Fentanyl A Leading Killer in WI News | June 9, 2023 | 0 | by Morgan McCarthy It’s the latest snapshot of Wisconsin’s fight against fentanyl. A new report from Forward Analytics says fentanyl is the number one killer of people ages 25 to 54 in Wisconsin. More than 4,300 people died from fentanyl between 2015 and 2021, with over half of those deaths coming in 2020 and 2021 alone. The report says there were 614 fentanyl deaths in 2015. That jumped to over 14 hundred in 2021. Fentanyl now kills twice as many young people in the state as car crashes, and kills more older people in Wisconsin than liver disease.
