There are two types of fentanyl: medical and illicit. Both are synthetic opioids.
Fentanyl is not well-absorbed by the skin, so people can’t overdose by accidentally touching illicit fentanyl, which typically comes in pill or powder form.
Medical fentanyl takes different forms, including shots, patches on the skin or lozenges. The medical patches adhere to skin, and the skin slowly absorbs the opioid.
Naloxone, sold under the brand name Narcan, is a medicine that reverses overdoses from opioids like fentanyl.
Fentanyl is a potent and lethal synthetic opioid, causing the majority of opioid overdoses in the U.S., according to the Centers for Disease Control and Prevention.
Despite being the subject of many news stories and political talking points, the drug is still the source of a lot of confusion. PolitiFact recently dispelled common myths about fentanyl, including that unintentional exposure to the drug in its pill or powder form can cause an overdose.
We asked you, our readers, to send us your questions about fentanyl. Here are answers to the most commonly asked questions.

There are two types of fentanyl: pharmaceutical (what our reader called "medical fentanyl"), and illicit (which the reader called "street fentanyl"). Medical fentanyl also is a synthetic opioid, according to the CDC.
"Fentanyl is an old, well-understood drug that is used safely" every day in medicine, said Dr. Ryan Marino, a Case Western Reserve University toxicologist and emergency room physician who studies addiction. "It is one of the most valuable and most" commonly used "medical therapeutics."
Illicit fentanyl, on the other hand, is made in clandestine labs and is the version of the drug most closely associated with overdose deaths. Illicit fentanyl, according to the Drug Enforcement Administration, can be sold as a powder, pill or nasal spray.

Despite viral stories of police officers or emergency responders supposedly overdosing or getting sick through unintentional contact with fentanyl, experts say it’s not scientifically possible. Fentanyl isn’t well absorbed by the skin, especially in its illicit forms.
However, medical fentanyl is sometimes administered through skin patches. But experts say this isn’t evidence that you can get sick by touching fentanyl in powdered or pill form.
For example, even though there are nicotine patches, your skin can’t absorb nicotine by touching tobacco, "and the same principle applies to fentanyl," according to a report from Brandon Del Pozo, a Brown University public health expert.
However, the Food and Drug Administration warns about the possibility of children accidentally overdosing after exposure to fentanyl patches. According to the Mayo Clinic, if you touch the sticky side of a fentanyl patch you should contact a medical professional and rinse the area with water.

Naloxone, a medicine commonly sold under the brand name Narcan, reverses opioid overdoses, according to the National Institute on Drug Abuse. Naloxone is administered via nasal spray or injection. Sometimes multiple doses are needed, depending on the strength of the opioid.
The National Institute on Drug Abuse says friends, family members and bystanders can give a person naloxone in case of an opioid overdose. However, the person should still seek emergency medical assistance. Naloxone reverses an opioid overdose for 30 to 90 minutes, so it is possible overdose symptoms can return once the treatment wears off.
The DEA says that as little as 2 milligrams of fentanyl can be deadly for an adult. However, a dose’s lethality can vary based on height, weight and tolerance from past exposure.
Fentanyl’s potency is what makes it so lethal.
Most illicit fentanyl in the U.S. comes from Mexico, mainly smuggled by U.S. citizens. Illicit fentanyl seizures are higher at official ports of entry than in between ports of entry, U.S. Customs and Border Protection data shows.
However, illicit fentanyl also arrives in the U.S. by mail, passenger boats, cargo ships, commercial planes and drones, according to a report from Rand Corp., a global policy think tank. Most of the illicit fentanyl that comes from Mexico is made in labs using chemicals from China, the Rand Corp. report said.
Politicians, news reports and government agencies often cite federal fentanyl seizure statistics to claim that enough is seized to kill a high number of people. For example, in January, the DEA said that in 2022 it seized enough illicit fentanyl nationally to kill every American.
However, there are some caveats. As we mentioned before, certain characteristics, such as a person’s weight, can affect lethality. Also, it’s unclear how pure all the seized fentanyl is, which can also affect lethality, Timothy J. Pifer, the director of the New Hampshire State Police Forensic Laboratory and a specialist on fentanyl’s lethality, told PolitiFact in 2019.
Just because enough fentanyl has been seized to kill every American does not mean every American has the same chance of dying of a fentanyl overdose, said Dr. Andrew Stolbach, a toxicologist and emergency doctor at the Johns Hopkins Hospital.
"That would assume that all that drug was somehow going to get into everybody," Stolbach said.
Stolbach said there’s likely enough water to drown everybody in the world. But that doesn’t mean everyone is going to drown.
