A map that shows states in yellow if it has decriminalized the possession of drug checking equipment, orange if it has made an exception for fentanyl, and red if drug checking equipment is criminalized. Six states are in red: Idaho, North Dakota, Texas, Illinois, Indiana and Iowa. Illinois is weird because equipment to test if drugs have been altered is legal as of Jan. 1, 2024. Some states, like California and Kansas, have broader exceptions to their DCE laws for synthetic opioids, ketamine and gamma hydroxybutyric acid (or GHB, sometimes simply referred to as G).
