I did it in 9th grade too. And 10th, 11th, no 12th but only because I graduated early and had no 12th. Then I smoked resin in College, then still in Cali, and even when I moved to Colorado and grew.
Resin is just part of smoking, if you have a bong or pipe at SOME point you are going to have to clean it, or else it won't hit. Even when I was growing weed, and buying an oz every week to blaze on top of that. I STILL had resin, because we had to clean out our pipe when it got clogged. So we had a container with just GLOBS of resin, like 3x 1inch globs.
Resin's not a "bad thing" to smoke, it's just "something" to smoke.
