yeah the only people i know that smoke green smoke bush buds exclusively. I always 'spin' my bud, although i usually only put half a cigarette to 1.4 - 1.6g. Depends on the bud though, if its some beautiful skunk i really don't like tarnishing the high with the heavy feeling nicotine gives you so i'll only add around a quarter of a cigarette to 1.4 - 1.6g. The reason I do spin my bud for all the Americans wondering why people do it is not actually for the extra cones, but instead for the slight smoothness the tobaccos adds to it, which makes taking bigger hits easier without having to cough. I will literally cough everytime if the mix is 100% green which can make it an overall unenjoyable experience.
Although, i'm almost certain that the adding of the spin is what makes us aussies such fiends because it adds a nicotine element to the smoking experience and i'll even go as far to say that a completely green session sometimes wont even hit the spot. I'll get stoned, but i won't feel satisfied at all, this is definitely nicotine dependence. Ah well.
