Heavy, constant, medicinal smoker: about 1 to 2gm a day, when i have supply.
Do you mean 2gm THC or is 2gm the weight of edible (including gummy, chocolate and other good stuff)?
Thats with extreme efforts at conservation, i dont smoke joints. I use either an Allihn condenser or a small hand pipe (which isnt as efficient) but neither burns except when im sucking on it.
