Id rather have them doing none of those things, but that isn't possible, but why then just let them do them all? Many less people would die and succumb to addiction if alcohol and cigarettes were criminalised, but unfortunately they are so in built with our culture now that it's impossible to do that, the best we can do is offer advice, help and guidelines. To me is seems backwards to legalise weed when we should be encouraging people not to use any of these substances. True, no one has died directly from an overdose weed, it isn't fatal, but smoking it can still seriously damage your lungs and increase the risk of lung cancer, and it can indirectly cause deaths either as being used as a gateway drug, or by the abuse of the substance in dangerous scenario's such as driving.
