Is lithium a stimulant

Answer 1

Yes, but only within a specific therapeutic range of blood plasma concentration, and only in patients with psychological disorders. For most healthy people, even reqular exposure to dosages of lithium above 600 mg/day will not produce any psychological effects. This is a strange and unique quality among psychotropics; however, this is not surprising in light of the fact that no one really knows lithium's exact mechanism of pharmacological action.
