Nitazenes Global Alert

In 2023, nitazene tablets destined for Florida, Connecticut, and Brazil containing an average of 29 mg of metonitazene across multiple shipments were seized in the U.S. from international express mail. This amount is equivalent to 290 mg of fentanyl in a single tablet (or 145 times the DEA’s estimated fatal dose of fentanyl), which would be highly lethal.

Injectable Liquid Fentanyl

Fentanyl misuse or abuse typically involves injection or smoking of illicitly manufactured fentanyl (IMF). Illicit fentanyl is most commonly sold on the street as counterfeit tablets or as powders in folded glassine papers.
