Fentanyl
FEN / FYL
Fentanyl is an extremely powerful Opioid pain medication that is approximately 50 times more potent than Morphine. It is a fully synthetic Opioid that was created in 1960 and approved for use in the US in 1968. It was intended primarily for post-surgical pain, palliative care, and other end-of-life pain. Fentanyl is a major contributor to overdose deaths in the on going opioid epidemic. Due to the low production costs, Fentanyl is being used illicitly to increase potency in otherwise less potent drugs often laced with or imitating other substances causing lethal doses. Make sure you are testing for Fentanyl.

How is it Used?
When prescribed by a physician, fentanyl is often administered via injection, transdermal patch, or in lozenges. However, the fentanyl and fentanyl analogs associated with recent overdoses are produced in clandestine laboratories. This non-pharmaceutical fentanyl is sold in the following forms: as a powder; spiked on blotter paper; mixed with or substituted for heroin; or as tablets that mimic other, less potent opioids.8 People can swallow, snort, or inject fentanyl, or they can put blotter paper in their mouths so that fentanyl is absorbed through the mucous membrane.
What are the Effects?
Like other opioids, fentanyl works the same way by binding to the opioid receptors in the brain producing euphoric pain relieving effects. This leads to high potential for dependency and abuse. Due it’s extreme potency, fentanyl can be fatal even in very small doses.
What does it Look Like?
Fentanyl is a potent synthetic opioid used medically to manage severe pain, particularly in cancer patients or post-surgery, and is available in various pharmaceutical forms. However, illicitly manufactured fentanyl is a major contributor to the opioid crisis, often mixed with other substances. Its forms include:
- Transdermal Patches: Adhesive patches delivering the drug slowly through the skin.
- Tablets/Lozenges: Prescription forms for controlled pain relief, often with unique markings.
- Injectable Solutions: Clear liquids used in clinical settings for rapid pain management.
- Nasal Sprays: Prescription sprays for quick absorption through nasal membranes.
- Illicit Powder: White or off-white powder, often mixed with other drugs like heroin or cocaine.
- Counterfeit Pills: Fake pills resembling prescription opioids but containing fentanyl, often in unpredictable doses.
Legitimate prescriptions are carefully packaged in labeled containers or individual blister packs, while illicit forms are sold in unmarked bags, pressed pills, or powders, often with dangerous variability in strength.
