I find that hard to believe. My first year psych courses (I dropped out like every other time I attempted post-secondary education) included a primer on drugs and how they work. And that was just an intro course. I'm sure he was aware. Which isn't to say it can't happen anyway. I mean, I knew meth was bad joo joo and I still got hooked on it for 8 months. Same with smoking....and fuck me, I'm still drinking booze.Idk? A psychologist isn't the same as a psychiatrist. I think it's totally feasible that he didn't know the ramifications or being on benzos.
