year-old retired dog trainer went to the doctor coughing and wheezing, reporting shortness of breath upon exertion. The woman had smoked off and on through her teens and twenties, but was healthy — other than her worrying throat symptoms. Her doctors gave her a rare and surprising diagnosis: hard-metal pneumoconiosis — a lung disease...
Association Between Marijuana Use and Risk of Cancer: A Systematic Review and Meta-analysis Conclusions and Relevance Low-strength evidence suggests that smoking marijuana is associated with developing TGCT; its association with other cancers and the consequences of higher levels of use are unclear. Long-term studies in marijuana-only smokers would improve understanding of marijuana’s association with lung, oral, and other cancers....

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. They’re...

BU researcher finds that miscarriages are more likely when the father uses marijuana weekly - If a man habitually uses marijuana even as little as once a week, could that increase the risk of his partner experiencing a miscarriage in early pregnancy? A first-of-its-kind study suggests so. By analyzing more than six years of lifestyle and behavioral data from 1,535 heterosexual couples actively trying to conceive, Boston University School of Public Health researcher Alyssa Harlow discovered...
Teenagers suffer higher rates of addiction when recreational cannabis is legalised - study New research about legal cannabis has revealed a sobering statistic. In states where recreational marijuana has been legalised, teenagers are suffering higher rates of addiction. The study of 505,796 respondents was carried out by researchers from New York University's School of Medicine. It compared use of the drug before and after legalisation in the US. The proportion of people aged 12 to 17 who...
Medical Xpress: Frequent cannabis (marijuana) use among young people was linked to an increased risk of stroke and people diagnosed with cannabis use disorder were more likely to be hospitalized for heart rhythm disturbances (arrhythmias), according to two new preliminary studies to be presented at the American Heart Association's Scientific Sessions 2019 "The effects of using cannabis are seen within 15 minutes and last for around three hours. At lower doses, it is linked to a rapid...
A new study found that when people use alcohol and drugs together, their risk for an alcohol overdose increases. The study looked at 660 patients who had experienced alcohol poisoning, passing out, or blacking out events, and found only 20 percent had been using alcohol alone. The most common drug used in combination with alcohol users who experienced an alcohol overdose was marijuana. 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...

But what’s been a beacon of hope for North American drug policy reformers could be regressing towards punitive approaches that Americans are all too familiar with. On September 30, Rui Moreira, the mayor of Porto, contradicted his past pro-harm reduction positions, like the ones made at the 2019 Harm Reduction International conference in his own city, when he endorsed reintroducing criminal penalties for drug use in public spaces during a municipal assembly meeting. Drug decriminalization “is...
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...
Fascinating, yet predictable. Legalize a drug and you supposed ‘radically reduce’ crime, right?

VANCOUVER -- Marijuana and alcohol were the most common substances leading to hospitalization of youth aged 10 to 24 across the country, says a report that highlights the prevalence of mental-health conditions as contributing factors. About 23,500 people in that age group were hospitalized for harm caused by substance use, amounting to an average of 65 hospitalizations every day between April 2017 and March 2018, says the Canadian Institute for Health Information in a report released Thursday....
Research presented to the International Early Psychosis Association last year showed a link between cannabis use and schizophrenia. Among a sample of more than three million people, researchers found that cannabis abuse increased the risk, by five times, of developing schizophrenia. Parental use of cannabis increased the risk of schizophrenia in children. As with alcohol, no safe level of foetal cannabis exposure had been established. RANZCP president John Allan told The Australian that since...
Professor, Operations Research and Policy, Carnegie Mellon University, and the co-editor of Marijuana Legalization: What Everyone Needs to Know Whether one can overdose on cannabis depends on one’s definition of the word overdose. If overdose means any acute adverse health consequences of taking too much, then absolutely. There is no question cannabis can do that. If one means more narrowly death by the same physiological mechanism that is involved in opioid overdose (suppressed respiration,...

