Smoking is not good for your health, but we as Americans are free to make that choice for ourselves. I think that’s the definition of unconstitutional. Banning something like that is only going to make it more widespread and sketchy. Look at the war on drugs and what it’s done, but sure it’ll work this time.

I don’t think “unconstitutional” is the word you want here. There’s endless things you are not free to purchase or choose for yourself.
