Being very reactive to things like pills, or weed...I am a light weight and two hits can destroy me for the next 2 hours or so. Since that is so strong one good hit and I’m done so a piece about the size of 1/2 a grain of rice is it. With what I can get out of The Source Turbo, it can last a very long time. But I firmly believe that post-processing is going to be a strong part of the future of cannabis so I am steadily advancing in this area. Pressing rosin is my next venue
