Daily Marijuana Use And Highly Potent Weed Linked To Psychosis

Weed use is taking off as more states move to legalize it. And with all the buzz over medical marijuana, it’s starting to gain an aura of healthfulness. But there are some serious health risks associated with frequent use. One of the more troubling ones is the risk of having a psychotic episode.

Several past studies have found that more frequent use of pot is associated with a higher risk of psychosis, that is, when someone loses touch with reality. Now a new study published Tuesday in the The Lancet Psychiatry shows that consuming pot on a daily basis and especially using high potency cannabis increases the odds of having a psychotic episode later.

“This is more evidence that the link between cannabis and psychosis matters,” says Krista M. Lisdahl, a clinical neuropsychologist at the University of Wisconsin, Milwaukee, who wasn’t involved in the study.

The study authors consider “high potency cannabis” to be products with more than 10 percent tetrahydrocannabinol or THC, the compound responsible for the drug’s psychoactive effects. The fact that consuming high THC cannabis products has a greater risk is concerning, Lisdahl says, because these products are more common in the market now. [Read More @ NPR]
