Speaking from personal experience, I completely agree with your comment. Also, I've seen people move from regular opiate use to not even caring about opiates, on account of (what I assume was) their transition from emotional instability to emotional stability. I think that a large part of prescription drug abuse is due to using them, as you said, as an instant gratification anti-depressant.
