In The Lancet Psychiatry, Schoeler and colleagues present a study describing the mediating effect of medication adherence on the association between continued cannabis use and relapse risk in patients with first-episode psychosis. They have previously reported a relapse rate of 36% in this patient group over a 2-year period.
Acknowledging the potential risk of psychosis relapse related to the high proportion of patients continuing cannabis use after the onset of psychosis, the current study1 investigates the same patient group consisting of 245 patients, obtaining retrospective data on active cannabis use and medication adherence shortly after illness onset, as well as risk of relapse at 2-year follow-up. The authors find that relapse of psychosis associated with continued cannabis use is partly mediated through non-adherence to prescribed antipsychotic medication.
It is well established that cannabis use increases the risk of schizophrenia, not only from the early Swedish conscript studies but also from studies on people who use sinsemilla in London, UK, showing that high potency cannabis increases the risk of schizophrenia. Twin studies from Norway have shown that cannabis increases the risk of psychosis, even when controlling for genetic factors. There has been discussion on the direction of the association, as none of these studies can rule out reverse causality, but it seems reasonable to conclude that cannabis is one of many stressors that can precipitate schizophrenia, at least in susceptible individuals.

Toxic substances such as nicotine and alcohol from alcoholic drinks can travel quickly through an expectant mother's placenta to her unborn baby, says a researcher from the University of Eastern Finland. The research showed that the placenta does not shield the foetus, but revealed that alcohol and nicotine can travel from mother to child in less than two hours.
Cannabis harm prevention messages are essential, according to police in places where the drug has been decriminalised. Government, police and health agencies need clear guidelines for public campaigns on preventing harm from cannabis use, according to new research from Massey University. Front line police officers she interviewed in the Netherlands and states of Colorado and Oregon in the United States, where recreational cannabis use is not an offence, provided insights on how their communities responded with cannabis legally available.
They said that contrary to expectations, legalising the drug did not eliminate crime related to selling it, or gangs from continuing to profit from its sale.
All of her interviewees had cannabis law reform presented as a positive change for police, yet – as one officer said, "we just have not seen all the wonderful promises that were made to us."
Others observed cannabis was a gateway to harder drugs, and one officer expressed concern that the legal cannabis industry was attempting to target children to create a future market.
Front-line police officers she interviewed noted the following issues:
- the enduring role organised crime plays in profiting from cannabis
- inconsistent police policies are exploited, resulting in erosion of perceived police effectiveness
- driving while cannabis-impaired is a largely unmitigated risk, which may be a significant factor in vehicle crashes
- cannabis regularly misused by youth causes learning difficulties and leads to poor social outcomes
- it is important, and sometimes difficult, to get harm-prevention messaging right
What was going through Salman Abedi’s mind when he made that journey to Manchester Arena on Monday night? How does someone do something so unspeakably evil as to slaughter and grievously injure innocent young children in this way?
Was he a psychopath? Was he evil? I do not know the answer but I do know, as the Mail reports today, that according to his friends Abedi was a frequent and heavy cannabis smoker.
Studies into the personality type of would-be jihadi terrorists have found some recurring themes that make an individual ‘ripe’ for radicalisation. They tend to feel angry, alienated or disenfranchised.
There is also a strong sense of victimhood and that they are fighting for a social injustice.
They have a poor sense of identity and tend to be ‘adolescent’ and petulant. This kind of personality type, combined with cannabis use, surely produces an individual more receptive to the kind of hate-filled rhetoric peddled by radical Islamists.
For too long, we have ignored the terrible toll of this drug. Too many people have dismissed cannabis as harmless — something to help you relax and chill — and that an individual should be free to buy and use as they choose.
Now, more than ever, we need to wake up to a pernicious substance that ruins not just the lives of those that take it, but countless others around them in ways we might never have imagined.

Breast cancer is the most common form of cancer among women across the globe. New research suggests that as little as one alcoholic drink per day can increase breast cancer risk, while exercise and a healthful diet lowers the risk.
In 2012, 1.7 million cases of breast cancer were diagnosed across the globe, which makes up 25 percent of all cancer diagnoses in women.
Worldwide, breast cancer is the second leading cause of cancer-related death among women. In the United States, almost 231,000 women were diagnosed with breast cancer in 2013, along with more than 2,100 men.
