In the American Sniper trial, Eddie Ray Routh’s plea was countered when he pleaded not guilty because of insanity. Prosecutors said that he wasn’t psychotic, that he was just high. Even to this day, scientists keep arguing over marijuana and whether it can cause psychotic symptoms.

Dr. Nora Volkow, the National Institute for Drug Abuse at the National Institutes for Health’s director says it can cause psychosis in some, and is investigating whether it can cause shizophrenia.

A few researchers are convinced that pot use can contribute to schizophrenia. Studies show that cannabis users are much more likely to suffer from a psychotic episode when compared to those who don’t. In fact, one study showed that those who suffer from schizophrenia are more likely to become drug addicts when compared those who don’t suffer from the disease.

Some people have countered this argument by saying that those who already suffer from psychosis smoke pot, as opposed to pot being the cause of the psychosis itself. There is also the belief that those who do suffer from mental distress smoke weed because they are trying to self medicate.

But more people are using marijuana in this country than ever. So I guess if a lot more people are schizophrenic in a couple years, then I guess we could suspect there’s a connection. And that’d be such a bummer I’d just have to sit down and do a few dabs to get over it.
