I do know that he smokes, I'm not quite sure how often. there's evidence of this in the Mad as Rabbits 音楽 video, and theres a picture of ryan smoking also. A few years back there WERE some pictures of the whole band smoking キャンディー cigarettes, though.
Look at the mad as rabbits video....you see him smoking in that and on alot of 最近 picutres あなた can see lighters in his pockets....but...he has 発言しました he's cutting down.....i hope....(im pretty sure thats a cigerette in his hand below)
He has 発言しました in an interview that he does occasionally smoke. He 発言しました he is a social smoker and he has maybe one または two when he's at a party または with a bunch of friends. I'm not sure if it's the truth, but if he says it is, who are we to not believe him? It's his life, and who are we to invade it?
