LONDON, England (AP) -- 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.

Some experts say governments should now work to dispel a misconception that marijuana is a benign drug.

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.
