I had wonderful affects from weed, doing it every day, for about 6 months. Then I started getting tolerance and panic/anxiety problems when I smoked. Now I only smoke occasionally and get nicely stoned each time, although it has never gone back to how trippy/euphoric it was in the first 6 months...I think your mind just gets used to it and it never completely goes away. But yeah..you should be getting high as shit..just take a nice hit, hold it, hold it, and breathe out slowly....and if it doesn't work, stop smoking it..? Perhaps weed isn't meant for you...
