I was in a roundtable discussion with some fellow psychiatrists debating the connection between cannabis and schizophrenia. There are as many opinions on the subject as there are shades of grey. As with most scientific endeavors, the investigation into the putative link between cannabis and psychosis is one of slow progress, setbacks, and breakthroughs.

This week, Scientific American reports on a new study which appears to support the link and strengthens the argument that Cannabis use needs to be done with extreme caution, particularly in the setting of personal or family history of schizophrenia or psychotic disorders.

Personalized medicine note: Some COMT gene variants increases risk of psychosis up to 10 fold. That is a discussion for another day.
