Buying Heroin Eastern District

The illicit drug trade generates billions of dollars and sustains transnational criminal organisations. Drug markets can destabilise governance and undermine development. Data indicate increasing drug use in South Africa. However, information on the size and value of the drug market is limited. This is the first study to estimate the market value of cocaine, heroin and methamphetamine in South Africa. People who use drugs were meaningfully involved in all aspects of implementation. We used focus group discussions, ethnographic mapping, brief interviews, and the Delphi method to estimate the number of users, volumes consumed, and price for each drug in South Africa in Nationally, we estimated there to be: , people who use heroin probability range PR ,—, consuming Findings can be used to stimulate engagement to reform drug policy and approaches to mitigate the impact of the illicit drug trade. Additional studies that include people who use drugs in research design and implementation are needed to improve our understanding of drug markets. The illicit drug market is big. Over the past decade there has been marked growth in the size of the drug market around the world United Nation Office on Drugs and Crime Prohibitionist approaches have had little to no meaningful impact on drug supply or demand The Global Commission on Drug Policy Between and , seizure of opioids and amphetamine type stimulants ATS increased more than two-fold, with less marked increases in cocaine seizures UNODC In comparison, global production of opium and cocaine roughly doubled over the past two decades and supply has remained relatively stable UNODC Paradoxically, efforts to control drug supply through seizures and drug-related arrests may increase profitability through reduced competition and increased demand Bouchard Flexible and changing transportation solutions are employed by actors involved in the illicit drug trade to mitigate the potential effects that geopolitical events and law enforcement may have on business UNODC ; Eligh , Globally, in an estimated 62 million people used opioids for non-medical purposes, 27 million people used ATS and 20 million people used cocaine UNODC In , the annual prevalence of cannabis use among people in Africa was 6. The valuation of drug markets requires data on volumes and price. However, the criminalised nature of drug use and the drug market complicates valuation. For example, the volume of drugs traded is sometimes calculated by extrapolating police seizure data Werb et al. Furthermore, estimates of the number of people who use drugs are largely lacking or inaccurate UNODC Many existing estimates are taken from household surveys. However, sub-populations of people with higher proportions of drug use e. Moreover, under reporting of drug use in household surveys is common due to fear of arrest, stigma, and poor questionnaire design Johnson ; Global HIV Strategic Information Working Group et al. Health service data can provide insights into trends, but it is limited to those who access treatment UNODC Drug-related arrest data is also of limited value to assist our understanding of drug demand. Incentives for arrest, the differential likelihood of detention based on demographic and socioeconomic characteristics, and political and legal factors influence policing practices, resulting in biased estimates Lukas Muntingh ; Mooney et al. Similarly, it is difficult to assess the amount of drugs consumed. Estimates may be based on data collected through the approaches noted above; however, the data would likely be affected by the same biases affecting other variables. Drug market valuation estimates are more easily based on consumer price, as wholesale prices are rarely known European Monitoring Centre for Drugs and Drug Addiction However, consumer prices may fluctuate and are influenced by purity and the addition of bulking agents Cole et al. Specialised methodologies can overcome the challenges noted above. For example, research conducted in partnership with people who use drugs and trusted organisations using recommended methods e. Novel analytical techniques, such as sewage epidemiology, can be used to assess drug metabolite levels in wastewater to provide empirical insights into the volume of drugs consumed Huizer et al. Emerging data point to a large, and growing drug market in South Africa Eligh Increasing flows of heroin, 1 cocaine, and methamphetamine have been documented over the past 20 years Haysom In , 0. A household survey found that 0. Drug market research reflects a net decrease in the price of heroin, cocaine, and methamphetamine between and Howell et al. In light of the increased volume of drugs flowing through the country, and increasing use, it is probable that the illicit drug economy is of significant size and value. This study aimed to estimate the retail market value of cocaine, heroin, and methamphetamine in South Africa from a demand side, with meaningful engagement and participation of people who use drugs. The study employed focus group discussions FGDs , ethnographic mapping, brief interviews, and the Delphi method to gather inputs to estimate the retail drug market value in South Africa in South Africa has nine provinces and is comprised of 52 districts. Districts are further divided into electoral wards. The most populous city in each selected province was selected for implementation. No cities were included from the North West and Northern Cape Provinces, which do not have metropolitan municipalities and are the third least and least populous provinces. Activities took place between May and November People who use drugs facilitated FGDs and ethnographic mapping activities, conducted interviews, validated the results, and participated in population