That being said, all addiction is mediated by social context, so like I said before, I'm not as big a fan as the distinction between "types" of addiction as you are, but in terms of the question you are asking, we agree.
As I understand it, it is considered to have withdrawals if the person experiences physical symptoms due to immediate discontinuation. Shaky hands, feeling ill, etc. These are symptoms experienced by heavy-chronic users.
Mental, yes. There's a strong "mental" dependency on MJ for many chronic users.
Whether or not it is addictive is certainly not debatable. Millions of people chronically use it, so it is definitely addictive. The degree of addiction is different for each person, as well. Some people can smoke loads in 2 weeks, and stop the next day, without batting an eye. Others can smoke it once and want to smoke it the rest of their life.
