I have a nephew who I'm certain smokes marijuana on a fairly regular basis. Maybe daily. He's fifteen. I gotta figure he gets it from someone at school. Maybe he takes some from his dad, who also smokes daily. Anyway, every once in a while this kid totally loses his mind. He gets angry, starts screaming, throwing things. He's not small. He broke their sliding glass window and half of the mugs in the house. He has broke things in his room, shelves and a radio that resulted from his taking anger into his room and letting fly. My sister always told me he was suffering from an management problem, duh. But I talked to him last week and he confessed that these anger flashes come on when he runs out of marijuana. He says he can stay focused and keep steady when he has a little bit to smoke every day, but when he runs out, "I wide open," he said, sweeping his hands from the center of his face outward as far as his arms would reach. "I can't do nothing." He looked at me with pleading eyes. Has anyone heard of THC-withdrawal induced anger? Is he telling me the truth?
