The interagency efforts are aimed to both identify those who use anonymizing technologies to purchase illicit narcotics and direct them to available resources. Flashpoint analysts assess with a moderate degree of confidence that a portion of the remaining underground markets will likely ban the sale of fentanyl on their sites in an attempt to decrease law enforcement scrutiny. A handful of markets will, however, likely continue to sell fentanyl products due to high demand for the drug. My colleagues Joss Wright, Martin Dittus and I have been scraping the world’s largest darknet marketplaces over the last few months, as part of our darknet mapping project. The data we collected allow us to explore a wide range of trading activities, including the trade in the synthetic opioid Fentanyl, one of the drugs blamed for the rapid rise in overdose deaths and widespread opioid addiction in the US. The eDarkTrends NER algorithm was designed to identify and group opioid drug mentions into higher-level classes (e.g., heroin, pharmaceutical fentanyl, non-pharmaceutical fentanyl).

Fentanyl And Its Analogs
It is important to note that buying fentanyl from these markets is illegal and can be extremely dangerous. Underground markets have become important distribution channels for fentanyl and other drugs, helping connect consumers to a vast global supply chain of the deadly prescription drug. Out of 95,011 opioid-related listings, 3.3% (3,101/95,011) were for novel synthetic opioids. In comparison, heroin was identified in 55.2% (52,510/95,011) of all opioid-related listings, and there were 1,945 heroin-related listings per each crawl, on average.
Why Is Fentanyl So Dangerous?
Scientists are also working on opioid vaccines that would cause a person to develop antibodies to particular opioids and block their effects. This would offer a new approach to treating substance abuse, but the results of this research will likely not be known for years to come. Fentanyl is in a class of medications called narcotic (opiate) analgesics. It works by changing the way the brain and nervous system respond to pain.

Naloxone and naltrexone are opioid antagonists that reverse the effects of fentanyl. Fentanyl is a highly potent drug that can be fatal even in small doses. It is often mixed with other drugs, such as heroin or cocaine, to increase their potency. However, this also increases the risk of overdose, as users may not be aware of the presence of fentanyl in the drug they are taking. Additionally, because fentanyl is often made in illegal labs, there is no way to know the exact strength or purity of the drug, further increasing the risk of overdose. On average, there was about 1.1 kg of synthetic heroin listed for sale at each available data point.

The authorities used the time to gather information on high value targets and identified delivery addresses for sizable orders, passing along 10,000 international addresses of buyers to Europol. Law enforcement crackdowns targeting the dark web have increased and generated substantial wins in the last year. Starting with the Joint Criminal Opioid and Darknet Enforcement Team (JCODE) creation in 2018, coordinated international law enforcement initiatives have increased and ultimately led to some big wins in the past year. Darknet markets are online platforms that operate on the dark web, accessible only through specialized software like Tor.
A San Fernando Valley man and woman have been indicted for selling hundreds of thousands of dollars worth of fentanyl-laced pills and cocaine around the nation on dark web marketplaces, the U.S. Hydra Market, which started operating on the encrypted and anonymous dark web in 2015, made up 80% of darknet sales and brought in about $5.2 billion in cryptocurrency, according to the U.S. Hydra’s servers were seized in Germany by police there Tuesday morning in coordination with U.S. law enforcement. The modern epidemic of fentanyl adulteration is far broader in its geographic distribution, production and number of deaths. Overdose deaths roughly quadrupled, going from 8,050 in 1999 to 33,091 in 2015. Fentanyl is a popular product on darknet markets due to its high potency and low cost.
