INDIVIDUALS WHO USE cannabis every day are three times more likely to suffer from a psychotic disorder than those who don’t use the drug at all, a new study has revealed.
The study, which examines how cannabis use and strength affects the incidence of psychosis, found that the odds of having the disorder among daily users of the drug were 3.2 times higher than among non-users.
It also found that users of high-potency cannabis were approximately 1.6 times more likely to have a psychotic disorder than those who never used the drug.
The study, published today in The Lancet Psychiatry journal, claims to be the first to show the impact of cannabis use on population rates of psychosis, and highlights the potential public health impact of changes to the legal classification of cannabis.
