Cannabis Dosage Guide

Fatal cannabis overdose from THC toxicity alone has not been documented in the medical literature. The estimated lethal dose of THC is extraordinarily high relative to recreational doses, making lethal overdose practically impossible through smoking or ingestion. However, acute cannabis intoxication can produce extremely unpleasant and frightening symptoms, particularly with edibles or high-potency concentrates. Symptoms of cannabis overconsumption include severe anxiety and panic attacks, paranoia, tachycardia (rapid heartbeat), nausea and vomiting (cannabinoid hyperemesis syndrome in chronic users), dizziness, disorientation, and in rare cases, psychotic symptoms including hallucinations and delusions. Cannabis can also exacerbate pre-existing cardiovascular conditions, and there have been rare case reports of myocardial infarction (heart attack) in young users, particularly those with undiagnosed cardiac conditions. If someone is experiencing severe cannabis-related distress, reassure them that the effects are temporary and will resolve. Move them to a calm, comfortable environment. Encourage slow, deep breathing. Offering black pepper (chewing or sniffing peppercorns) has anecdotal community support for reducing cannabis-induced anxiety, possibly through the terpene beta-caryophyllene which acts on CB2 receptors. CBD, if available, can counteract some THC effects and reduce anxiety. Cold water on the face or wrists can help with grounding. Community experience consistently identifies edible overconsumption as the most common cannabis-related crisis. The delayed onset (up to 2 hours) leads individuals to take additional doses before the first has taken effect, resulting in unexpectedly intense experiences lasting many hours. Community advice for managing edible overconsumption focuses on reassurance, comfortable environment, hydration, and patience, as the effects will eventually subside. Seek emergency medical attention if the person experiences chest pain, seizures, severe vomiting that does not resolve, signs of psychosis, or expresses serious suicidal ideation. Call 911 for any serious medical symptoms. Good Samaritan laws apply in most jurisdictions.
