Nitazene: The Undetected Opioid Driving Deaths
Nitazene is a strong, hard-to-detect opioid that's causing more deaths than we know.
It's often mixed with other drugs, and even small amounts can be deadly.
While fentanyl is still the main cause of opioid deaths, nitazene is becoming a bigger problem.
Nitazene, a synthetic opioid, is increasingly linked to opioid deaths.
It's five to nine times stronger than fentanyl and often goes undetected.
In 2023, 320 U.S. overdose deaths involved nitazenes, but the number is likely understated.
Fentanyl remains the top cause of opioid deaths, but nitazene's role is growing.
Small doses of nitazene can be deadly, and it's often found in other products.
