介绍： Tiffany and James say naloxone has not changed the way they think about heroin, but both have friends who treat naloxone like a safety net. Tiffany says she has one friend who assumes that "if he overdoses, someone will come give him Narcan and bring him back."

But would her friend stop using heroin if he didn't have Narcan?

"No," she says. "There ain't no way."

The possibility that naloxone might lead to greater risk taking among drug users prompted two economists to study the issue. Their controversial and hotly-debated findings suggest naloxone not only increases risky drug use but may actually cause more deaths than it saves. Public health researchers say these findings are based on flawed data and analyses.

This week on Hidden Brain, we talk with users, families, and researchers about risky drug use. We'll try to understand the complex risk/benefit calculations involved in opioid use, and why there's still so much we're struggling to understand about addiction.

Editor's Note:

In this story, Jasmine Pierce, an overdose response coordinator for the Anne Arundel County Department of Health, says that county officials "provide gloves inside of the kits... to protect you from any type of contamination because, with both of those drugs, they can actually seep through your skin with skin-to-skin contact, and you can overdose yourself."

Here's what the CDC has to say about the risks of opioid exposure to first responders:

"Fentanyl and its analogues pose a potential hazard to a variety of responders who could come into contact with these drugs in the course of their work. Possible exposure routes to fentanyl and its analogues can vary based on the source and form of the drug. Responders are most likely to encounter illicitly manufactured fentanyl and its analogues in powder, tablet, and liquid form. Potential exposure routes of greatest concern include inhalation, mucous membrane contact, ingestion, and percutaneous exposure (e.g., needlestick). Any of these exposure routes can potentially result in a variety of symptoms that can include the rapid onset of life-threatening respiratory depression. Skin contact is also a potential exposure route, but is not likely to lead to overdose unless large volumes of highly concentrated powder are encountered over an extended period of time. Brief skin contact with fentanyl or its analogues is not expected to lead to toxic effects if any visible contamination is promptly removed. There are no established federal or consensus occupational exposure limits for fentanyl or its analogues."
