Smoking Marijuana Leads to Early Psychosis?

A new review tackled a very often-asked question: does smoking marijuana cause earlier psychosis?

All in all, 83 studies involving more than 22,000 participants were utilized to determine whether or not smoking marijuana had any impact on the onset of early psychosis.

The analysis found that individuals who smoked marijuana did in fact develop psychotic disorders around 2.7 years earlier, on average, than those who did not use the drug. This finding, coupled with the fact that people who abused any illegal drug suffered psychosis two years earlier than non-users, goes a long way in showing the dangers associated with abusing narcotics.

Interestingly, the review also noted that alcohol was not associated with the development of psychosis. This of course directly contradicts the statements that pro-marijuana groups have been making for years that alcohol’s side-effects are worse than those of cannabis.

The analysis, which was led by the University of New South Wales’ Matthew Large, also indicated that there were many other factors involved in the diagnosis of early psychosis.

Among these findings were: men were more likely to smoke marijuana and develop early psychosis than women and that young people were more likely to smoke than old people.
Specifically noted in the review was that it plainly and clearly indicated that there was a casual correlation between cannabis usage and early onset psychosis.

Perhaps the most important finding in the analysis, though, was that marijuana was particularly dangerous for people who had a family history of psychosis.

The one thing not addressed by the information was why while rates of schizophrenia have declined since the 1950s, marijuana usage has increased exponentially in that time. If there is in fact a link between the two, then there would have to be a more direct correlation between the numbers.
