Sorry son, I can see you're 20 ,but I can't sell you cigarettes because the LCBC has declared you're unable to make good decisions regarding your health until you're 21. Oh BTW, didn't you join the military just after HS graduation? 

Nicotine is an addictive poison. It's derivatives are in certain insecticides. Perhaps the board with all its superior knowledge could endorse raising awareness about the roots of addiction and mental illness instead of a heavy handed, bass ackwards decision making possession of tobacco illegal to people under 21. Remember kids if you're 18 and defending our county you can kill and see friends killed, but you're not going to smoke that cigarette until you're an adult at 21.

I don't condone tobacco use...but I completely believe in one's right to choose.
