Hallucinogenic agents include lysergic acid diethylamide (LSD), psilocybin (“shrooms”), and mescaline, which is the active ingredient in peyote. If ingested in very large doses, seeds of the morning glory plant (Ipomoea violacea), leaves of the plant Salvia divinorum, and nutmeg (Myristica fragrans) may also cause hallucinations. Of these agents, LSD is the most potent hallucinogen.
Signs of hallucinogen ingestion in pets include a severely altered mental status, disorientation, stumbling, dilated pupils, excitation, depression, bizarre postures and movements, and vocalization. Signs may last eight hours or longer. Though some pets may need treatment in a hospital, death is not common following the ingestion of these substances.
