There is technically no such thing as a marijuana overdose. The most common, and closest thing to an "overdose" of marijuana is puking or even just a headache from it. It is nearly impossible to die from smoking marijuana, you must smoke atleast 100 pounds in one day, which is impossible for one human to consume because they will have thrown up thousands of times before that and had huge headaches to even continue smoking marijuana. So there really is no overdose of marijuana resulting in death.
