Yeah, heavy users of MJ who stop using suddenly are gonna have some mild issues. This is not surprising, considering that people who use MJ very heavily tend to do so do deal with unresolved emotional issues or untreated (or untreatable) mental illness, and when they stop relying on MJ to cope, they have to deal with their emotional issues and the loss of their accustomed crutch.
I experience minor withdrawal syndrome when I stop cutting myself with razor blades daily. This does not mean steel is addictive. It means that the sudden loss of a thing that enables one to cope with or avoid coping with emotional/mental problems on a daily basis is going to cause some things, like anxiety, depression, and insomnia.
I smoked a couple cigarettes, and I became addicted. I said hm, this ain't a great idea. And I kept smoking them. I smoked a couple joints and I said hm, this ain't a great idea. And I stopped.
Not everything that people use to maladaptively cope with emotional problems is horrible and dangerous in and of itself. As for addictive, there's clearly a spectrum, and MJ is right up there in terms of danger with intimate relationships, razor blades, Red Bull, the internet, tv, coffee, exercise, sex/porn. All of these things, when relied upon routinely and maladaptively for help coping with emotional difficulty, can cause some serious problems, and all can lead to mild withdrawal symptoms like anxiety, insomia, and depression, when they are suddenly stopped.
None are generally considered dangerous or addictive.
