Seriously, the body welcomes it. Smoke too much, it gets tired of it. Take a break, then your body misses it and you get high longer again. Also, I was high, and I got horny as hell for no reason, so guess what I did, well you know what, and let me tell you, when I was about to cum, and when I did, that period of 8 seconds literally removed ALL OF MY HIGH, for 8 seconds, I felt completely sober and normal, as if I was not high, then when my mission was complete, lets imagine that your trying to get a girl pregnant, since this is why we naturally cum anyway, the body seems to just block the THC for a short time to get the job done and get the human race to continue. It was crazy, I lost all my high while cumming, I guess the body can block the THC it if it wants to. Also, if my theory is true, than that would mean that if you were about to get shot, and your adrenaline started pumping, then you would literally lose all of your high, you would be super sober, and you would only concentrate on surviving, since at that moment, the body realized that the THC is not needed, so it blocks the THC and lets you sober up to do what you need to do. What does this mean? It means that the body was literally designed to accept THC. It can identify what it is. Which means that MJ is good and not bad. Which also means that your hormones or whatever that is important to life, if needed, will be used to block the THC like a champ. So yeah, you don;t believe me, try masterbating, and tell me if you dont lose your high in that moment.
