Of course it depends on what you mean by "hard core," but there's absolutely no question that some people can have very significant withdrawal if they smoke enough for long enough--like every couple of hours all day for several years. I've seen it happen to a close friend. (He had already told me that going without pot for two days was one of the worst experiences of his life.) He was stuck with me in Maine, where he didn't have a connection. He had been going through more than an eighth every other day. When he ran out, he just lay on the couch with a pillow over his eyes and rubbed his restless leg incessantly against the other, like a cricket. He wasn't interested in (or capable of) doing anything. I invited him over to another friend's because I knew that friend would have/share pot, but he refused. He said it wouldn't be enough and would just wait until morning. (I had set up a connection for him out of desperation.) Anyone who says you can't get addicted to pot is full of it. As with virtually all drugs, the extent of the withdrawal depends on the individual, but the distinction between psychological and physical is largely nonsense. Psychological changes are based on psychiatric changes, which are changes in the brain, i.e., physical. They used to think cocaine addiction was "only" psychological. Anything that significantly changes your mental/physical state can become addictive. I'm all for the legalization of marijuana, but the atmosphere of one side demonizing it and the other side defending it has led both sides to dogmatic extremes. Defenders pretend that it's ALL good without ANY negatives. Nonsense. The other issue is that many people don't take their pot addiction seriously. Because it's "only pot," they never do anything about it even if it's having a seriously negative effect on their life. My friend is a clear case in point. He has all the signs of a serious addict, including denial and self-centeredness.
