I've used most kinds of tobacco at one time or another...
Started smoking cigarettes in the military...quit after about 5 months as I found it rather pointless and I didn't really enjoy it, it was more of something I just did to get out of work for a bit and BS with some of the guys.
I chewed in the military as well. Did it at tech school, passed the time in the dorms with a dip in (broke a couple of the rules in the dorms...) again it was purely social. Quit after tech school.
I occasionally will smoke hookah with a few friends, but it's a pretty irregular thing. I'm not a huge fan, but I don't hate it either.
I've used snus. I kind of enjoyed it, and I may buy some more in the future...
I use snuff in the autumn/winter. I also talk my friends into trying it, most of them like it. I have to thank ReplicantArgent and ScottishSmoker for getting me into the world of snuff. I'll be ordering some more of it soon, seeing as its starting to get to be that time of year again.
I have a decent collection of pipes, and I usually smoke them in the cooler months. My piping has been kicking up again, and I like it
Been smoking cigars for about the last three years. Had a lot of fun with it, met a lot of good people through it, one of my better decisions of things to do in the last three years. I don't intend to quit, ever. Although my smoking has dropped a bit since I've gone into the military, I still have a nice stockpile, and I very much enjoy the hobby.
