Tobacco use should continue to be discouraged through education, proper labelling, and taxation. Making it illegal would inflate prices, encouraging people who to sell it on the black market and encourage users to steal in order to pay for it. It would also take away the incentive to refrain from selling to minors, and put the lives of tobacco smokers at risk, since they would use tobacco of unknown purity. We currently have the same problems with illegal drugs. If they were legal and laws were passed to require labelling, warning, and age restrictions then the sellers would have an incentive to obey the laws and the drug would no longer have currency in the black market.

If cannabis was legalised, less harmful ways of taking it than smoking it could be encouraged and developed. For example, pre-prepared hash cookies and hash cakes could be sold, and cannabis can also apparently be taken in sprays.
