You’ve gotta strip it first. When my buddy came back from the military he taught to roll it around in the fingers until the remaining tobacco falls out, then the trash goes into the pocket until a bin is found.

Although, there’s not a class on that at all. I did my fair share of littering as a smoker. I still feel shit about it, which is why I bring my picker upper stick and an empty bucket with me on walks. It comes back full every time. Water bottles everywhere.
