What to do... again

my friends and i have decided that we are gunna give up pot. now the only problem is my friends and i love pot so much and i don't really understand whats so bad about having pot as a hobby. like i understand smoking in bad for you and i understand that when we smoke we sit and eat alot of times but honestly whats so wrong with that. lol i don't know i having a hard time with this decision. the only bad thing i can think of is the price. but if it was legal then it would definatly be cheaper.
