It can be habitually addicting, meaning it can be easy for one to form a habit out of doing it, but it is not physiologically addicting and that is just a fact. I've seen so many credible sources stating this along with me literally asking my doctors and they all tell me the same thing. Mentally addicting, yes, but not physically addicting. But I suppose one could consider using the term addiction then. But like Sogeking said, to compare marijuana to cocaine, crystal meth, and heroin is laughable since there is such an apparent distinguishable difference.
