Cannabis and Psychosis

Introduction

Cannabis use in any of its forms cause significant mental health problems. Many studies had indicated about for years. Any person who engages in mental health knows the harmful effects of these substances. Despite clear data, force media supporters of this drug, has denied evidence, often relying on studies with weak or just poorly designed statistical approach.

The Lancet, perhaps the scientific journal prestige in medicine, has just published a meta-analysis (subscription required) on the topic, that is, a study that gathers data from multiple studies and analyzes together, giving each data valid determined according to quality. Article Summary data can be found in the press (Henquet et.al, 2009).

The study concludes that cannabis increases between 40% and 200% risk of schizophrenia and other psychoses, depending on how much they smoke cannabis.

Acute cannabis intoxication can cause symptoms such as depersonalization, de-realization, feeling of loss of control or paranoid ideas, which are usually transient and of short duration (Manrique-Garcia et.al, 2012).

This cohort study evaluated the association between the onset of cannabis use and incidence of psychotic experiences or symptoms and risk of psychotic disorder in adolescents and young adults between 14 and 24. To this end the prevalence of cannabis use (at least 5 times) and psychotic symptoms at baseline, 3.5 years and measured about 8.4 years. The risk of psychotic symptoms or disorders was not analyzed according to the frequency of consumption.

Among individuals who had never used cannabis and psychotic experiences had at the time of entering the study, the onset of cannabis use before 3.5 years of follow-up increased the risk a posteriori (between ...
