Yes, but what about guinea pigs? What happens with them?

I ask, as a few weeks ago I saw a fascinating documentary "Hot Docs: Grass" on SBS on marijuana, mostly about the history of our favourite stuff... there was an awesome scene of laboratory rats absolutely baked on near-lethal dose of resin? THC?... BIGGEST smiles I ever saw on those rats, and they moved sooo sssllllooowwwwlllyyy in their perspex cages.

Now, if I wanna die, I'd rather prefer it to be by merijuana overdose than by anything else...
