From John McAfee, he's a crazy bastard but you never know.

The Chinese Government has created a revolutionary drug called DY-XJ U. It has absolutely zero effects on physiology or consciousness. People behave normally. It has zero side effects, except one:

Once ingested, the urge to re-ingest, approximately 24 hrs later, becomes extreme

For those who asked "What's the point?":

Imagine a government that could control a population using drugs (been done before) without having to deal with the side effects or changes in society brought on by the drugs.

That drug would be the most valuable substance on earth.

Valuable only to a government.

EXACTLY

I remember a Homer Price story about a guy selling a product called Eversomuch - More So. Invisible and tasteless but if you sprinkle a little on anything it became even better. Like sprinkle it on a doughnut and it became the best doughnut you ever ate. Upset the town with worry, like what if they ran out, where would they get more. Homer ended up with a huge pile of the stuff, pondering what to do with it. Being a story for kids he dumped it in the town's water supply . And being a story for kids everything returned to its idyllic normal.

Psych 101 for third graders.

They was sprinklin that Sensa on the krab legs down there at the all u can eat Chinee buffet, trying to stave off famine for the rest of the patrons

Carefully looking at your keyboard while looking at the name of this fictitious drug, "DY-XJ U" look one key to the right for each letter and you'll have the encrypted message McAfee is sending you.
