what about stuff like cortisone? It's addictive (you build a tolerance, you have to taper the medicine at the end), but it very far from the issue of heroin.

I am asking in good faith: I used to be prescribed cortisone, and managing the end of the treatment was a pain, I just decided to stop worrying treating my rashes altogether, because that was getting ridiculous. I am wondering if some doctors also threw the towel on that one.
