The answer is simply NO! There has never been a documented death from the use of marijuana. There are instances of people getting “paranoid” and they start to think they are dying, but in actuality they are not. This happens most often with inexperienced smokers who simply smoke too much.
“If you mean can they overdose and die from marijuana—the answer is no, its not very likely.” http://teens.drugabuse.gov/national-drug-facts-week/drug-facts-chat-day-marijuana
“And since marijuana smoking can’t kill outright — there’s no such thing as a fatal marijuana overdose — short-term use isn’t deadly.” http://www.webmd.com/smoking-cessation/news/20030918/marijuana-smoking-doesnt-kill
“There has never been a recorded lethal overdose in humans from the use of marijuana in any form. The best evidence on lung cancer comes from Dr. Donald Tashkin of UCLA, who is the leading researcher on that topic. His latest research shows that marijuana smokers actually have a slightly lower incidence of lung cancer than people who do not smoke at all.” http://www.answers.com/Q/Can_you_die_from_smoking_marijuana
