Hi all, been a long time since I've stopped by...Well to answer the posters question scientifically, its because you are now a regular smoker. The endorphins in your brain that the cannaboids effect have been depleted due to daily use. If you want the original "buzz" that you once obtained, take a break from using. This will allow your brain time to build back up the endorphins. Take a 60 day break and then smoke some exotic..You will notice a bigggggg difference!!!
