Although it was less a "consequence of drugs" episode, SBTB also featured the episode where Slater finds a "roach" in the school bathroom left behind by some fake rock star dude who was filming an anti-drug ad at the time, or something. Real deep.

I think the conclusion of that episode was one of those classic "actors break characters and make PSA" moments.
