Contaminated pills lead to deaths, overdoses
ST. JOHNSBURY, VT - FEBRUARY 06:   Drugs are prepared to shoot intravenously by a user addicted to heroin on February 6, 2014 in St. Johnsbury Vermont. Vermont Governor Peter Shumlin recently devoted his entire State of the State speech to the scourge of heroin. Heroin and other opiates have begun to devastate many communities in the Northeast and Midwest leading to a surge in fatal overdoses in a number of states. As prescription painkillers, such as the synthetic opiate OxyContin, become increasingly expensive and regulated, more and more Americans are turning to heroin to fight pain or to get high. Heroin, which has experienced a surge in production in places such as Afghanistan and parts of Central America, has a relatively inexpensive street price and provides a more powerful affect on the user. New York City police are currently investigating the death of the actor Philip Seymour Hoffman who was found dead last Sunday with a needle in his arm.  (Photo by Spencer Platt/Getty Images)

Story highlights

"I am going to create borders. No drugs are coming in. We're going to build a wall," Trump said

The appeal, made in a video posted to Facebook, comes three days before New Hampshire hosts the nation's first 2016 primary.

(CNN) —  

Donald Trump on Saturday again vowed to build a wall along the Mexico-U.S. border – this time arguing that it would help stem New Hampshire’s “drug epidemic.”

The appeal, made in a video posted to Facebook, comes three days before New Hampshire hosts the nation’s first 2016 primary.

“New Hampshire has a tremendous drug epidemic,” Trump says. “I am going to create borders. No drugs are coming in. We’re going to build a wall. You know what I’m talking about. You have confidence in me. Believe me, I will solve the problem.”

“They will stop coming to New Hampshire. They will stop coming to our country,” he added.

Trump has repeatedly said he will build a wall along the southern border of the United States to prevent undocumented immigrants from entering the country.

The businessman also said he will work to help people struggling with addiction.

“And the people that are in trouble, the people that are addicted, we’re going to work with them and try and make them better. And we will make them better,” Trump said.

Trump does not address prescription drug addiction in the video, which has been a focus of New Hampshire legislators.

According to an October 2015 survey from the University of New Hampshire and WMUR, a quarter of Granite Staters think drug abuse is the most important problem facing the state, the first time in eight years that a plurality think an issue is more important than jobs and the economy. The epidemic reaches across all demographics and nearly half of those surveyed say they know someone who has abused heroin.

Several Republican candidates, including former Florida Gov. Jeb Bush, New Jersey Gov. Chris Christie and Texas Sen. Ted Cruz, have spoken about how they would address drug addiction as president.
