Do you usually smoke in the same set and setting? For awhile I was smoking every night in my room at night and just chilling. After awhile I was barely feeling high. I believe one night I smoked something like 6 bowls by myself, when I usually only smoked like a bowl or two. And it didn't seem to even help. But one weekend I wen't out smokin' with 2 friends, we pulled 2 gravitys each (normally I would pull like 5 by myself) then we went to dunkin' donuts, man I felt so high. Bein' high in public can really make the feeling a lot better.

Oh, and another time me and my friend got high and wen't to mcdonalds and got some food, that was funner than hell too. Mmm, munchies.
