I'm a smoker and I never throw a butt anywhere. I always field strip it and put the butt in my pocket or in a garbage can/ashtray. Each cigarette butt pollutes 12 gallons of water, that's just not cool man! They look like crap laying all over the place nobody denies that. So just STOP PUTTING THEM IN THE WATER. Do you throw them into a lake too? They are not getting torn up there that's for sure hust sitting around looking like ass polluting the water.
AND: Camel filters are made from cotton, so they'll go away pretty quick (the chemicals still pollute though) Marlboro filters are made from some type of fiberglass they should not go in the water at all.

As far as making smoking on the rivers illegal I was in new york for the first time a year ago and was shocked that you can't smoke in a bar...!@#$%^& smoking nazi's :rolleyes:
