this has nothing to do with it. you are probably just smoking much more weed in the blunt than you are with bowls pipes.30 min with a bong
45 min with a pipe
2 hours with a blunt
Naturally ive been smoking more blunts lately, i think this may be the solution to your problem..
I drink over 100oz's of water a day...i agree totally with this guy water is the only way
to keep a longer cleaner high
