Opioids are powerful natural and man-made drugs. Opioids include heroin, oxycodone, hydrocodone, morphine, codeine, and fentanyl. These drugs are used as pain relievers and increase feelings of pleasure, but they also can be addictive. They can be deadly if taken in high doses, taken in combination with other drugs, or given to someone with certain pre-existing medical conditions. The misuse and abuse of opioids is a public health crisis (PDF, 44 KB) in Wisconsin. Addressing this crisis is a priority of Governor Scott Walker and the Department of Health Services.
