Smoking Marijuana Linked to Early Onset Psychosis

Recent studies have linked the use of marijuana with the onset of psychosis. The meta-analysis found that those who smoked marijuana developed psychotic disorders an average 2.7 years earlier than those who did not use the drug. The review, however, found that people who use any illicit and mind-altering chemicals experienced psychosis two years earlier than non-users.

CannabisWhile alcohol use was not associated with early onset psychoses such as schizophrenia, the research results couldn’t rule out the influence of cigarette smoking, which consequently is a regular habit of people with psychotic disorders and marijuana smokers. In many of the countries from where the data was collected, cannabis is usually smoked mixed with tobacco.

However, based on the meta-analysis, researchers found that the tie continued independent of such factors. Marijuana smoking is therefore dangerous for people with a family history of psychosis.

Researchers, in the new study, also cited research that linked a particular gene to sensitivity to marijuana, which helps to explain why most marijuana smokers do not have a higher risk of schizophrenia.

None of the data, though, which links psychosis to marijuana use can prove causality or explain why rates of schizophrenia have remained stable or even declined since the 1950s
