“One in 10 Americans admit taking a prescription drug they have not been prescribed, and a quarter of those people have used them just to get high, according to an ongoing Reuters/Ipsos poll. While about six in ten Americans who used another person’s prescriptions did so for pain relief, a fifth took them to sleep or to manage stress and anxiety, the poll showed. Pharmacies in the United States dispensed more than 4 billion prescriptions in 2012, according to IMS Health, a healthcare research firm. The poll indicated it is not difficult to get hold of such drugs even without a prescription.”
