Higher-potency cannabis poses 'gravest threat' to young people's mental health 

The College of Psychiatrists of Ireland has launched two new information leaflets on cannabis to debunk the perception that the illegal substance is relatively harmless.

The College of Psychiatrists of Ireland has warned that the availability of increasingly potent cannabis combined with a widespread “misconception” that the drug is harmless poses the “gravest threat” to the mental health of young people in Ireland.

The college, which represents 1,000 psychiatrists across the country, has launched two new information leaflets on cannabis to debunk the perception that the illegal substance is relatively harmless.
