In L.A. marijuana is legal medicine.

Mellow, mellow medicine.

But can marijuana make you insane in the membrane?

Don't blow your smoke in our face for relaying the news here. But the answer seems to be yes, especially if you started smoking as a teenager and continued.

That's according to a recent study published in the British Medical Journal, which concludes:

Cannabis use is a risk factor for the development of incident psychotic symptoms. Continued cannabis use might increase the risk for psychotic disorder by impacting on the persistence of symptoms.

Researchers looked at 1,923 people who range in age from 14 to 24 over a 10-year span.

Young people who were fairly sane and started smoke weed nearly doubled their chances of seeing "psychotic symptoms."

One expert, Tomas Silber, an adolescent medicine doctor at the Children's National Medical Center in Washington, D.C., tells WebMD this (and it's not good news for medical marijuana supports in California):

Many people have suspected that people smoke marijuana as a way of treating themselves, and this study disproves that connection. It is not a two-way street, it's a one-way street.
