non-smoking in bars will work because there are a hell of a lot more people who need their alcohol "fix" than a nicotine fix. Those that need both will just walk outside to smoke like they do at work and for many, at home.

That most governments think it is perfectly fine to keep tobacco legal - even though they know how deadly it is, yet keep pot illegal - nowing how relatively harmless it is, has nothing to do with the health of people. It has to do with big business and money. Tobacco is a highly processed product that is difficult for the average person to grow and process. Pot is the opposite. Pot is a native plant of every of the 50 states. It grows easily and quickly. Processing it for smoking or for baking takes minimal skills, effort and tools. There would be no way for big business to seriously make the money they currently make with tobacco or alcohol sales, so the government does not want to legalize it.
