Fentanyl exerts its pain-relieving effects by acting on opioid receptors that occur naturally in the body. Endorphins, the substances in the body that normally bind to opioid receptors and naturally relieve pain, are also connected with “pleasure centers” in the brain. Repeated activation of these centers by narcotic drugs is suspected of playing a role in drug addiction.

Healthcare providers, law enforcement, and the public should stay aware of these changes. “This is just the first of many studies to come that can potentially stop the large trade of opioids,” Champagne-Langabeer said. “I think we proved that by using coding language, we are able to match their level of sophistication and hopefully one day control the source.”
Efforts To Prevent Fentanyl Overdoses
Physical dependence results in withdrawal symptoms when individuals suddenly stop taking the drug. Doctors will only prescribe the fentanyl patch to people who are already tolerant of opioid therapy that is similar in strength. Fentanyl can continue to be effective after removing the patch, as the skin has already absorbed the drug.
Fentanyl Overdose
It’s used to treat severe pain, for example during or after an operation or a serious injury, or pain from cancer. If you unknowingly take fentanyl in another drug, you may overdose since fentanyl is so potent. Withdrawal symptoms typically start within 12 hours after your last dose of the drug. The first 3 days are the hardest, with the most severe symptoms. But these tips can reduce some of that risk and lower your chances of overdose, infection, or other problem.

Your doctor or pharmacist will show you and your family members how to use the medication. Ask your pharmacist for the instructions or visit the manufacturer’s website to get the instructions. If symptoms of an overdose occur, a friend or family member should give the first dose of naloxone, call 911 immediately, and stay with you and watch you closely until emergency medical help arrives.

Our Research and Investigations Team also focuses on identifying new ways vendors use to disguise the trade of such illicit goods. Our research also shows that alongside darknet markets, some darknet vendors have set up smaller online stores selling fentanyl. If a patient is taking this drug on a prescription basis, they need to communicate immediately with their physician if they experience any adverse effects.
It is prescribed to treat severe pain but is also misused and a major contributor to the opioid crisis. “In health care, we dose fentanyl in micrograms,” explains Amanda N. Donald, MD, an addiction medicine physician at Northwestern Medicine. Fentanyl is a synthetic opioid that can be prescribed by doctors for pain management (National Institute on Drug Abuse NIDA, 2021). It is also increasingly found mixed into street drugs (Drug Enforcement Administration DEA, 2024).
FIND TREATMENT:
As a synthetic opioid, fentanyl attaches to the body’s opioid receptors, which are found in areas of the brain that control pain and emotions. When fentanyl binds to these receptors, it can create intense feelings of euphoria and relaxation, but it also carries a high risk for addiction and overdose. Fentanyl is a synthetic opioid that is 50 to 100 times more potent than morphine.
According to the report, the street value of the 500 online transactions discovered by the Subcommittee in its investigation conservatively translates to around $766 million-worth of fentanyl. From April 2024 to March 2025, the CDC reported 43,000 synthetic opioid deaths, most of which are from fentanyl, down from nearly 70,000 in the previous similar period. Medications are the standard treatment for fentanyl addiction.32,33 Several medications have been approved by the U.S. Food and Drug Administration (FDA) for the treatment of opioid use disorder. Another medication, lofexidine, has been approved for treatment of withdrawal symptoms.34 See “Medications for Opioid Use Disorder” for more information.

- Common pharmaceutical industry fentanyl analogs used during surgery include sufentanil (Sufenta), alfentanil (Alfenta) and remifentanil (Ultiva).
- National Harm Reduction Coalition creates spaces for dialogue and action that help heal the harms caused by racialized drug policies.
- Illegal drug sales on the streets and in online drug markets are thriving at the expense of our loved ones, supplying potent substances leading to higher rates of overdose than ever before.
- If someone who has overdosed does not have a pulse, start CPR.
- Misuse of fentanyl includes taking it orally, smoking it, snorting it, or injecting it.
The second implication is how these risks are assessed and uncovered. Regardless of how vendors try to conceal their fentanyl listings on the dark web, their activities can nevertheless be exposed through blockchain analytics. One dark web marketplace – the since-retired “ASAP Market” – was particularly selective about enforcing its apparent “no fentanyl” policy. The image below shows a listing disguised as “synthetic China White”. Dark web market rules prohibiting the sale of fentanyl on their platforms.

Portman and a bipartisan group of senators have actually introduced legislation to require the Postal Service to collect this electronic data. It is also an idea that President Trump has at times endorsed. There are hurdles, including international treaties and the readiness or willingness of other countries to implement the same standards. The investigators didn’t actually execute a purchase, because even a small amount of fentanyl can be lethal. But they learned how simple it was to buy these powerful opioids online and how brash the sellers were. A lot of experts would say that tackling demand and making treatment more accessible should be the top priority.

This combination can result in an individual consuming a much stronger substance than they are used to, resulting in overdose and possibly death. The DEA has found an average of 2.4 milligrams of fentanyl in the pills they test (DEA, 2024). People who use drugs might not be aware they are taking fentanyl, yet the reality is that fentanyl-laced drugs are prevalent. In 2022, the DEA seized more than 50 million street pills laced with fentanyl — more than twice as many in 2021. Of the fentanyl-laced street pills analyzed by the DEA in 2022, 60% contained a potentially lethal dose of fentanyl. Fentanyl is increasingly found in street drugs that have been stamped with illegally purchased pill presses to look like other common pharmaceutical-grade drugs, such as oxycodone.

What Is Fentanyl’s Role In The Overdose And Addiction Crisis?
Over that time period, he received 15 packages through the Postal Service on dates that closely corresponded to payments he made to an online seller. He died in early 2017 from “acute fentanyl intoxication.” He had received a package from an online seller just 30 days before his death. To get extremely potent opioids, users turn to the dark web—and sometimes, Google.

Due to its high potency and low cost per dose, street dealers have found it to be a useful filler or substitute when selling other, more expensive street drugs. A fentanyl transdermal patch will cost around $40 on the street. These are designed to provide an extended-release dose of fentanyl over the course of 72 hours. It’s crucial to remember that there is no way to verify the actual content or purity of fentanyl bought illicitly. Even a small amount of fentanyl can be deadly, and using it, particularly when obtained illegally, carries extreme risks. He decided to seek out something that would be both safer and cheaper.
