i can make a 1/4 ounce last a month at least by using a vaporizer and only taking 1 or 2 hits per 2 hours per night lol. I often just quit for days at a time too, sometimes i just don't like it. However i used to smoke 3 grams per day, so shit that's well over half a pound a month. My father is a medicinal smoker and god damn, he smokes more than anyone i've ever known, can easily go through a QP in 2 weeks. I'm not sure how he does it.
joints are such a waste, vaporizers really get the most out of your cannabis. Especially my pretty volcano. My dad hates the volcano and only smokes joints/pipe so no wonder he goes through so much. Not to mention rolling 1 gram joints several times a day.
