Flipped his lungs inside out? I wasn't aware that was a real medical condition, or even physically possible. That's gotta be BS.

Weed, it seems, cannot kill you directly. You would have to smoke a whole field of weed to overdose on THC, and the only way you could really die is if you decided to do something extremely stupid like tightrope walking while wrecked out of your skull. In which case, you're a moron and we can blame the death on natural selection rather than weed.
