Monthly cannabis use increased by nearly 10% among people with psychosis after legalisation in the United States, researchers have found.

The study, published in JAMA Psychiatry, found that the 30-day usage rate of the drug among individuals with psychosis in states that have legalised it increased by 9.5%.
