Cannabinoid Receptor Sites

From My Health News 2012-11-19:

No, it’s not a flashback to Reefer Madness. New research at King’s College London’s Institute of Psychiatry (Biological Psychiatry, Nov.15, 2012), indicates a genetic marker may increase the risk of psychosis from smoking cannabis.

“People who smoke pot may be at increased risk for psychosis if they have a certain genetic marker, a new study finds.

“The results show people with this genetic marker who use cannabis are twice as likely to experience psychosis compared with those who use the drug but do not have the genetic marker.” [ . . . . ]

“The genetic marker in question is one variation of a gene call AKT1. The new finding confirms earlier research, which also linked this marker with the risk of psychosis after smoking pot.” [ . . . . ]  The genetic marker likely acts along with other genes to contribute to the risk of psychosis[.]”
