There should probably be a public information campaign about how it may not be physically addictive but be prepared to find that it's insanely habit-forming...
Technically not correct.
While the vast majority of users will not become addicted (and pot is far less addictive than, for example, alcohol, tobacco or crack), roughly 9% of people will develop an addiction. That's more than the 0% that you would need to classify it as 'not addictive'.
(Note that doesn't mean I'm against legalization, just that some of the pro-marijuana claims are a bit overblown.)

ETA: Strange.. the second reference was to a web site called
****. It is a humor site (although their humor is based partly on real information). But for some reason it got censored.
