In 2006, 16 million Americans over the age of 12 illegally obtained and used prescription pain relievers, tranquilizers, stimulants or sedatives. That's up from 14 million in 2004. 1 in 20 high school seniors are addicted to use one such drug, OxyContin. This kind of drug abuse led to 600,000 emergency room visits in 2005. In 2002, there were already more deaths caused by opioid painkillers than heroin or cocaine. But don't worry, experts assure us that none of this is going on in Silicon Valley. [WSJ]
