I've been smoking for about 10 plus years now and I never really cataloged how much I smoked a day. When it comes down to flower, I would say around 2 - 3 grams, sometime less when I'm by myself. If we are talking about CO2 oil cartridges, I would say .05 to .1 a day. I am currently vaping oil and my wallet has definitely thanked me for the switch. I still smoke flower but I try to limit it to when there are plans.
