What is the cause of death in LSD and marijuana users?
Interestingly, these two drugs have no known lethal dose in humans. Certainly, if a person took enough LSD or delta-9-tetrahydrocannabinol (the active ingredient in marijuana), that person could die. But the amount of drug required to cause death would be extremely high, and would no doubt differ from person to person, as it does with other drugs. The cause of death is really only an academic question, since there are no overdose cases to examine.
