I do know that he smokes, I'm not quite sure how often. there's evidence of this in the Mad as Rabbits music video, and theres a picture of ryan smoking also. A few years back there WERE some pictures of the whole band smoking candy cigarettes, though.

It's true. He smokes, and the brand that he smokes is Marlboro Red

Look at the mad as rabbits video....you see him smoking in that and on alot of recent picutres you can see lighters in his pockets....but...he has said he's cutting down.....i hope....(im pretty sure thats a cigerette in his hand below)
