You omitted one really crucial thing of what I said:
This is the main issue with most mind-altering things,
The level of mind-altering a substance can achieve determines the extent of this effect. So THC is bound to be more addictive than -say- caffeine or melatonin supplements. That's not "demonizing". Your reflex to downplay the issue in order to defend the status of THC in society is - at least in part - responsible for the issues for people who suffer from an addiction to THC, since their fellow users will be the greatest sceptics if they are told one has gotten addicted. Yet not, because they can't fathom that weed might be a thing one can get addicted to, but because they don't want to jeopardize the legality of weed.
