People who start smoking cannabis to alleviate pain, anxiety or depression are at a higher risk of developing paranoia than those who use the drug recreationally, a study has found.

The research analysed answers from 3,389 former and current cannabis users aged over 18, who had no clinical history of psychosis and had taken part in the Cannabis&Me survey.
