Man, that sounds false to me. I don't even know how you could go through more than a gram in one sitting. Even with shwag, a good 1/2 gram bowl is more than enough for most people. In my life, I have honestly only smoked maybe 2 bowls MAX per sitting. I don't know if i'm considered a lightweight or what, but all my other smoking buddies(15+) are always content with one bowl, and they only light up again about 2 hours afterwards.
