I've smoked a pipe (no, not crack
) and cigars, but since my grandpa (WW2 rockstar vet that he was) lost ALL his teef to chewing plugs before I turned 10 - that's one thing I've never so much as tried. Then when I got to BCT and there were guys who'd been chewing that fiberglass enhanced chit who had their gums carved out down to the bone to remove it, and they were only 18-20; that was affirmation that I'd made the right choice.
I've been tobacco free for a couple years now. I do still like cigars and pipe tobacco, but I've decided I have enough else wrong with me that risking mouth or lung cancer on a hobby just isn't wise.
