There is a growing concern about accidental or secondary exposure to illicitly manufactured fentanyl (IMF) and its potential to cause an overdose. Examples of accidental fentanyl exposure may include:
- Exposure to secondhand smoke from someone smoking fentanyl in a public place
- Exposure to fentanyl residue in a public place or on a piece of mail
Accidental exposure to secondhand fentanyl smoke, fentanyl powder, or fentanyl residue is highly unlikely to cause an overdose. Accidental fentanyl ingestion, which occurs when someone consumes a drug unknowingly containing fentanyl, is much more common and significantly more dangerous.
To date there is no evidence of community members or first responders experiencing an overdose from accidental or secondhand fentanyl exposure. First responders have different guidelines for preventing and responding to fentanyl exposure. For more information, please refer to the “Resources" section at the bottom of this page.
If you witness someone who might be experiencing an overdose, it is safe to help them. It is safe to touch them, administer naloxone, and provide rescue breathing or chest compressions.
Touching Fentanyl
You cannot overdose by touching fentanyl powder or counterfeit pills containing fentanyl. Fentanyl is not easily absorbed through the skin and there are no confirmed cases of this type of overdose scenario.
The only known way fentanyl can be absorbed through your skin is if you use a specially designed fentanyl patch that has been prescribed to you by a healthcare provider. But even then, it takes hours of contact for the fentanyl patch to take effect.
In the case that you accidentally touch fentanyl, do not panic, as accidental skin contact is highly unlikely to cause harm. Avoid touching your face and wash the affected area with soap and water immediately. Do not use alcohol-based hand sanitizers. Remove and wash any contaminated clothing separately. If you feel unwell or have concerns, seek medical attention right away.
If there are large amounts of fentanyl-containing pills or powder present, call 911. To clean up a small number of pills or powder, wear nitrile gloves, an N95 mask, and eye protection. Clean hard surfaces with a damp cloth. Vacuum carpet and fabric surfaces with a HEPA-filtered vacuum.
Breathing in Secondhand Fentanyl Smoke
There have been no clinically confirmed overdoses from people who accidentally inhaled secondhand fentanyl smoke. "Secondhand fentanyl smoke" refers to smoke produced by burning fentanyl pills or powder, or from the exhalation of someone who has smoked fentanyl. Even if you can smell smoke, the risk from being in or near exhaled fentanyl smoke is extremely low.
To clean an area where fentanyl has been smoked, open windows or run a fan to air out the space. Clean surfaces with a damp cloth. Wear nitrile gloves and an N95 mask for protection.
Breathing in Airborne Fentanyl
Fentanyl powder does not easily become airborne, and the powder from the drug does not linger in the air. To be at risk for overdose from fentanyl powder, there would have to be large amounts of powder suspended in the air for a prolonged time. Such an event is highly unlikely.
If there is a large amount of fentanyl powder present, call 911. To clean up a small amount of fentanyl powder, wear nitrile gloves, an N95 mask, and eye protection. Clean hard surfaces with a damp cloth. Vacuum carpet and fabric surfaces with a HEPA-filtered vacuum.
