From what I've read on the site below, there actually can be some physical and psychological withdrawal symptoms after discontinuing weed, particularly for regular or heavy smokers. But they're not permanent, and theyr'e not like the sick withdrawal from a hard narcotic. Two of the common ones reported are apparently "anhedonia," or lack of ability to feel pleasure, which essentially is like depression, and lack of appetite. I always trust what Erowid has to say. They've gathered this info from thousands of people and years of research.

birdgirl73 Reviewed by birdgirl73 on . Effects of suddenly quitting I have noticed that whenever I go through a period of smoking up on a fairly regular basis for a couple of weeks, and then suddenly stop, my appetite and sex drive go down by a lot. Obviously when you're stoned, both of those things go up, but for several days after I stop, they are far below what they would be before I even tried pot. Does anybody else go through that when taking a break from smoking every day? Is it a form of withdrawal? Rating: 5
