While there are many pro marijuana advocates, who say that marijuana has no negative effects on the human brain, this statement is patently false. This is like saying that caffeine and nicotine have no negative effect on people. These compounds are created by plants as insecticides.
Would you think it would be a smart idea to go to your local hardware store, buy some insect spray, and drink a tablespoon of it?
Unless they were trying to kill themselves, no sane person would do such a thing. While marijuana may not kill you directly, it can lead to psychosis in those with bipolar disorder and schizophrenia, which will invariably lead to a suicide attempt or hospitalization.
Manic depressives have a lower tolerance to toxins. While marijuana may make one feel better for a short period of time, it will usually trigger feelings of paranoia or anxiety.
Keep in mind that drugs are illegal and unregulated, so the amount of THC and the authenticity of it is not certain, so you don’t know if the product that you’re getting is going to throw you into psychosis.
Put simply, for someone with bipolar disorder to smoke marijuana over a long period of time is pretty much a guarantee of memory loss, psychosis, hospitalization, or suicide. Don’t waste your time or money ruining your life.