Colorado's experiment with marijuana legalization has been an epic disaster, according to one doctor seeing its effects on the front lines. Dr. Karen Randall, an emergency room physician certified in "cannabis science and medicine," said the legalization of marijuana has damaged, rather than helped, her home state. Randall said. "The grand experiment is not going so well. I don't think the public is hearing about this as they should be." Randall has seen a "marked increase in medical problems"...

Marijuana concentrates have about three times more THC, the...
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...
The study is among the first to report on voluntary oral THC consumption in animals, a method of consumption that is similar to the way humans take the drug.

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.

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...

The UN-backed International Narcotics Control Board (INCB) warned on Tuesday that poorly regulated medical cannabis programmes could step-up the “recreational” use of the drug while diminishing public concern over its harmful effects. “Legalization of cannabis for recreational purposes, as seen in a small number of countries, represents not only a challenge to the universal implementation of the treaties and the signatories to the treaties, but also a significant challenge to health and...
In this research: Some teens' marijuana use has been linked to disrupted communication between two key regions in the brain's reward circuitry at age 20.

In a recent NIDA-supported study, males from low-income backgrounds who used marijuana in escalating frequency throughout their teen years exhibited disrupted connectivity at age 20 in a brain circuit that links rewarding experiences...
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...

THE abduction, rape and murder of Alesha MacPhail has prompted calls for ministers at Westminster and Holyrood to change their soft-touch stance on cannabis. Campaigner Ross Grainger has compiled a “catalogue of suicide and psychopathic violence committed by cannabis smokers in the UK and Ireland” over the past two decades including 200 murders, rapes and savage assaults. He said: “In this case, as in all such cases, I do not say that cannabis 'caused' the perpetrator to do what he did, but...
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...

A new study on cannabis has found that users with mental illness present an increased risk of violent behaviour. The research conducted by the Institut en Santé Mentale de Montréal (Montreal Institute of Menal Health), studied 1,136 patients – from 18 to 40 years of age – with mental illnesses who had been seen five times during the year after discharge. And while previous research has already shown a link between cannabis and aggressive behaviour, this new study found that users who continued...
Author: Mark Gold, MD Ground-breaking research on the hippocampus and ECs has enhanced our knowledge of the role of molecular mechanisms necessary to process lipid EC messengers. It has been established that circuitry between the hippocampus and prefrontal cortex is disrupted by the introduction of exogenous cannabinoid and thus is correlated with impairments in behavior (Kucewicz et al., 2011). Cannabinoids may disrupt cortical function by desynchronizing neuronal communication across...

Published 1 October 2017 By Ana Sandoiu Butane hash oil is a cannabis extract made using butane. Researchers have analyzed the chemical composition of the vapors released by butane hash oil - a cannabis extract commonly used in "dabbing," or vaporizing - and found carcinogenic substances. In light of cannabis being legalized in several states across America, more and more people use marijuana recreationally. The practice of " dabbing " has also gained popularity; users think that dabbing is...
The authors continued, stating that the current study focused on the “chemistry of myrcene and other common terpenes found in cannabis extracts. Methacrolein, benzene, and several other products of concern to human health were formed under the conditions that simulated real-world dabbing. The terpene degradation products observed are consistent with those reported in the atmospheric chemistry literature.” Many of the terpenes that the researchers discovered in the vaporized hash oil are also...

Many people fail to realize that alcohol, although legal, costs employers and taxpayers millions of dollars each year. In 2010, the cost of excessive alcohol use in the United States reached $249 billion, and two out of every five dollars of those costs were paid by federal, state, and local governments—all funded by the taxpayer. In fact, of this $249 billion drain on the American economy, $179 billion is directly associated to workplace productivity, and an additional $28 billion to health...

Grant KS 1, Petroff R 2, Isoherranen N 3, Stella N 4, Burbacher TM 5. Abstract The broad-based legalization of cannabis use has created a strong need to understand its impact on human health and behavior. The risks that may be associated with cannabis use, particularly for sensitive subgroups such as pregnant women, are difficult to define because of a paucity of dose-response data and the recent increase in cannabis potency. Although there is a large body of evidence detailing the mode of...

