i have to disagree with everyone. i think resin is a bad thing. resin lessens the amount of THC that exits the piece in the smoke, making your regular smokes less potent. this is because resin "collects/traps" THC which means that each hit is robbed of precious delta-9-tetrahydrocannibinols...

some dont mind cause they feel like they get it all back when they smoke the resin. the thing is that it also collects a huge amount of carcinogens... not good for your health or for the taste of your bud.

keep the pieces clean for more effective smokes on a regular basis, less carcinogens, and a better appreciation for the buds flavor.
