I skin-popped some diacetylmorphine hydrochloride, and I have a small, irregular, somewhat itchy, flat, red rash around the injection site. I used a micron filter and I sterilized the injection site with rubbing alcohol.
It's not particularly bothersome, because its not painful, not raised, and it's pretty small.
