Fentanyl Information

Fentanyl can show up in social situations and substances where people don’t expect it. This page shares information to help you understand what fentanyl is, why it’s risky and what you can do to reduce harm and look out for yourself and others.

̽»¨ÊÓÆµ Fentanyl

Fentanyl is a synthetic opioid that is 50–100 times more potent than heroin or morphine. Because it’s cheap to produce and very strong in small amounts, drug traffickers often mix fentanyl into other drugs.Ìý

The problem? People often don’t know it’s there.Ìý

Why Fentanyl is High Risk

Fentanyl is often hidden in other substances or sold as something else entirely, increasing the risk of accidental overdose.Ìý

It has been found in:Ìý

  • Powders (like cocaine)Ìý
  • CapsulesÌý
  • Pressed pills made to look like prescription medications (such as Xanax or Oxy/M30s)Ìý
  • Other substancesÌý

As little as two milligrams of fentanyl can be lethal. Many counterfeit pills contain more than twice that amount, even though the dose is nearly invisible to the eye.Ìý

Important: Any pill or drug not purchased directly from a pharmacy could contain fentanyl, even if it looks legitimate.Ìý

Fentanyl is also more common than many people realize.Ìý

  • Colorado has seen a significant increase in fentanyl presence and overdoses.Ìý
  • Nationally, fentanyl deaths are decreasing, and fentanyl remains the leading cause of death in the United States for ages 18-44.
  • Nearly half of counterfeit pills tested by the DEA contain a potentially lethal dose.Ìý

Counterfeit pills can closely resemble real prescriptions, making it very difficult to tell the difference.Ìý

Ways to Reduce Risk and Stay Safer

While fentanyl can be deadly, there are steps you can take to reduce harm and protect yourself and your friends.Ìý

Please note: Because fentanyl is unpredictable, there is no way to fully eliminate overdose risk. These strategies can reduce risk but not remove it entirely.Ìý

Know what you’re using

Assume that any drug not purchased directly from a pharmacy may contain fentanyl, including:Ìý

  • Illicit drugs (cocaine, heroin, meth, etc.)Ìý
  • Pills sold as prescription medications (Xanax, Oxycodone, etc.)Ìý

Additionally, using substances alone increases overdose risk. If possible:Ìý

  • Be with someone who is soberÌý
  • Have someone check in on youÌý
  • Keep naloxone nearby and make sure others know how to use itÌý
Start small and go slow

Fentanyl is often unevenly mixed into drugs. One dose may be survivable, while the next may not be.Ìý

  • Start with a very small amountÌý
  • Wait before using moreÌý
  • Avoid re‑dosing quicklyÌý

If you’ve taken a break from using substances, your tolerance may be lower than before.Ìý

Lower tolerance increases overdose risk—especially with fentanyl. If you choose to use again, start with much less than you previously used.Ìý

Carry naloxone and use fentanyl test strips

Naloxone is an FDA‑approved medication that can temporarily reverse opioid overdoses.Ìý

  • Commonly administered as a nasal sprayÌý
  • May wear off quicklyÌý
  • Multiple doses may be needed for fentanylÌý

Free naloxone is available to all ̽»¨ÊÓÆµ students, staff and faculty at Health Promotion on the third floor of Wardenburg Health Center.Ìý

Additionally, fentanyl test strips can help detect fentanyl, but they are not foolproof.Ìý

  • A negative result does not guarantee safety.Ìý
  • Fentanyl may be unevenly distributed—it may be in some parts of the drug and not others. Test all the drug that will be consumed.Ìý
  • Unknown drugs other than fentanyl may still be present, including other opioids.Ìý
Recognize an overdose and act fast

Common signs of opioid overdose include:Ìý

  • Pinpoint (very small) pupilsÌý
  • Shallow or stopped breathingÌý
  • Blue or gray lips or fingernailsÌý
  • No response to sound or touchÌý
  • Gurgling or heavy snoring soundsÌý

If an overdose is suspected:Ìý

  • Try to wake the person and check for a response.Ìý
  • Use a sternum rub (firm pressure with knuckles to the center of the chest).Ìý

If there is no response:ÌýÌý

  • Call 911Ìý
  • Administer naloxoneÌý
  • Start CPR if trainedÌý
  • Stay with the person until help arrivesÌý

Naloxone will not harm someone who is not overdosing. When in doubt, use it.Ìý

Good news: CU’s Amnesty Policy and Colorado’s can protect you from disciplinary action or prosecution if you call for help and stay with the person.Ìý
