Prosecutors on Tuesday said 325 people — including more than 280 alleged users and 40 dealers — were snared during the eight-week operation that targeted Paterson-based drug operations.

Authorities also seized approximately 1,200 grams of raw heroin — enough to sell about 60,000 bags on the street — and another 12,000 bags from users. The heroin has an estimated street value of $350,000.

Authorities also seized 30 guns and over $25,000 during the operation, which involved undercover agents and surveillance.

The federal Drug Enforcement Agency says Paterson supplies more pure heroin than anywhere else in the country.
