I'm not going to go into a long rant on the PROs and cons as this will be deleted. For the record i am on the PRO side but i definatly have to argue with the death stat.
The 0 deaths from pot annually is 0 overdoses which would be next to impossible to do as you would pass out ong before you could smoke enough to kill ya. But a joint is just as hard on you lungs as a cigarette. Not much of a concern for an ocasional smoker but you cant right it off as a benign. Also smoking moldy bud is directly attributed to lung infections. I'm sure there are people who have died as a result of thier pot smoking its just not something thats easily tracked
