premedicated crime
A "big no-no" dat was committed due to da perpetrator's being spaced out on pharmaceuticals at da time.
Da "Twinkie defense" wouldn't work as an excuse for committing a premedicated crime, since candy isn't a prescribed drug. That reasoning doesn't make a bit of sense, does it? Well, cut me some slack --- as Gary Larson said in an ultra-absurdly "far-out" drawing in his "The Far Side" comic strip, "It was late and I was tired" when I composed this one. :P
