Disruption to Australian heroin, methamphetamine, cocaine and ecstasy markets with the COVID-19 pandemic and associated restrictions.

BACKGROUND: Changes to drug markets can affect drug use and related harms. We aimed to describe market trends of heroin, methamphetamine, cocaine and ecstasy in Australia following the introduction of COVID-19 pandemic-associated restrictions. METHODS: Australians residing in capital cities who regularly inject drugs (n ∼= 900 each year) or regularly use ecstasy and/or other illicit stimulants (n ∼= 800 each year) participated in annual interviews 2014-2022. We used self-reported market indicators (price, availability, and purity) for heroin, crystal methamphetamine, cocaine, and ecstasy crystal to estimate generalised additive models. Observations from the 2014-2019 surveys were used to establish the pre-pandemic trend; 2020, 2021 and 2022 observations were considered immediate, short-term and longer-term changes since the introduction of pandemic restrictions. RESULTS: Immediate impacts on market indicators were observed for heroin and methamphetamine in 2020 relative to the 2014-2019 trend; price per cap/point increased (ß: A$9.69, 95% confidence interval [CI]: 2.25-17.1 and ß: A$40.3, 95% CI: 33.1-47.5, respectively), while perceived availability (adjusted odds ratio [aOR] for 'easy'/'very easy' to obtain: 0.38, 95% CI: 0.24-0.59 and aOR: 0.08, 95% CI: 0.03-0.25, respectively) and perceived purity (aOR for 'high' purity: 0.36, 95% CI: 0.23-0.54 and aOR: 0.33, 95% CI: 0.20-0.54, respectively) decreased. There was no longer evidence for change in 2021 or 2022 relative to the 2014-2019 trend. Changes to ecstasy and cocaine markets were most evident in 2022 relative to the pre-pandemic trend: price per gram increased (ß: A$92.8, 95% CI: 61.6-124 and ß: A$24.3, 95% CI: 7.93-40.6, respectively) and perceived purity decreased (aOR for 'high purity': 0.18, 95% CI: 0.09-0.35 and 0.57, 95% CI: 0.36-0.90, respectively), while ecstasy was also perceived as less easy to obtain (aOR: 0.18, 95% CI: 0.09-0.35). CONCLUSION: There were distinct disruptions to illicit drug markets in Australia after the COVID-19 pandemic began; the timing and magnitude varied by drug.

"The Drug Sellers Were Better Organized than the Government": A Qualitative Study of Participants' Views of Drug Markets during COVID-19 and Other Big Events.

"Big events", such as wars, economic crises, pandemics, or natural disasters, affect the risk environment in which people use drugs. While the impact of big events on injection risk behaviors and access to drug-treatment services is well documented, less is known about the effects of big events on drug markets. Based on self-reporting data on drug availability among people who use drugs (PWUD) in the aftermath of Hurricane Maria in Puerto Rico and during the COVID-19 lockdown in a Midwestern US state, this study aims to document the effects of big events on drug markets. Qualitative data on the effects of Hurricane Maria on drug markets are based on participants' self-reporting (N = 31). Data collection started after the hurricane and ended in 2020. Data on changes to the drug supply during the COVID-19 lockdown were collected based on semi-structured interviews with PWUD (N = 40) in a Midwestern US state. Findings show that while the drug markets might have initially been affected by big events, most effects were temporary. Drug availability, pricing, and quality might have suffered some initial fluctuations but stabilized as the drug markets absorbed the initial shocks caused by the hurricane and the lockdown measures. In preparation for increasingly more frequent and virulent pandemics and natural disasters, health infrastructures should be strengthened to prevent not only overdose episodes and deaths but also drug-related harms.

The impact of COVID-19 on people who inject drugs in New York City: increased risk and decreased access to services.

