Wanna hear something crazy? Fentanyl test strips are FDA-approved to quickly test for the presence of the dangerous drug in the urine in overdose cases. They can also be used to check for fentanyl in street drugs and counterfeit pills. But in more than 40 states, this is illegal (!). Why? Because they are considered to be drug paraphernalia. Seriously. Good luck finding any policy or law dumber than this.
