Hmm, and where did the volunteers for this study sign up?

Seriously, though, what were the symptoms? I'm sure the participants didn't actually go schizo after smoking the weed. Maybe they just got paranoid, or had weird things going through their head because, well, they were taking an illegal drug with doctors around monitoring them! Not exactly an everyday situation. These are probably randomly-selected people who don't smoke pot. If it's your first time ever smoking pot, and you're in a strange laboratory with people examining your brain and shit, and you don't know what's going to happen to you and the doctors don't even know (that's what they're trying to figure out after all), then yeah, I could see how you might get a little paranoid and freaked out in a way that they could measure with brain imaging.
