Zhukov, they make drinks, pills, foods, candies and i think patches and shit you can take instead of smoking it (although they prolly dont have a lot of that stuff in australia). but do whatever you feel comfortable with. Personally, if I have a headache -- although its not really quite a migraine -- and I smoke I usually feel a lot better.
GW lives in Oregon (I think) where its practically legal. Where I live (california) if you get caught with under an ounce of weed you just get a misdeamenor charge which is like an 80 dollar fee -- a slap on the wrist.
Also elx, you're an idiot. Just shut up. I hate you. You're so stupid. Most of the stuff you listed has nothing to do with pot but with selling/being an idiot on it. Also "some of these kids?" Ok. Smoking weed and selling it isn't the same thing, yet you are wiling to consider them as a whole and transfer the penalties of the whole onto a smaller part which doesn't carry the same penalties. This is called a fallacy of division.
"GW i should warn you that you shouldn't even consider buying a gun. Many people who have guns end up going to jail for possession of an unlicensed fire arm, concealing a weapon, farting in public, and murder I. Some of these kids end up serving 10-50 years in jail, maybe even life or the death penalty! These are some things you should consider."
