A study has found that more than a quarter of new cases of psychotic disorders are linked with the usage of “high potency ’skunk-like' cannabis.”
Compared with someone who never smoked, a weekly user of high-potency pot--which the authors define as having more than 15 percent THC--were three times more likely to develop psychosis, according to the study. For people who use smoke daily, the risk jumps to around five times higher.
The authors of the study, who are with King’s College in London, said there was no link between frequent use of low-potency marijuana, which is defined as having less than 5 percent THC, and a psychotic disorder.
