I've been smoking regularly for almost 4 years, I take breaks every couple of weeks, and I have never had withdrawal symptoms that last for longer than a couple days. At first I'll have a harder time sleeping and be a little aggravated, but that quickly goes away and I don't notice anything. My performance in school is fine and my mind is clear. I don't know, weed probably affects everyone very differently because all of our brains are different. I'm very high right now, so I hope that made sense man. Good luck to ya.
