In an effort to address the growing threat of dangerous synthetic drugs in Illinois, the Senate has passed legislation to more strictly regulate xylazine, a powerful animal tranquilizer that is increasingly being found in the illicit drug supply.

Senate Bill 1773 amends the Illinois Controlled Substances Act to classify xylazine as a Schedule III controlled substance. The measure responds to a disturbing rise in overdose cases involving the drug, often referred to as the “zombie drug.” In addition to strengthening criminal penalties for the unlawful possession or distribution of xylazine, Senate Bill 1773 includes important protections for legitimate veterinary and wildlife use.

Data from the Illinois Department of Public Health shows that xylazine was detected in 45 overdose deaths in 2020 and in more than 200 deaths by 2022. While not approved for human use, xylazine is often used to enhance the effects of other drugs, making it especially dangerous and difficult to treat.

Senate Bill 1773 now moves to the House for consideration.
