I became temporarily immune yesterday. I had been toking about every 2 hours (in small-moderate amounts) since morning and finally at midnight when I couldn't get to sleep I started smoking some hash. I smoked and smoked while listening to music and got to the point where I realized after about 8-10 tokes nothing was going to happen and I was just wasting my stuff. and I didn't just get a mild buzz, there was absolutely no effects.
