Almost all of my trail experience has been with those who partake in the left handed variety - I have no problem with that

. I can think of only one fishing partner who smoked cigs, and he was extremely cognizant - he snuffed out his smokes in liquid, then packed the butts in a zip-lock bag - did the same when fishing on the ocean, so I have to commend the guy. And then he quit smoking, so all the better.
Over the years, I have picked up many cigarette butts while hiking wilderness trails, and carried them out in a zip-lock bag - too bad it is necessary, but I will always carry them out. And yeah, I think it would be a great idea for cig co's to buy back the butts, at $.05 or more.
Cheers.
