Can someone overdose on marijuana?
If you mean can they overdose and die from marijuana–the answer is no, its not very likely. But they can experience extreme anxiety (panic attacks) or psychotic reactions (where they lose touch with reality and may become paranoid). And people can and do injure themselves because of marijuana’s effects on judgment, perception, and coordination. For example, marijuana affect the skills you need to drive (e.g., concentration, reaction time) so people can injure themselves and others if they drive while under the influence.
