I can't imagine anyone starts using these sorts of drugs with the intent of becoming addicted. Rather, it's much more likely that they are in a dark place that bends their perspective to the point where they think that starting said drugs is a logical decision. Of course, if your issue is that you are incapable of seeing people who are also suffering from a medical condition[1] as human beings, then I have no words for you.
That's not "pro-drug culture". That's realism that drug use is going to happen, despite the large efforts spent on fighting it, and testing is a fairly easy way of saving some lives.
