RESUMO

BACKGROUND: Personal vaporisers are gaining popularity as an alternative route of administration for a range of substances. Online cryptomarkets are becoming increasingly popular among people who use substances due to their perceived anonymity, ease of use, and reduced risk of violence compared to traditional face-to-face dealers. We examined the diversity of substances marketed for use in a personal vaporiser on these marketplaces. METHODS: Vaping related listings were extracted from three online cryptomarkets ('Agartha', 'Cryptonia', and 'Tochka') using The Onion Router browser. Data collection occurred between October and November 2019. RESULTS: We identified 1929 listings from 201 unique sellers. The top product on Agartha, Cryptonia, and Tochka were vape cartridges prefilled with the e-liquid (70.4 %, 39.4 %, 52.3 % respectively). The most common substance in these products was cannabis oil (96.1 %, 82.1 %, 87.8 %), followed by synthetic cannabinoids (3.7 %, 9.7 %, 9.8 %) and psychedelic substances (0.2 %, 6.4 %, 1.2 %). Vendors were primarily from the USA. Many products offered worldwide shipping (96.3 %, 42.4 %, 51.2 %). CONCLUSION: Vaping products listed on online cryptomarkets in 2019 primarily contained cannabis oils. Future studies should continue to examine cryptomarkets to identify emerging trends of substances that can be used in personal vaporisers.

RESUMO

: The COVID-19 pandemic and the response to have resulted in an increase in sales activity levels on darknet markets during the first 3 months of 2020, mainly related to cannabis products. One key question is whether more people will become used to this form of purchasing their drugs and will they continue with it post COVID-19 lockdown. As one-to-one encrypted communication services or social media apps are increasingly being used, monitoring and interdiction will become much more challenging.

RESUMO

BACKGROUND: Illicitly manufactured fentanyl and its analogues are appearing in countries throughout the world, often disguised as heroin or counterfeit prescription pills, with resulting high overdose mortality. Possible explanations for this phenomenon include reduced costs and risks to heroin suppliers, heroin shortages, user preferences for a strong, fast-acting opioid and the emergence of Dark Web cryptomarkets. This paper addresses these potential causes and asks three questions: (1) can users identify fentanyl; (2) do users desire fentanyl; and (3) if users want fentanyl, can they express this demand in a way that influences the supply? ARGUMENT/ANALYSIS: Existing evidence, while limited, suggests that some users can identify fentanyl, although not reliably, and some desire it, but because fentanyl is frequently marketed deceptively as other drugs, users lack information and choice to express demand effectively. Even when aware of fentanyl's presence, drug users may lack fentanyl-free alternatives. Cryptomarkets, while difficult to quantify, appear to offer buyers greater information and competition than offline markets. However, access barriers and patterns of fentanyl-related health consequences make cryptomarkets unlikely sources of user influence on the fentanyl supply. Market condition data indicate heroin supply shocks and shortages prior to the introduction of fentanyl in the United States and parts of Europe, but the much lower production cost of fentanyl compared with heroin may be a more significant factor CONCLUSION: Current evidence points to a supply-led addition of fentanyl to the drug market in response to heroin supply shocks and shortages, changing prescription opioid availability and/or reduced costs and risks to suppliers. Current drug users in affected regions of the United States, Canada and Europe appear largely to lack both concrete knowledge of fentanyl's presence in the drugs they buy and access to fentanyl-free alternatives.

RESUMO

Background Crackdowns on urban sites with concentrated criminal activity are sometimes followed by geographical relocation of crime. Is this also the case in cyberspace, where illegal websites and online networks can be wiped clean, but also quickly rebuilt and replaced on new servers and URLs? Methods I address this question in three steps. First, I measure MDMA trade in a large digital market for drugs, before and after the arrest of a leading MDMA seller in the same market. Second, I count the number of available digital drug markets and vendor shops in the period February 2014-June 2018, to see if websites closed by police were replaced by new ones. Third, I track the digital movement and trading activities of individual drug sellers, before and after law enforcement shut down two large markets. Results After police arrested a leading MDMA seller, other MDMA sellers filled most - but not all - of the gap. A major law enforcement crackdown reduced the number of available markets, but new ones were created, and market counts eventually surpassed the previous peak. When law enforcement shut down two big markets, many of the sellers relocated to other e-commerce sites and continued high-earning operations there. Conclusion Arrests and market closures redirect digital drug trade to other sellers and markets. Hot spot policing in cyberspace might produce temporary results, but is arguably ineffective in the long run, as actors use information and communication technology's unique capacities to reorganize.

