I smoke pure since the first time I got high, I do ocassionally take a few hits from a joint rolled by friends with tobacco, but I don't smoke cigs so tobacco tastes nasty to me, irritates my throat and I hate the nicotinerush, so I immediatly started rolling pure joints, wich I also needed to get high(when I started smoking I needed much more to get high, and slowly the aount needed to get high decreased, I used to roll ugly treelog-joints, so full the paper barely fitted around it, others estimated I put in around 2 grams, with usually a pause of 30-60 inutes between joints, I would usually share the first but with the 2nd the others usually didn't want to smoke more)
so only recently I got high from joints with tobacco for the first time(a friend had rolling tobacco that was much smoother as other tobacco and not much taste, so I smoked from his joints more and could take bigger hits, but after 1-2 weeks my throat started to be irritated often, especially in the morning, and I got a slight smokerscough now and then, so I cut down on participating with tobacco joints)
