A new study on cannabis and suicide has been published in The British Journal of Psychiatry (2009) 195: 492-497.

The researchers conclude that Although there was a strong association between cannabis use and suicide, this was explained by markers of psychological and behavioural problems. These results suggest that cannabis use is unlikely to have a strong effect on risk of completed suicide, either directly or as a consequence of mental health problems secondary to its use.
