In this way, we generated a rich underground marketplace opioid vocabulary of 311 opioid keywords with 13 categories. Third, we conducted a comprehensive, large-scale, longitudinal study to measure and characterize opioid trading in anonymous online marketplaces and forums. To the best of our knowledge, a comprehensive overview of the opioid supply chain in the anonymous online marketplaces and forums, as well as a measurement study of trading activities, is still an open research challenge.
Dark Net Markets Have Proliferated Since Silk Road

One study, published by the International Journal of Drug Policy, scrutinized lab results of more than 200 samples of drugs that were purchased on so-called cryptomarkets and collected by a Spanish NGO from 2014 to 2015. The study found more than 90 per cent of the samples contained the drugs they were sold as, and that most samples were of high purity. Policing involves targeting specific activities of the private web deemed illegal or subject to internet censorship.

Cyber investigations sometimes begin as traditional in nature then progress into the cyber environment. HSI was one of the primary agencies on the Silk Road investigation that revealed large-scale illegal drug and contraband smuggling through the U.S. The investigation eventually led to activity taking place on Darknet marketplaces. “This case, along with Black Market Reloaded, represented a new and evolving area, cyber investigation, for law enforcement that continues to this day,” said DAD Lechleitner. And the fragmentation of illicit markets, particularly in drug sales, signals a shift toward decentralization — with criminal enterprises moving away from traditional darknet marketplaces toward more agile and resilient platforms.

Cryptomarkets are part of an evolving trend where communities of PWUD adapt and develop technological systems to their ends. The cryptomarket distribution system is emblematic of the move to drug distribution by delivery, whether through the postal system or tailored distribution services. They may now be being superseded in technical prowess by well-crafted, custom-built systems that use messaging apps 55, 56 and rather than representing the future are an established and stable if evolving niche.

Periodically one disappears following a police raid, sparking panic and worry among the community of users. But the dark net markets learn from each mistake and are becoming more secure and more decentralised, making them incrementally more difficult to combat. Tor’s clever traffic encryption system makes it very difficult for the police to know where these sites — and the people who use them — are located. It’s a natural place for an uncensored drugs marketplace, as it is for whistleblower websites and political dissidents, which also use the same techniques to keep their visitors hidden. In January 2015, the case went to trial in the Southern District of New York and exposed many ways the Silk Road site facilitated the illegal drug trade all over the world and how Ulbricht ran his criminal organization. SA DerYeghiayan served as the lead witness for the government in the Silk Road trial.
- In an economy where the demand—drug-addicted users—remains constant or growing, that’s only to be expected.
- A screenshot of the marketplace shared by the DOJ in the statement showed cocaine available for bulk purchase from JoyInc on Drughub, a dark web site.
- A new, technically advanced market called White House has also been launched, gaining 10,000 listings, 100,000 users and many trusted vendors.
- Australia is a leading country in the darknet drugs trade, with more online drug vendors per capita than any other nation except the Netherlands, according to research presented at this week’s Victorian Alcohol and Drug Association Conference.
- Our experiment evaluated MALLET on our annotated anonymous marketplace and forum data set (Table 3) using 3 classification algorithms in the document classification tool (package cc.mallet.classify class in MALLET’s JavaDoc API Application Programming Interface).
Australia Emerges As A Leader In The Global Darknet Drugs Trade
Upon visiting the site via the Tor browser, users were greeted by a graphic interface and prompted to log in with a unique username and password. Inside, buyers could browse thousands of drug listings, many accompanied by reviews and ratings. The platform also featured prescription drug listings falsely marketed as authentic, and some products were outright scams—counterfeit pills advertised as legitimate pharmaceuticals. The firm has been on a major recruiting drive for casual mail-sorting staff, leading to increased delivery capacity and delivery speed, helping darknet markets make millions. At the height of lockdown, mail-sorting offices were over-run, short-staffed and swamped with millions of extra parcels as online sales boomed.
A screenshot of the marketplace shared by the DOJ in the statement showed cocaine available for bulk purchase from JoyInc on Drughub, a dark web site. Four Los Angeles County men were arrested Wednesday on suspicion of operating one of the dark web’s biggest drug distribution networks, according to the U.S. It seized 50.8 million euros ($53.4 million) in cash and virtual currencies, 850 kilograms of drugs, and 117 firearms were seized in a series of raids in several countries.

Instead, they must gain access to multiple, hyper-secure markets and then regularly monitor this wide array of smaller, highly localized platforms. Further confounding efforts, these multiple markets are often scattered across different regions and jurisdictions, requiring significant international cooperation to drive operations. In 2025, agencies will need to deploy a combination of advanced cyber tools, including AI-driven pattern recognition, blockchain analysis, and network infiltration strategies, to track illicit activity across multiple channels. Studying illicit drug circulation and its effects on population health is complicated due to the criminalization of trade and consumption.
It marks the most significant JCODE operation to date, building on years of enforcement actions and marketplace takedowns, including Kingdom Market, Tor2Door, Bohemia, and Nemesis. Many users extended escrow to allow for late deliveries, and one crew went so far as to refund users – to the last satoshi the smallest unit of a bitcoin – when packs did not arrive. After all, darknet markets are remarkably self-regulating systems, based on anarchist principles.
JCODE is an FBI-led Department of Justice initiative, which supports, coordinates, and assists in de-confliction of investigations targeting for disruption and dismantlement of the online sale of illegal drugs, especially fentanyl and other opioids. JCODE also targets the trafficking of weapons and other illicit goods and services on the internet. The seizures, to which ICE Homeland Security Investigations significantly contributed, include more than $200 million in currency and digital assets, over two metric tons of drugs, comprised of 144 kilograms of fentanyl or fentanyl-laced narcotics, and over 180 firearms. In addition, the United States and international law enforcement partners made 270 arrests of dark web vendors, buyers, and administrators in Austria, Brazil, France, Germany, Netherlands, South Korea, Spain, Switzerland, United Kingdom, and the United States. Recent estimates put the cryptomarkets as a substantial but definite minority of the drug market overall, worth around €750,000 Euro per day for sites serving European locations 21.
Opioid Trading Information Retrieval
Thus, we could estimate the dynamics of market scene changes during a relatively extended period. All these conditions theoretically support the anonymity and safety of the business. The mandatory barring of leaving houses for people during the COVID-19 disaster limited the supply of drugs in Russia. We do not have monthly data on drug poisoning, but we found significant correlations with this variable in yearly data.
Mackey et al 13 collected tweets related to the opioid topic to identify illicit online pharmacies and study the illegal sale of opioids in online marketing. Cherian et al 12 gathered codeine misuse data from Instagram posts to understand how misuse is happening and its misused form. Recently, Balsamo et al 11 used a language model to expand vocabularies for opioid substances, routes of administration, and drug tampering on Reddit data from 2014 to 2018 and investigated some important consumption-related aspects of the nonmedical abuse of opioid substances. However, to the best of our knowledge, no large-scale study, which may cross multiple anonymous marketplaces and is cross-sectional, has been conducted to profile the opioid supply chain and unveil characteristics of opioid suppliers, commodities, and transactions. First, we designed and implemented an anonymous marketplace data collection and analysis pipeline to gather and identify opioids data in 16 anonymous marketplaces and forums over a period of almost 9 years between 2011 and 2020. Second, we fine-tuned the semantic comparison model proposed by Yuan et al 19 for opioid jargon detection, which can recognize the opioid jargon as innocent-looking terms and the dedicated terms only used in the anonymous marketplaces and forums.
