This ends up just penalizing poor people. Cigarettes are addictive. Higher taxes don't magically cure addictions. Anyway, lots of things in the world are bad for you. But it's a free country. If someone wants to smoke and drink and eat a bunch of junk and never exercise, they have that right. There are a ton of "bad" things you could tax, it's an endless futile exercise.

Does this actually even work? My own driving behavior is completely unaffected by gas prices. People still need to go places. It seems to me that convenient public transportation would do better in affecting behavior. If public transport is crap/inconvenient/nonexistent, people won't use it.
