Im not sure how you guys end up wasting more weed when hitting the bong. I usually just pack 2 bowls in my bong at 1 sitting and i'll be so stoned that i wont even need to smoke anymore. But i think it depends on the bong you have, I have like a 1 foot tall crystal clear glass on glass bong with a diffuser. Damn that bong gets me higher then anything else. I probably only smoke about half a gram in a sitting, Except when im with friends then i can expect to run out of weed. I mean i got some friends who dont even have to ask me to smoke, I'll just pass them the bong and offer them a hit. But then there are the other kind of friends i have who just leech off one another. I dont even invite them over and bastards will still come over. To make it worst they wont even bring money or weed, and when your done smoking they'll try to get you to buy them some burger king. Which i dont, i just tell them to eat what ever is in my kitchen which isnt anything cause its always empty.
