I disagree. Those under 21 can be fined for attempting to purchase, possesing, and/or consuming alcohol. Why not cigarettes then?

And there is NO law against those under 18 purchasing cigarettes. If a 15 year old buys a pack of smokes they have broken no law. The person who sold them the smokes is the only one who has borken the law.

Yes, but with alcohol the seller can and should lose their license. There is a built in disincentive to prevent sales to minors. Like I said, the reason these substances are prohibited to minors is that they lack the maturity and judgement to make decisions regarding their use.

It is illegal to posesss tobacco if you are under 18, at least in my state. It's a $50 fine, and I THINK a misdemenor, although I'm not sure about the misdemenor part.
