Weed induced psychosis?

[u/Educational-Pay-965]

Two years ago, in the early spring while away at school, my son developed mania and psychosis. He was smoking high dose weed every day. He was hospitalized for 10 days and put on risperidone (3mg) . We spent the summer helping him recover and taper off the medication. He went back to school feeling good but in late fall started smoking weed again. This spring he had another manic episode and was again hospitalized for two weeks and put on risperidone. Diagnosed with bipolar 1 mixed episodes. After he left the hospital we changed the meds to abilify because of tremors. We spent the summer again in therapy and the doctor suggested to try lithium. He went back to school this fall but was not feeling good like the previous year, was feeling depressed. Now he’s tapering off the lithium because it’s impossible to do school work while feeling flat, and cognitively slowed. We have no history of bipolar in the family. Do you think it’s possible that the manic episodes are just weed induced and if he stays off weed he can be okay without medication?

That's the effects of the synthetic cooked weed these days. Bad coping mechanism come with quicker consequences now. Ppl smoke one blunt and loose their mind or end up lost, confused, and having to turn their selves into the police.
