Opioid Trends


What are opioids?

  • Opioids are a class of drugs used to reduce pain
  • These include pain relievers available legally by prescription and heroin

Prescription Opioids

  • Prescribed by doctors to treat moderate to severe pain, but can also have serious risks and side effects
  • Common types are oxycodone (OxyContin), hydrocodone (Vicodin), morphine, and methadone, and synthetic opioids like fentanyl
  • Fentanyl is a synthetic opioid pain reliever that is more powerful than other opioids.  It is normally used to treat severe pain like pain from cancer.


  • An illegal opioid
  • Natural substance that is processed from various opium poppy plants
  • Can be white or brown powder, or a black sticky substance known as black tar heroin
  • A common street name for heroin is smack

  • Opioids can be highly addictive


  • In Rock County, it is estimated that the opioid epidemic costs as much as $50 million in lost wages and productivity, healthcare costs, costs of incarceration
  • Estimates of the financial costs of the opioid epidemic include lost earnings, productivity, tax revenue, as well as costs to the healthcare system, criminal justice system, social service agencies that stem from opioid overdoses and deaths