Abstract Despite a documented relationship between cannabis use and suicidality, little is known about psychological vulnerability factors that may increase suicidality among this high-risk group. The Interpersonal-Psychological Theory of Suicide (IPTS; Joiner, 2005) proposes that people are vulnerable to wanting to die by suicide if they experience both perceived burdensomeness and thwarted belongingness. Daily cannabis users may be especially vulnerable to these factors. The current study...

AMERICAN HEART ASSOCIATION DALLAS, July 27, 2016 -- Rats' blood vessels took at least three times longer to recover function after only a minute of breathing second-hand marijuana smoke, compared to recovery after a minute of breathing second-hand tobacco smoke, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association. When rats inhaled second-hand marijuana smoke for one minute, their arteries...
Smoking cannabis affects the reward centre in a user's brain, scans show That is the region responsible for releasing 'pleasure' hormone dopamine In cannabis users, scans show less activity in the reward centre, so a smaller amount of dopamine is released That dampened, blunted emotional response means a marijuana smoker will need more of the drug to illicit the same reward - raising addiction risk By LIZZIE PARRY FOR DAILYMAIL.COM PUBLISHED: 07:21 EST, 7 July 2016 | UPDATED: 07:37 EST, 7 July...
"Many youth tend to think that alcohol use has more consequences than marijuana use and therefore view marijuana use as safer than drinking. However, youth need to better understand the harms of marijuana use, such as the potential effect on their developing brain and how it can affect performance in both adolescence and adulthood."

“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. Author of the study Dr. Hanan El Marroun, of Erasmus University Medical Center in The Netherlands, said: "this study is important because cannabis use during pregnancy is relatively common and we know very little about the potential...
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...
Written by Marie EllisPublished: Friday 15 April 2016 “Results showed that, compared with the control group, the marijuana users' striatum had lower dopamine release. There was also lower release in subregions that play a role in associative and sensorimotor learning, as well as in the globus pallidus.” For complete Article
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. Abstract OBJECTIVE : An increasing number of states have approved posttraumatic stress disorder (PTSD) as a qualifying condition for medical marijuana, although little evidence exists evaluating the effect of marijuana use in PTSD. We examined the association between marijuana use and PTSD symptom severity in a longitudinal, observational study. METHOD : From 1992 to 2011, veterans with DSM-III/-IV PTSD (N = 2,276) were admitted to specialized...
Authors Kelley ME, Wan CR, Broussard B, Crisafio A, Cristofaro S, Johnson S, Reed TA, Amar P, Kaslow NJ, Walker EF, Compton MT. Abstract OBJECTIVES : Several studies suggest that adolescent marijuana use predicts earlier age at onset of schizophrenia, which is a crucial prognostic indicator. Yet, many investigations have not adequately established a clear temporal relationship between the use and onset. METHODS : We enrolled 247 first-episode psychosis patients from six psychiatric units and...
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. Understanding the diagnostic criteria and risk...
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,...
by JENNY HOPE, Daily Mail More than 30,000 cannabis smokers could die every year, doctors warn today. Medical experts blame the Home Secretary for creating confusion about the risks posed by the drug - leading young people wrongly to believe it is harmless. They claim David Blunkett's decision to reclassify cannabis as a class C drug - putting it on a level with anabolic steroids and prescription painkillers - sent out the wrong message and played down the devastating health effects of its...
Cuts against many other studies that have showed pot doesn't have fatal health implications A recent German study claims to have documented the first known deaths resulting from marijuana use. While researchers studied 15 people whose deaths were allegedly linked to marijuana use, 13 of those deaths were confirmed to be caused by other factors. Researchers said, however, that the drug was to blame in two isolated cases of two seemingly healthy people, one 23 years old and another 28. Autopsies...
American College of Pediatricians – September 2015 ABSTRACT : Although increasing legalization of marijuana has contributed to the growing belief that marijuana is harmless, research documents the risks of its use by youth are grave. Marijuana is addicting, has adverse effects upon the adolescent brain, is a risk for both cardio-respiratory disease and testicular cancer, and is associated with both psychiatric illness and negative social outcomes. Evidence indicates limited legalization of...
