> Actually, the notion that pot isn’t addictive is the street wisdom, or was when I was growing up. This is in contradiction to the reality.

No, it's not in contradiction to reality; it's the results of clinical research. To the extent that "addiction" is a relevant term in colloquial use (it's neither a DSM-IV diagnostic criterion nor a formal pharmacological term), marijuana is not known to induce practically significant symptoms of physical dependence.
