You are posting in the addiction forum where the focus is breaking free of the addiction. Of course you are going to hear that doing drugs is bad and you should quit. I don't know you, but I know me. Drug and alcohol use was interfering with my treatment. My current list was a lot shorter than yours, so I assume your drug use is probably interfering with your treatment. In my younger days, I had a list that long or longer and I handled it okay to a large degree. I would also have been pretty defensive in an anonymous forum, especially knowing a lot of the people chastising me were jonesing for the very same drugs. But I wasn't being treated for bipolar disorder at the time. You are asking your pdoc to hit a moving target; how can the doc know whether the results since the last visit are from what was prescribed or from what you self administered? Who bought it is irrelevant.
There is the whole issue of short term and long term health risks but you don't seem interested in hearing that right now, probably because you know that speech by heart, so I will spare you that one. That doesn't mean I condone what you do either, though you don't need my approval.
