When I smoke pot I use a bong 85% of the time......but I'm not sure whether it is the best way besides a vaporizer to conserve weed. Different studies have shown different things: some studies say that bongs filter as much THC/cannaboids as they do tar, meaning that you would have to smoke more weed to get an effect, this is not good for conserving weed. Other studies say bongs produce effects quicker because you can inhale more smoke at once. Which is true? I myself am not sure. Sometimes it takes the bong more hits than needed, other times it produces effects right away from one good hit. Same goes for pipes......sometimes they work quicker than bongs and other times they don't. Which is better at conserving weed: a pipe or a bong? Will using a bong help conserve weed or does it take more weed?
