The RADARS System was developed in 2002 by Purdue Pharma L.P. in response to increasing concerns of anticipated rates of prescription opioid abuse in the United States. In January 2006, the RADARS System became a non-profit operation of the Rocky Mountain Poison and Drug Center, a division of Denver Health and Hospital Authority. The RADARS System continues to grow and evolve in an effort to address new concerns and challenges as they arise.
