I don't smoke for obvious reasons. I really can't understand why anyone would smoke. My opinion.
I would forbid all alcohol and other drugs (including cigarettes), if I was in control of my country. They are products of our society that are not needed, they only pose a threat to everyone.
The U.S. banned alcohol once. No one was about to give up drinking, however, so many people obtained illegal alcohol which made the U.S. lose alot of money to the Black Market (don't ask me how, I'm basically regurgitating what I read in History class). Supposedly, even officials were drinking illegally. :/
Lesson learned here: Money moves everything.
Alcohol and tobacco are really adult products. I guess a drinker or a smoker would call it entertainment... (I don't drink or smoke, so I can't really tell you that) Since Senators, Representatives, Governors, etc. are adults, its safe to assume that there's at least a few of them that do either or both. Since they're in power, they have the choice to ban the stuff. Of course, its not as simple as I'm putting it...
Alcohol doesn't cause as much damage to others as much as tobacco does, however. I also mean tobacco as in smoking tobacco. When you're walking down the street and have to walk in front of a smoker, you'll usually have to breath in the smoke they're emitting- That's where its dangerous for others. Alcohol, on the other hand, is only dangerous to others when the drinker has had more drinks than he can tolerate (drunk) and even then, the drinker may not even be violent or a threat to anyone (unless, of course, if he's driving... Then he's a danger hazard with impaired vision!)
...And I've rambled on too much. That's alot of BS I pulled off! n_n This must be a new record for me!
