Bull crap, you’ve never met some of my high school friends.
Yes, people can become mentally addicted and use pot constantly until they neglect other things. It also happens with video games, porn, facebook, food, shopping etc. Should we ban everything potentially addictive?
The difference from other drugs is that it is only a mental addiction and once they quit, is never permanent damage and the impairment stops almost immediately.
Abusers of alcohol and Rx drugs become chemically addicted and have permanent damage after they quit.
