I think weed is at its best when smoked 1-2 times a week. any more than that and it just starts to lose its magic. I know if I smoke it everyday i'll just be lethargic as fukk. if its an everyday thing, thats when it starts to effect your motivation to do things. basically, if you're a daily smoker, you're doing it wrong 
ideally, its best to smoke no more than 2 times a week
