Here are a few notes about the hazards and risks associated with lithium. Lithium compounds are regarded as slightly toxic, and perhaps more so than the other Group 1 elements. Lithium appears not to have a biological role, which is not to say that lithium compounds do not have an affect. Some side effects are known. Ingestion of large amounts of lithium results in drowsiness, slurred speech, vomiting, and other symptoms.
Excess lithium poisons the central nervous system.
