Nitazenes are strong opioids sometimes found in heroin or counterfeit pills.

Overdose response
Naloxone and breathing support
Dose and test strips
A scale can’t tell you how much is in a pill or powder. Fentanyl strips miss nitazenes. A separate nitazene strip can still miss some types or small amounts.
Ask a drug-checking service what it can detect. Ask separately about other newer opioids such as cychlorphine.
Respond to an overdose
Keep naloxone handy and avoid using alone. If someone can’t wake up or breathe normally, call 911 and give naloxone. Follow the dispatcher’s instructions. Give another dose as directed if breathing hasn’t returned.
