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.
BTW - One of the reasons it was "COOL" for 14,15yr olds to smoke is because it is giving the middle finger to authority.
My first response to reading this? No @#%^ Sherlock!!!!
By 19-20-21, The only cool part about smoking is standing outside striking up conversations. Other than that, it's expensive.
I just smoke an occasional cigar myself.
