I see. So it was the fact that he smoked marijuana that killed him, not the fact that he made the incredibly dim-witted decision to drive a motorcycle while intoxicated?
Well, he wasn't killed. But you're mixed up. Forget the motorcycle. He made the decision, while intoxicated. And that's the problem with being under the influence of booze or drugs, you make the wrong decisions. Sometimes, fatal ones. The Darwin Awards would be a pretty short list, without that factor.
