Making it legal for medicinal use should have been done decades ago, but this wasn't "sold" to the public. Making it legal because people want to get high is exactly the reason it hasn't been- it's a drug that some can't handle. If anyone can justify uses for tobacco, other than smoking/chewing, I haven't seen them but if the government was concerned about health risks, slapping a tiny warning on the pack doesn't seem to have made a difference.
