Booze, tabs and dope

It would seem like common sense to assume that cannabis is more dangerous than tobacco and alcohol as these are legal while pot / dope etc is not but this is not the case. Thousands more people die every year from smoking and booze than smoking pot. It is unclear why the government refuse to mae cannabis illegal apart from the old argument that it encourage people to try stronger drugs because they could make money out it instead of drug dealers and it is also an effective painkiller so there is call for it to be available to make it available on prescription. The alternative would be to make cigarettes and alcohol illegal but then a black market would spring up and the state would lose a fortune from taxes.
