The pain medicine, oxycontin came on the market in 1996.
At that time the manufacturer assured the medical community there was no evidence it was likely to be addictive.
Maine Attorney General Janet Mills stated "When in fact, we find the opposite is true. It is highly addictive, highly habit-forming. We know that people hooked on heroin and those kinds of hard drugs, three-quarters say they started with prescription drugs."
Mills said it's possible the drug companies used deceptive business practices and may have violated Maine's Unfair Trade Practices Act.
