I'm one of the only cyclists I know that smoke and get treated pretty badly about it when around other cyclists. In the last few weeks I've been cutting back on how much I smoke a little bit every day and am down to about 4 or 5 a day from a pack a day. I need to quit before it gets too warm and I'm riding a lot so I'm hoping weening myself off slowly will help when I do make the plunge.
When I rode RAGBRAI the first time a guy on my team was an ex smoker and he told me I should wait to smoke until I climb the biggest hill of the day, then just sit there all relaxed smoking as all the people just making it up the hill that can hardly breath look at you like you are the most evil person they've ever seen. I did that a few times and found the responses, and language, to be quite hilarious.
