Crazy that you're getting downvoted for this. I smoke occasionally, but used to smoke daily and had to quit cold turkey for over a year. I now (almost 3 years since I first stopped cold turkey) refuse to have any marijuana on me and only smoke on the occasion that I'm out with friends and it's offered to me. That ends up being about one toke a month. Irritability and bad mood for chronic smokers when they haven't smoked enough to get withdrawals is common enough (anecdotally from my own experience quitting and seeing others around me struggling with it as well).

Especially if someone has quit and finds the smell off-putting or doesn't like to be around people who are either constantly baked or very irritable, this point of view is perfectly valid and adds to the conversation. Don't downvote just because you personally disagree.
