Marijuana and mental health

Marijuana may increase psychosis risk, analysis says

Excerpt:

Using marijuana seems to increase the chance of becoming psychotic, researchers report in an analysis of past research that reignites the issue of whether pot is dangerous.


The new review suggests that even infrequent use could raise the small but real risk of this serious mental illness by 40 percent.


Doctors have long suspected a connection and say the latest findings underline the need to highlight marijuana's long-term risks. The research, paid for by the British Health Department, is being published Friday in medical journal The Lancet.


Smoking just one cannabis joint raises danger of mental illness by 40%

Excerpt:

A single joint of cannabis raises the risk of schizophrenia by more than 40 per cent, a disturbing study warns.


The Government-commissioned report has also found that taking the drug regularly more than doubles the risk of serious mental illness.


Overall, cannabis could be to blame for one in seven cases of schizophrenia and other life-shattering mental illness, the Lancet reports.


Comment: While, I have never used marijuana before, I have limited personal experience with this. I know several who were heavy marijuana users in their youth. Now in their 30's ... well let's just say "they aren't quite right!".
