The Opioid Overdose Crisis
Every day, more than 130 people in the United States die after overdosing on opioids. The misuse of and addiction to opioids—including prescription pain relievers, heroin, and synthetic opioids such as fentanyl—is a serious national crisis that affects public health as well as social and economic welfare. The Centers for Disease Control and Prevention estimates that the total "economic burden" of prescription opioid misuse alone in the United States is $78.5 billion a year, including the costs of healthcare, lost productivity, addiction treatment, and criminal justice involvement.
- Roughly 21 to 29 percent of patients prescribed opioids for chronic pain misuse them.
- Between 8 and 12 percent develop an opioid use disorder.
- An estimated 4 to 6 percent who misuse prescription opioids transition to heroin.
- About 80 percent of people who use heroin first misused prescription opioids.
- Opioid overdoses increased 30 percent from July 2016 through September 2017 in 52 areas in 45 states.
- The Midwestern region saw opioid overdoses increase 70 percent from July 2016 through September 2017.
- Opioid overdoses in large cities increase by 54 percent in 16 states.
In the late 1990s, pharmaceutical companies reassured the medical community that patients would not become addicted to prescription opioid pain relievers, and healthcare providers began to prescribe them at greater rates. This subsequently led to widespread diversion and misuse of these medications before it became clear that these medications could indeed be highly addictive.3,4 Opioid overdose rates began to increase. In 2017, more than 47,000 Americans died as a result of an opioid overdose, including prescription opioids, heroin, and illicitly manufactured fentanyl, a powerful synthetic opioid.1That same year, an estimated 1.7 million people in the United States suffered from substance use disorders related to prescription opioid pain relievers, and 652,000 suffered from a heroin use disorder (not mutually exclusive)

Local Area Info: Barrington, Illinois
Barrington is an affluent suburban village in Cook County and Lake County, Illinois, United States. The population was 10,327 at the 2010 census. Located approximately 32 miles (51 km) northwest of Chicago, the area features wetlands, forest preserves, parks, and horse trails in a country-suburban setting.
Barrington is part of the Chicago metropolitan area and serves as the hub of activity for the surrounding 90-square-mile (230 km2) region which consists of six independent villages including North Barrington, South Barrington, Barrington Hills, Lake Barrington and Tower Lakes, as well as small portions of Carpentersville, Deer Park, Hoffman Estates, and Inverness. The village's motto is "a great place to live, work, and play!"
The original settlers of the Barrington area were the indigenous peoples of the Native American Prairie Potawatomi or Mascoutin tribes, which later divided into the Potawatomi, Chippewa, and Ottawa tribes. Many local roads still in use today, including Algonquin Road, Rand Road, Higgins Road, and St. Charles Road, were originally Native American trails. For many years, Barrington was considered part of the Northwest Territory, then the Illinois Territory.
