Smoking marijuana can raise your risk of developing a psychotic illness by 40 percent, British researchers say.
41% increased risk
They found that people who had used marijuana were 41 percent more likely to have a psychosis compared with people who had never used the drug. They also found that the risk increased as the amount of marijuana used and the length of time someone used the drug increased.
Link is real
One expert believes the link between marijuana and the risk for psychosis is real, and needs to be viewed as a problem much like tobacco and its health risks.
