I smoke almost exclusively spliffs. I smoke cigarettes too. If I smoke a pure weed joint, I smoke a cigarette after. If I smoke a spliff, I smoke a cigarette after.
I roll J's all day long when I have the money to smoke. For me, it's more about holding a burning stick than just getting high. The way I smoke is just as important as how much I smoke or even the fact that I am smoking.
I enjoy the different flavors, aromas and burning properties of the rolling, pipe tobaccos and cigars of my local smoke/tobacco shops. I read about smoking, I smoke. I smoke a cigarette with my coffee in the morning, sometimes two or three. I can smoke a pack in a day, two packs in a night of drinking or go a week without a cigarette and only be cranky when I'm drinking my coffee.
It's probably pretty safe to say I'm a smoker.
With that said I don't see how anyone could not enjoy the taste of, the burning qualities of, and experience of smoking a spliff. It's how I started smoking weed mind you, the first time I ever tasted marijuana was in a sweet sweet spliff rolled nice and skinny in pure hemp paper. Till this day that's still my favorite way to smoke. Sometimes I put keif in a hand rolled cig and enjoy that with a cup of tea.
Tobacco makes the joint burn slower. It makes it smoother and gives a little precursor buzz to high of marijuana. I love the combination of Nicotine and THC.
Because of the different burning temperatures of weed and tobacco it allows it smoke more evenly and (even though it's probably all in my head) allows less weed to be smoked in between hits and more THC left to the user. Last time I checked in a study a joint was the best way to get the least amount of tar to the greatest amount of THC smoke that wasn't being smoked through a vaporizer. A bong came in third, a pipe 4th... etc.. I won't bother pointing out the study, there are a few that all come around the same conclusion with plenty of other studies showing the exact opposite.
The point is I smoke a lot. Mostly tobacco but I have my moments with marijuana. You could say it's a pretty big hobby of mine. As for seeing smoke go in and out of my mouth, I like that too, sometimes I roll a spliff for that exact reason. Sometime I want to smoke in public... spliff answers the call. Sometimes I want a little extra flavor with some dutch or scottish blend tobacco, spliffing with those makes my beer/whiskey/coffee/tea taste better (something you have to be a smoker to understand).
I guess it's just the way I've been smoking since I started. And btw I have never craved a spliff in my life, a cigarette yes, a spliff... never. I know several habitual spliff smokers that do not turn to cigarettes when they run out of weed.
I don't know, I just prefer it this way, I wish we could all sit down in a room and test all of our ideas on each other.
