Oxycontin addiction is caused by long term intake of Oxycontin ®. Oxycontin ® is the brand name for the time-release formula of Oxycodone, a narcotic analgesic for moderate to severe pain. Oxycontin, sometimes referred to as “hillbilly heroin,” has a high potential for abuse and is sold and traded on the street. The high street value directly relates to the increase in Oxycontin-related thefts from individuals and pharmacies.
