If you can be "psychologically addicted" to anything, then why label marijuana specifically as "addicting"? We don't label wintergreen mints as psychologically addicting, even though some people will routinely crush a bag of them in one sitting. It seems that we're misattributing the human, habit-forming parts of ourselves (or possibly our need for pleasure) as a negative-characteristic of marijuana, and I don't think that's being genuine to the problems.

Articles like this only further the demonization of marijuana and give cause to ban it.
