“A surprising number of people so afflicted [with bi-polar disorder] have independently made the discovery that cannabis has improved their conditions, whether the mania or depression. It may also reduce side effects of other drugs used in its treatment, such as Lithium, Carbamazepine (Tegretol) or Valproate (Depakote).
