WOODBURY - An epidemic and a crisis are the two words used to describe the influx of heroin in communities on Long Island.

News 12's Eileen Lehpamer sits down with federal and local law enforcement in part two of our series "Heroin: Addicted on long Island."

James Hunt, special agent in charge of the New York field office of the Federal Drug Enforcement Administration, spoke to News 12 about this past year's efforts and how heroin is getting to the island.

Hunt says the majority of the heroin is from South America that the Mexican drug cartels are smuggling into the United States. "They're creating a market, they want heroin to be cheap and easy to get, and they're hoping more people get addicted, basically. That's their business plan," says Hunt.

Officials say cars and tractor-trailers are driving across the border and are rigged with secret hidden compartments.

Nassau Chief of Department Steven Skrynecki says one of the most serious trends is dealers intentionally mixing the heroin with a prescription anesthetic to make it even more powerful. Fentanyl is 50 to 100 times stronger than morphine.

The Nassau Police Department says to help combat the problem it has created a video as part of its continued anti-drug outreach in schools, and it is looking to work more closely with the Health Department to get addicts the help they so desperately need.