RESUMO

INTRODUCTION: Cryptomarkets operating on the darknet are a recent phenomenon that has gained importance only over the last couple of years (Barratt, 2012). However, they now constitute an evolving part of illicit drug markets. Although selling and buying a variety of psychoactive substances on the Internet has a long history, new technological developments enable systematic drug trading on the net.These technological innovations on the Internet allow users to proceed with (illicit) drug transactions with almost completely anonymous identities and locations. In this paper, we provide a systematic measurement analysis of structures and trends on the most popular anonymous drug marketplace, and discuss the role of cryptomarkets in drug distribution. METHODS: Data collection and analysis include a long-term measurement of the cryptomarket 'AlphaBay', the most popular platform during the survey period. By developing and applying a web-scraping tool, market data was extracted from the marketplace on a daily basis during a period of twelve months between September 2015 and August 2016. The data was analysed by using business-intelligence software, which allows the linking of various data sets. We found 2188 unique vendors offering 11,925 drug items. The findings of our long-term monitoring and data analysis are compared over time and across marketplaces, offering a detailed understanding of the development of revenues generated, characterisation of countries of origin and destination, and distribution of vendors and customers over time. RESULTS: We provide a nuanced and highly detailed longitudinal analysis of drug trading on the darknet marketplace 'AlphaBay', which was the largest cryptomarket in operation. 1) Total sales volumes for the 'drugs' section was estimated at approximately USD 94 million for the period from September 2015 to August 2016. 2) In addition, about 64% of all sales are made with cocaine-, cannabis-, heroin-, and ecstasy-related products. 3) Average selling prices increase over time for categories including cannabis and hashish, ecstasy, opioids, psychedelics and stimulants. 4) The five most frequent countries of origin as indicated by vendors are the United States, United Kingdom, Australia, the Netherlands and Germany. Moreover, it was demonstrated that drug distribution on cryptomarkets is conducted at a regional rather than global level. 6) Furthermore, 4.88% of vendors made over USD 200,000 and were responsible for 52.9% of total revenues generated over the period analysed. In contrast, 57.51% of vendors managed to sell drug items worth less than USD 10,000 within a period of twelve months. The findings suggest that 'AlphaBay' was a cryptomarket mainly from and for Western industrialised countries. In contrast, countries of the global South are neither among the main countries of origin nor destination countries.

RESUMO

Prior research has documented the availability of drugs on many Tor Network websites, with the Internet playing a particularly vital role in the global new psychoactive substances (NPS) market. The primary objective of this research was to document types of NPS for sale on the largest operating Tor site (Agora) over a period of four months. Secondary objectives were to analyze countries and vendors sourcing NPS on Agora. Data from Agora were collected in February and June 2015. The number of total advertisements on Agora increased from 20,742 to 27,431 over the four months, while the number of NPS advertisements increased from 2,205 to 2,271 and the number of vendors increased from 157 to 288. The composition of NPS listings and source countries for NPS advertised on Agora diversified over time. Advertisements for ketamine and unclassified NPS experienced substantial growth, while the availability of phenethylamines decreased. However, phenethylamines remained the most frequently advertised NPS type. China and the U.S. were found to be the top two countries by volume selling NPS on Agora over the fpir months, but the number of countries identified as advertising NPS increased by nearly 43%. The United States housed the most NPS vendors.

