I work in mental health and was surprised by the amount of people in the field who believe marijuana is part of the problem, not just a symptom of it.
I've been in mental health institutions and it's amazing how many people will blame drugs in order to completely ignore the deep life/social problems that people face.
That's basically the whole point of the mental health industry. They turn social problems into druggable, profitable, "medical" problems - while also undermining any movements for social progress.
This is precisely the kind of situation that is re-entrenched by blaming the problem on weed.
That's the real danger of pseudo-scientific articles like this.
