Boston authorities found 33 pounds of fentanyl -- enough to wipe out all of Massachusetts.

This is one of the most successful wiretap investigations in the history of the state.

Prosecutors said the synthetic opioid was sold on the streets by a gang linked to Mexico’s Sinaloa Cartel, which was once led by Joaquin “El Chapo” Guzman.

The Boston Herald reported 33-pounds of fentanyl would be enough to kill more than 7 million people in its raw form - more than the population of Massachusetts which is 6.8 million.

'Operation High Hopes,' led to the confiscation of 77 pounds of the drugs, $300,000 in drug money and 37 suspects, including alleged kingpin Robert Contreras.
