Last year I smoked 1.2 grams (about a joint and a half) per day on average. I can specify that because I was in Florida a similar length of time last year and know exactly how much I took with me and consumed in a given period over several months. Quit smoking and began vaping last April and it obviously cut my consumption, but by how much? Took 45.5 grams (13/8ths) and stayed 64 days. Only vaped 43 grams so 43 into 64 = .671 grams per day. By vaping I've cut my long term marijuana consumption in half!
