Smoking strong pot daily increases psychosis risks

"They estimated that people who smoked marijuana daily were three times more likely to be diagnosed with psychosis compared with people who never used the drug, and the risk increased to almost five times more likely among those who used high-potency marijuana daily".

The research involved 901 patients aged 18 to 64 who have first-episode psychosis and have used mental health services in major sites across Europe between 2010 to 2015.

And for those who used high-potency pot on a daily basis, the risk of psychosis was even greater - four times greater than those who had never used. The study found the link between cannabis and psychosis was strongest in London and Amsterdam, where high potency skunk is commonly available.

In Amsterdam, the incidence of first-time psychosis would likely drop from 38 to 19 per 100,000 people per year, while in London, the number of cases would decline from 46 to 32 per 100,000 people. The researchers collected details about individuals' historical past of hashish use and different leisure medication.

"Daily use of high-potency cannabis and how this varies across Europe explains some of the striking variations we have measured in the incidence of psychotic disorder", coauthor Marta Di Forti of King's College London tells The Guardian.

One recent study showed that high-potency cannabis is increasingly dominating markets.

THC is the psychoactive compound in cannabis - the stuff that gets you "high".

A new study published Tuesday in the Lancet Psychiatry journal shows people who use cannabis every day or those who use high-potency weed are at increased risk of psychotic disorder.

The researchers then asked those diagnosed with psychosis as well as a group of more than 1,200 healthy people about their weed habits-things like if they used weed, how often, and what kind.

"Cannabis carries severe health risks and users have a higher chance of developing psychosis". But they note that the cut-off of 10% THC for potency is conservative.

While the correlation between marijuana use and mental disorders was strong, a cause-and-effect relationship can only be inferred, the authors cautioned. The strength of cannabis was estimated from the name individuals gave to the drug.

So how common is high-potency weed, anyway? It is perfectly possible that the association between cannabis and psychosis is bidirectional. Former deputy prime minister Sir Nick Clegg says making mild forms legally available would stop people using skunk.

Despite his skepticism, Armentano allowed that "the concerns raised in this paper ought to be taken seriously, and they provide an argument in favor of better regulation of the plant so that it can be better kept out of the hands of young people and those who may be at higher risk for an adverse reaction".

[3] Data derive from the Population Attributable Fraction (PAF) which measures the population effect of an exposure by providing an estimate of the proportion of cases that would be prevented if the exposure (ie, daily/high potency cannabis use) were removed.
