I've always thought of using cigarette filters inside of joints. Would that work?
I never tried it. I did travel with some hippy
who was convinced that the filters were dangerous, so if I'd try to light up a cig he'd break it, mix the tobacco with some hash and roll a joint :hippy:. I didn't bother arguing with him.
To return to your point: usually a filter is just there so that you have something on your lips that isn't burning weed. I've seen Europeans use tobacco (hand-roll type) for the filter. Some don't even bother with a filter and just throw it away near the end
