It really depends on your gear and what kind of room you have. The couple of smokers that I used to hike with took an extra, small-ish water bottle with them. It'd be about 1/3 full of water and they'd just drop the butts into it when they were done. One of them had it figured out to how many packs will fit in X oz container, but I haven't talked to him in ages, let alone being able to recall what that worked out to be.I've considered vaping, but I don't personally think the cost/benefit works out for me. The nicorette inhalers are a lot like vaping, in that there's no burning and no smoke, but the inhalers are also a lot cheaper, don't require batteries, and refill cartridges can be purchased from any drugstore, as opposed to having to be ordered online.
As for burying, I ask you in complete earnestness, what's a better idea? I bury them so that various small animals don't try to eat them. I could pack them out, yes, but I've actually been told by a couple of park rangers that it's not a good idea, due to the possibility of my trash bag igniting in my backpack. (I do a lot of multi-day hiking trips - not a lot of garbage cans or ashtrays available.)
Seriously, if you have a better alternative, please do let me know!
Instead, what we also sometimes did - if we had a fire, they'd simply burn the butts. We generally made fire every night, so they'd just keep their butts throughout the day and the toss them in once the fire's going.
I'm sure there's other means to it... those are just ones I have personal experience with.
In b4 DON'T SMOKE YOU DIRTY FILTHY SMOKER!!
