Cases in which fentanyls are sold under the guise of heroin are common worldwide 6. In some, ocfentanil was labeled and sold in the darknet as heroin or “synthetic heroin” 6, 44, 59, 76. It was firstly reported in EWS within a seizure of “synthetic heroin” in the Netherlands 44, 50, 70. Furthermore, four samples, purchased in or sent from France and Spain, were analyzed by Energy Control in Barcelona, two of which were found to contain ocfentanil, caffeine, and acetaminophen. An alert was notified to public and the authorities and was quickly spread throughout the web. The information reproduced in English, French, German, Swedish and Polish drug forums and online discussions pointed out two vendors that were eventually banned from deep web marketplaces 59, 71–74.
- Three groups received ocfentanil at different doses (0.1, 0.5, 0.75 μg/kg) and the fourth received morphine 0.07 mg/kg.
- Special emphasis is given to carfentanil-related non-fatal and lethal overdose cases.
- According to the DEA, most of the carfentanil showing up on the streets today originated in clandestine drug labs in China.
- The carfentanil-involved fatal overdose outbreak in the Sarasota area epicenter began in June 2016, lasted for at least 12 months, and abruptly ended in August 2017.
- In addition to basic supportive care and airway management, administration of opioid antagonists, such as naloxone, is critical.
Side Effects of Carfentanil Use
“Instead of having four or five overdoses in a day, you’re having these 20, 30, 40, maybe even 50 overdoses in a day,” says Tom Synan, who directs the Hamilton County Heroin Coalition Task Force in Southwest Ohio. In Australia, carfentanil has been included in the Poisons Standard in June 2017, by the Australian Department of Health. It has been clarified as a schedule 8 poison, and legal restrictions apply to its manufacture, supply, distribution, possession, and any type of abuse, physiological misuse, or physical dependence 154.

It is a mu-opioid receptor agonist with an estimated analgesic potency approximately 10,000 times that of morphine and times that of fentanyl, based on animal studies. Since 2016, an increasing number of reports describe detection of carfentanil in the illicit drug supply. Its high potency and presumed high lipophilicity, large volume of distribution, and carfentanil: uses, interactions, mechanism of action drugbank online potential active metabolites have raised concerns about the management of people exposed to carfentanil as well as the safety of first responders.
Carfentanil Withdrawal and Detox
Someone who overdosed on carfentanil may feel cold to the touch, shiver, and have a bluish tint. The reasons for losing consciousness can include sedation/sleepiness, slow breathing, slowed heart rate, and a combination of all 3. Outpatient carfentanil rehab is less intensive than inpatient rehab, often involving shorter sessions. In outpatient rehab, you live at home but attend sessions at the facility, although teletherapy options may also be available.
Side Effects of Carfentanil Drug Abuse
It has been reported through seizures, intoxication cases, and illicit drug trafficking in Europe, Asia, the USA, and Australia 14, 40, 41, 43, 45, 46, 110–113. Carfentanil is a fentanyl analog, or a synthetic opioid chemically similar to fentanyl. It’s 100 times more potent than fentanyl and 10,000 times more potent than morphine. Because of that, carfentanil is considered the strongest and most dangerous fentanyl derivative.
- Overdose prevention efforts that address widespread presence of IMFs, including carfentanil, and can rapidly adapt to other potent opioids in the drug supply, might result in lasting reductions in overdose deaths across the United States.
- Their diverse expertise ensures our resources and product are innovative, evidence-based, and effective.
- You can save someone who’s overdosed on carfentanil by immediately using Naloxone.
- It also has a rapid onset compared to other substances in the opioid family, which can make it more difficult for its effects to be reversed by naloxone (Narcan) in time.
§§ Fentanyl was classified as likely illegally manufactured using toxicology, scene, and witness evidence. IMFs entered western U.S. drug markets later than other regions, likely because of challenges mixing fentanyl into the black tar heroin that was more common in the West (1). Recent increases in counterfeit pills containing IMFs, particularly in the West, have helped IMFs infiltrate the market, increasing overdose risk (8).
He was previously hospitalized after using cocaine combined with sleeping pills. The victim was also receiving antidepressant medication until 3 months before the incident. Drug paraphernalia and a small reclosable zipper bag with 2.07 g of a brown powder were found next to the body. Police investigation revealed that the drug had been purchased online with bitcoins and snorted with a straw. Liquid-liquid extraction (LLE) and ultra performance liquid chromatography (UPLC) were used to identify and quantify the drug in the postmortem fluids of the deceased. Hair analysis revealed that the victim was also a cocaine and heroin user.
Drug dealers in the United States can purchase carfentanil online and have it shipped through the mail. In 2002, Russian military forces used an aerosolized version of carfentanil to end a hostage situation with Chechen separatists in a Moscow theater. The drug was pumped into the theater through the air vents and ended up killing more than 120 hostages.

What to Know About Carfentanil Abuse
They replaced the nitrogen in the piperidine ring of carfentanil with a carbon in order to assess how the electrostatic interaction of nitrogen with Asp protein of the opioid receptor affects binding and activation of opioid receptors. The trans isomer of c-carfentanil was found to result in a 4000-fold decrease in mOR binding affinity than carfentanil, but was still significant. Its δ opioid receptor (dOR) binding affinity was found to be similar to that of mOR, but no receptor selectivity was observed between mOR and dOR receptors. This isomer did not show any significant binding affinity with the κ opioid receptor (kOR). The cis isomer did not show any significant binding affinity with any one of the three receptors 35.
Intoxications and fatal cases
Labeled carfentanil have been also synthesized in order to be used mainly in pharmacology studies on the µ opioid receptor (mOR) binding 104, 105. A simple synthesis of 11C carfentanil was described by Jewett in 2001. Initially the tetrabutylammonium salt of 4-N-(1-oxopropyl)-N-phenylamino-1-(2-phenylethyl)-4-piperidinecarboxylic acid reacted with 11C methyl triflate in dimethyl sulfoxide (DMSO).