RESUMO

BACKGROUND: Dread Pirate Roberts, founder of the first cryptomarket for illicit drugs named Silk Road, articulated libertarian political motives for his ventures. Previous research argues that there is a significant political component present or involved in cryptomarket drug dealing which is specifically libertarian. The aim of the paper is to investigate the prevalence of political discourses within discussions of cryptomarket drug dealing, and further to research the potential changes of these over the timespan of the study. METHODS: We develop a novel operationalization of discourse analytic concepts which we combine with topic modelling enabling us to study how politics are articulated on cryptomarket forums. We apply the Structural Topic Model on a corpus extracted from crawls of cryptomarket forums encompassing posts dating from 2011 to 2015. RESULTS: The topics discussed on cryptomarket forums are primarily centered around the distribution of drugs including discussions of shipping and receiving, product advertisements, and reviews as well as aspects of drug consumption such as testing and consumption. However, on forums whose primary function is aiding operations on a black market, we still observe political matter. We identified one topic which expresses a libertarian discourse that emphasizes the individual's right to non-interference. Over time we observe an increasing prevalence of the libertarian discourse from 2011 to the end of 2013. In the end of 2013 - when Silk Road was seized - we observe an abrupt change in the prevalence of the libertarian discourse. CONCLUSIONS: The libertarian political discourse has historically been prevalent on cryptomarket forums. The closure of Silk Road has affected the prevalence of libertarian discourse suggesting that while the closure did not succeed in curtailing the cryptomarket economy, it dampened political sentiments.

RESUMO

The objective of the present study was to examine trends and correlates of handgun carrying among adolescents ages 12-17 in the United States. Data was derived from the National Survey on Drug Use and Health (NSDUH) involving non-Hispanic White, African American, and Hispanic respondents ages 12-17 (n=197,313) and spanning the years 2002-2013. Logistic regression was used to examine significance of trend year and correlates of previous 12-month handgun carrying. The overall self-reported prevalence of handgun carrying was 3.4%. The prevalence of handgun carrying during 2004-2005 was significantly higher for African-Americans (4.39%) compared to non-Hispanic Whites (3.03%). However, by 2012-2013, non-Hispanic Whites (4.08%) completely diverged and reported carrying handguns significantly more than both African-American (2.96%) and Hispanic (2.82%) youth. Male gender and a number of externalizing behaviors were significant correlates of handgun carrying; however, we also found evidence of differential correlates with regard to such factors as drug selling, parental affirmation, and income by race/ethnicity. To our knowledge, this is the largest study of handgun carrying among youth in the United States. Findings indicate that although at historically low levels handgun carrying is on the rise but only among non-Hispanic Whites. Differential correlates among racial/ethnic groups suggest prevention programming and policies may need modifications depending on group and geographic locale targeted.

RESUMO

BACKGROUND: International drug law enforcement agencies have identified an apparent rise in high level drug traffickers choosing to deal in multiple different drugs. It is hypothesised that this may be a "deliberate modus operandi" and that the formation of "portfolios of trades" may make such traffickers more profitable, harmful and resilient to changes in drug supply and policing. In this paper we provide the first exploration of the extent, nature and harms of poly-drug trafficking at Australian borders. METHODS: Two different methods were used. First, we used Australian Federal Police (AFP) data on all commercial level seizures at the Australian border from 1999 to 2012 to identify the proportion of seizures that were poly-drug and trends over time. Second, we used unit-record data on a sub-set of 20 drug trafficking cases and linked-cases (defined as the original drug trafficking case and all other criminal cases that were connected via common offenders and/or suspects) to compare the profiles of poly-drug and mono-drug traffickers, including: the total weight and type of drug seized, the value of assets seized, and the level of involvement in other crime (such as money laundering and corruption). RESULTS: Between 5% and 35% of commercial importations at the Australian border involved poly-drug trafficking. Poly-drug trafficking occurred in almost every year of analysis (1999-2012), but it increased only slightly over time. Compared to mono-drug traffickers poly-drug traffickers were characterised by: larger quantities of drugs seized, larger networks, longer criminal histories and more involvement in other types of serious crime. CONCLUSION: Some fears about poly-drug traffickers may have been overstated particularly about the inherent escalation of this form of trafficking. Nevertheless, this suggests poly-drug traffickers are likely to pose added risks to governments and law enforcement than mono-drug traffickers. They may necessitate different types of policy responses.
