Cheap Chinese-made high dubbed 'US$5 insanity' kills dozens in Florida and makes users psychotic
A new synthetic drug, known as flakka, has led to at least 34 deaths and is spreading quickly

As drugs go, it's dirt cheap, potent and deadly. And it creates surreal, pitiful scenes like this: a man running down the street buck naked, fleeing from imaginary dogs.
The addictive, synthetic Chinese-made drug known on the streets as "flakka", or gravel, has killed dozens of people in Florida, and its popularity is spreading fast. Also known as "US$5 insanity" in allusion to the price of a dose - the formal chemical name is Alpha-PVP - the stuff is similar chemically to "bath salts".
Particularly hard hit is Broward County, a touristy area of south Florida, just north of Miami.
"Broward is much like ground zero for flakka or Alpha-PVP," said Heather Clark of United Way, a charity that is trying to raise awareness of the dangers of the drug.
People generally smoke it, but it can also be injected intravenously or "vaped" - inhaled in vapour form.
"It truly is a very dangerous drug. It's not recreational. It's not something that you can take without adverse side effects," Clark said.
