I've smoked daily (like 1-2g daily) for about 3 years. Currently 4 days sober lol. I'm doing ok atm, a little uncomfortable but using clonazepam & the odd AP mind you my mood has been reasonably stable for a few months now. In the past when I've gone without I have become very agitated, irritable & dysphoric, generally mad at the world. I've lashed out physically at my partner for keeping it from me at times, so I would say that yes he probably does have an addiction & is likely withdrawing (I'm no dr though). They say it's equal to tobacco withdrawal which is probably true, I would say it's somewhat more intense though. I have minimal appetite & difficultly sleeping, some rapid changes in mood & energy too. I'm sorry he's taking it out on you.