BACKGROUND: While people who inject drugs (PWID) are vulnerable to the adverse outcomes of events like COVID-19, little is known regarding the impact of the current pandemic on PWID. We examine how COVID-19 has affected PWID in New York City across four domains: substance use, risk behaviors, mental health, and service utilization. METHODS: As part of a randomized trial to improve access to HCV treatment for PWID, we recruited 165 participants. Eligibility criteria included detectable HCV RNA and recent drug injection. The present cross-sectional analysis is based on a subsample of 106 participants. We compared responses between two separate samples: 60 participants interviewed prior to the pandemic (pre-COVID-19 sample) and 46 participants interviewed during the pandemic (COVID-19 sample). We also assessed differences by study group [accessible care (AC) and usual care (UC)]. RESULTS: Compared to the pre-COVID-19 sample, those interviewed during COVID-19 reported higher levels of mental health issues, syringe reuse, and alcohol consumption and greater reductions in syringe-service programs and buprenorphine utilization. In the analysis conducted by study group, the UC group reported significantly higher injection risk behaviors and lower access to buprenorphine treatment during COVID-19, while during the same period, the AC group reported lower levels of substance use and injection risk behaviors. CONCLUSION: The current study provides insight on how COVID-19 has negatively affected PWID. Placing dispensing machines of harm-reduction supplies in communities where PWID live and increasing secondary exchange, mobile services, and mail delivery of supplies may help maintain access to lifesaving supplies during big events, such as COVID-19.

Emerging Zoonotic Infections, Social Processes and Their Measurement and Enhanced Surveillance to Improve Zoonotic Epidemic Responses: A "Big Events" Perspective.

Zoonotic epidemics and pandemics have become frequent. From HIV/AIDS through COVID-19, they demonstrate that pandemics are social processes as well as health occurrences. The roots of these pandemics lie in changes in the socioeconomic interface between humanity and non-human host species that facilitate interspecies transmission. The degree to which zoonoses spread has been increased by the greater speed and extent of modern transportation and trade. Pre-existing sociopolitical and economic structures and conflicts in societies also affect pathogen propagation. As an epidemic develops, it can itself become a social and political factor, and change and interact with pre-existing sociobehavioral norms and institutional structures. This paper uses a "Big Events" approach to frame these processes. Based on this framework, we discuss how social readiness surveys implemented both before and during an outbreak might help public health predict how overall systems might react to an epidemic and/or to disease control measures, and thus might inform interventions to mitigate potential adverse outcomes or possibly preventing outbreaks from developing into epidemics. We conclude by considering what "pathways measures", in addition to those we and others have already developed, might usefully be developed and validated to assist outbreak and epidemic disease responses.

Socially-supportive norms and mutual aid of people who use opioids: An analysis of Reddit during the initial COVID-19 pandemic.

BACKGROUND: Big events (i.e., unique historical disruptions) like the COVID-19 epidemic and its associated period of social distancing can transform social structures, social interactions, and social norms. Social distancing rules and the fear of infection have greatly reduced face-to-face interactions, increased loneliness, reduced ties to helping institutions, and may also have disrupted the opioid use behaviors of people who use drugs. This research used Reddit to examine the impact of COVID-19 on the social networks and social processes of people who use opioids. METHODS: Data were collected from the social media forum, Reddit.com. At the beginning of the COVID-19 pandemic in the U.S. (March 5, 2020, to May 13, 2020), 2,000 Reddit posts were collected from the two most popular opioid subreddits (r/OpiatesRecovery, r/Opiates). Posts were reviewed for relevance to COVID-19 and opioid use resulting in a final sample of 300. Thematic analysis was guided by the Big Events framework. RESULTS: The COVID-19 pandemic was found to create changes in the social networks and daily lives among persons who use opioids. Adaptions to these changes shifted social networks leading to robust social support and mutual aid on Reddit, including sharing and seeking advice on facing withdrawal, dealing with isolation, managing cravings, and accessing recovery resources. CONCLUSIONS: Reddit provided an important source of social support and mutual aid for persons who use opioids. Findings indicate online social support networks are beneficial to persons who use opioids, particularly during big events where isolation from other social support resources may occur.
