The worlds population would diminish by about 75% and those that survived would eventually become immune.
That would be fucking crazy. Haha. Everyone would be off in their own world. I can only imagine what would happen. Ha. It would be fun if I was the only sober one and I just watched you all :].
people on datura would stumble around trying to reduce their body heat while mumbling and conversing with people who aren't there. the world would become vastly less productive for about 15 hours lol.
If everyone was tripping on datura at once, everyone would have a cigarette. And if you werent tripping off datura, you would be offered a imaginary one. Haha.

the world would begin to pulsate to a simultaneous, harmonious beat. and then we'd start eating eachother's brains!
