Fentanyl test strips can help prevent overdose because they tell you if your drugs contain a deadly opioid like fentanyl. We’ve seen this added to heroin, meth, cocaine, and pills. You should use these test strips on all drugs, not just heroin. But, understand that there’s still a risk, even with these test strips as it may not pick up all relatives of fentanyl. If you would like to test your drugs, inquire about picking up these test strips at your local health department.
