On the acne thing, is it only drug users who experience it on the back/delts etc?
I am drug free but in the last couple of years I notice that my thighs, along the front and sides, tend to breakout at times. Nothing major, just a couple of spots now and then. I was lucky in that I never really got acne or spots at all on my face or anywhere else, even when I was a teenager, so I don't think I would just start getting them now on my legs at this stage. Could it be from friction against clothes or something?
