Prescription pills blamed for 'Pharmageddon'

Sarah Shay and Savannah Kissick were school friends in Morehead, both addicted to an array of perfectly legal drugs. Sarah died in 2006, at the age of 19. Savannah followed three years later, aged 22. Both victims of an epidemic of prescription pill abuse sweeping parts of America. When their mothers reel off the names together, they make them sound like weapons.

"Xanax. Klonopin. Oxycodone. Hydrocodone." Earlier this year, the White House described the epidemic as the country's fastest growing drug problem, accounting for more accidental overdoses than the combined total from heroin and crack cocaine in the 1970s and 80s.
