I don't think you advocate smoking, you're just a smoker who was caught on photo while smoking (or right before). Do people see you smoke before/while/after performing? If so, the picture is just showing reality and being "honest" - or in other words: smoking in public always advocates smoking in a way. If not, forget what I am saying. (I smoke 3/4 cigarettes a day and my picture shows me smoking. People see me smoking in public, so this picture is just ME, 3/4 times a day...)
You are btw also advocating scarfs, music equipment, the metro and orange sunglasses ^^ On the other hand it is your right to be seen here as you want to. I just think it would make you (with all respect) "a bit fake"... Love your music! (Sorry for my english)
I don't want my default pic to feature me smoking. I don't think I should advocate for smoking and I've tried to get these pictures all taken down for that reason. People DO seem to like this one though eh?
