MANCHESTER, N.H. – Students in Manchester schools are learning the ugly truth about drug addiction, courtesy of local director of emergency services Chris Hickey.

Hickey, who works for the Manchester Fire Department, has been making rounds at area high schools with a PowerPoint presentation that is “supposed to make you sick” with images of drug overdose deaths, and other graphic pictures of drug culture, the New Hampshire Union Leader reports.

“Heroin will kill you,” said Hickey, a paramedic who rushes dozens of high school students and other drug addicts to the emergency room each month. “I can’t save everybody. There’s no reset button.”

Hickey launched his presentation at Manchester High School West last week with the typical spreadsheets and talking points about a drug epidemic in New Hampshire that’s growing by the day.

He used bar graphs and statistics to illustrate his point, but it’s the gruesome images that put a face to the numbers that captured students’ attention, and even make a few sick enough they were forced to leave the presentation.

From the Union Leader:

Eventually, Hickey transitions into the images he sees when doing his job.

* Arms with inflamed pustules rising like hills over valleys of collapsed, bruised veins.

* Mug shots of comely women and healthy men who within a year stare at the camera with gaunt faces and weary eyes.

* Newly born, drug-addicted babies, tiny in size with misplaced brains and eyes.

* Dead bodies: one on a bathroom floor, another on a park bench, another covered in his own vomit.

* The bodies of the famous: Chris Farley, John Belushi, River Phoenix and Amy Winehouse — whose careers explode then collapse like a supernova.

“In the last 10 years, the number of people admitted to state-funded treatment programs rose by 90% for heroin use and by 500% for prescription opiate abuse, according to a 2014 study from the New Hampshire Department of Health and Human Services,” according to CNN.

“The state is also ranked first in the country when it comes to levels of drug dependence among 18- to 25-year-olds, according to the National Survey on Drug Use and Health from 2012-2013.”

Students in Manchester said Hickey’s presentation brought those statistics to life.

“It’s an eye opener,” freshman Jaymeson Maheux told the Union Leader. “I feel like some (drug dealers) target kids, customers who would live longer.”

Maheux’s friend, William Tyler, said he knows at least two people personally who have died of drug overdoses.

Hickey said he launched the presentation in response to an obvious increase in overdose emergency calls, and Mayor Ted Gatsas is incorporating it into an overarching 60-day action plan to combat the problem.

He’s shared his presentation with all of the city’s high schools, and could soon take his message to other districts. Hinkey is also developing a video with interviews with addicts and parents of those who died of an overdose.

“But for the time being, Hickey’s presentation is the city’s primary effort to vaccinate our youth from the heroin epidemic,” the Union Leader reports.

Ann Marie Banfield, a parent activist, wrote on Facebook, “No parents were notified this would be shown to their kids. No information on whether the program is effective.”
