How many people have overdosed on marijuana?

David G. Ostrow (Medical Marijuana Doctor) gives expert video advice on: What are some potential side effects from using medical marijuana?; Is marijuana a gateway drug?; Does marijuana cause brain damage? and more...

I don't believe that there are any valid scientific published reports of people overdosing on marijuana. Of course one can overdose in terms of having the anticulinary side effects of anxiety and dry mouth and blurred vision and so forth but that resolves and I don't think anybody has ever required to have their stomach pumped or cared for in an ICU because of taking too much cannabis.
