Generally I agree but it becomes an issue of practicality of such a ban versus the excesses of commercialized tobacco sale. Alcohol is just about sufficiently regulated, if I had my druthers I might change a few things in the american relationship to booze but when you compare alcohol to tobacco you see a clear lack of regulation on cigarettes and self control from smokers. I would ban cigarettes from commercial sale, you could still buy loose leaf, papers filters and a roller and make them yourself but the rollers would have to be sufficiently inefficient and require manual operation, no mass producing your own cigarettes the goal is that nobody should be able to roll one faster than a veteran hand roller and the point of all this is to reduce the possible rate of consumption and therefore reduce the depth of the addiction. Simply put it's too easy to just start chain smoking. Regular smokers routinely smoke half a pack a day or more, something like ten cancer sticks a day, if they smoke outside responsibly that's the better part of two hours lost a day, eventually most will say fuck responsible smoking and ruin the interiors of their homes and cars. Regular drinkers have a beer or two after work or a glass of whiskey or wine a day. I'd let people grow and consume their own tobacco but bar it's commercial sale without license, I'd commission a council on safe consumption and use the data to evaluate how to limit sales and tax various forms of tobacco products and drive smokers to lower consumption and forms of consumption with lower health risks. I'd also probably raise the legal age for purchase of tobacco products.
