Conscientious objector

I have never used any drugs of any kind. I initially had no moral objection to it. I just didn't have a supplier that I absolutely trusted not to get nabbed and sell me down the river. At some point though, that blossomed into a superiority complex since I was able to harangue others with the fact that they lack my self-control. Not to mention, I'm the smartest person I know. I don't use illicit street drugs. Coincidence or causation? So now I'm the guy that shows up to a party and demurely declines a hit.
