Haldol (Haloperidol) is an anti-psychotic used to treat psychosis, confusion and delusions. It is also widely used as a behavior modifier as well as for turrets syndrome.
Depakote (Divalproex sodium) alters chemicals in the brain that are involved in seizures, mania (bipolar included) and migraines.
Hopefully that answers your question. As for the side effects of bipolar not much is noticed. The research I had the doctors focus on was Schizophrenia, which isn't a good thing to have while doing ANY drugs... Including many OTC medications.
As for saying I'm wrong about marijuana being healthier then tobacco.

Shows that they are around the same, and MUCH less is being smoked per day on daily marijuana users.
