I do not smoke. Between the ages of 14 and 27 I stayed high everyday. Wake up smoke, break smoke, lunch smoke, smoke break, smoke smoke smoke. I sold weed to afford the habit in highschool and early twenties.
One myth I have read on this post. Marijuana does not make you "permanently" stupid. THC coats nuerons causing them to send messages slower to the brain. After diminished use this goes away.
Alcohol on the other hand Kills brain cells, point blank.
I am fully for the legalization of marijuana, although I don't know if I would smoke it if it was. I still see it being illegal pointless effort of congressional lobbyist as the partnership for a drug free america (Anheiser-Busch and Phillip Morris)? Also feeds lots of money into our legal system.
