I know a few people that get anxiety from marijuana and I have a few times, mostly when I am nervous when I feel I may fail a drug test but if you have the money for it, you work hard and everything is going your way, why quit? I know a lady who smokes one joint everynight and has done so for about 20 years, she is about 34 now, very pretty and wants to quit. Everything is going her way, she has plenty of money, owns a nice home, has a husband, and is in good shape ect. I can't see why someone would even want to quit, and it costs her no more than a pack a cigarettes a day, about 3 bucks for a fat joint of midgrade.
She has said she wanted to quit but everytime she does she stops for a day or two she pops percocet which is obviously much worse.
