Here is what I have learned on this thread:

1. Smokers rarely if ever litter by tossing their cigarette butt out the window or on the beach. However, they do regularly pick up other trash that they come across.
2. The harmful effects of cigarette smoke (including second hand) is no different than burning sugar cane, charcoal and bon fires.
3. The surgeon general's findings about smoking are not nearly as valid as those that have been provided by the good folks at the tabaco companies.
