I don't claim to have evidence and never have. Don't think I was putting an argument one way or another, just hoping that those that did backed them up with evidence. The point you made, or implied, was that because the coroners verdict said cannabis killed then your mate should be dead. My retort was that smoking doesn't kill everyone that uses it. In other words, just because there are many that use cannabis doesn't preclude it from being the cause of death in this case. Just as with alcohol, my drug of choice if you like, there are plenty of people that drink and get on with their lives yet there are others that become dependent on it!
Seems with cannabis use (and this isn't aimed at you) that those that take it recreationally seem to feel threatened when stories like this come out and then seek to justify if with stories of people with debilitating pain using and, as in the case of Midnight Rendezvous, stories of its miraculous properties against cancer which he has so far failed to back up. My view is that I have no complaints if it is used medically and under prescription but at the moment that isn't allowed. Equally, if it was made legal then maybe there would be more control over its strength and more importantly its distribution.
The only evidence I can find is of the mentioned report which names one women who seems to be the first ever to have died of cannabis toxicity.
Control it's distribution if you want........... Then see all the redundancies come up at the Mars chocolate factory.