size estimation workshops. Broadly, the procedures involved: 1 primary data collection FGDs, mapping and brief interviews with people who use drugs and validation sessions; 2 population size estimation using the Delphi Method provincial and national workshops and 3 market valuation. National and local stakeholders were informed of the project. In the cities where fieldwork took place, engagements focused on networks of people who use drugs and organisations providing health and harm-reduction services for people who use drugs, men who have sex with men, transgender people, and sex workers key populations. Engagement activities sought to obtain support for the study. Engagement with other stakeholders e. Primary data collection and validation sessions were held in each city. Table 1 provides details of primary data collection and validation activities. Fieldwork was done sequentially over 3—5 days in each city. Fieldworkers, identified during FGDs, underwent a half-day training on the study, covering: conducting brief interviews with their peers using standard tools; data quality; ethical considerations; safety and COVID mitigation strategies. Activities were piloted in each city before implementation. At the end of the fieldwork in each city, structured validation sessions were held to reach agreement on 1 the cost of each drug per gram ; 2 average amount a range, in grams of each drug used in a hour period; 3 proportion of daily and infrequent monthly users of each drug, and 4 population size estimates for each drug and for people who inject for the city. This process involved a bottom up-approach, building on the city-level estimates from the fieldwork to develop district, then provincial and finally national population estimates. Provincial workshops : Fieldwork team members, representatives of people who use drugs networks and local stakeholders including health service providers participated in virtual provincial estimation workshops. Seven workshops were held. Participants interrogated the city-level estimates from the validation sessions in light of programmatic and research data and their experience. The group reached consensus on district-level estimates and upper and lower plausibility bounds using the Delphi Method Jorm This method employs four rounds of facilitated engagement among experts to reach consensus on estimates. Estimates were generated for the number of people who use cocaine, heroin, and methamphetamine, and the number who inject drugs in the respective fieldwork district reference district. The district-level estimates were then used to generate proportions of people in that district aged 15—64 who use each drug and those who inject drugs using the most recent census data Statistics South Africa Provincial workshop participants ordered the districts in their province from the district with the largest population of people who use drugs to the smallest. Agreement was reached on the relative size of each district in relation to the reference district in that province. The relevant size was calculated as an adjustment proportion. Adjustment proportions were then applied to the general population estimate 15—64 years of the districts that were not visited in that province. The same adjustment factor was applied across each drug type. This process resulted in district-level estimates for each drug and for people who inject drugs in the province. All of the district estimates were summed to generate initial national population estimates point estimates and lower and upper plausibility bounds. National workshops: The research team convened a virtual national size estimation workshop over two sessions held a week apart. Participants included people who use drugs, key population representatives, development partners, researchers, health workers, social workers, government representatives, and civil society service providers. The first session was used to review the process and participants interrogated the findings of the fieldwork and the initial national population estimates i. During the second workshop, the process, fieldwork findings, and other available data were recapped and the Delphi method was used to obtain revised national population estimates. The retail market value was calculated by multiplying total annual consumption by price European Monitoring Centre for Drugs and Drug Addiction Annual consumption was calculated separately for the population of people who used drugs daily and those who used drugs infrequently assumed to be once a month. These values were added to estimate total annual consumption. Figure 1 provides the formula used and data inputs. Formula and data inputs to calculate the retail drug market value European Monitoring Centre for Drugs and Drug Addiction, Procedures, tools, and training were standardised. Fieldworkers and the research coordinator completed reviews of forms for completeness. Paper forms and written notes were concealed while in the field and securely stored. Neither personal nor detailed location data was captured. Summary statistics were generated to describe fieldwork participants and quantitative indicators. The market value was calculated using the formula outlined above. Verbal informed consent was obtained. Overall, people who use drugs men, women, and 14 transgender people participated in brief interviews across locations in wards. People who used heroin had the largest peer network median of 40 people , and people who used methamphetamine had the smallest median of 20 people. A total of people who use drugs participated in validation workshops. A validation workshop was not completed in Pietermaritzburg due to logistical complications. Table 2 outlines fieldwork participant characteristics. FGD participants reported that heroin, crack, and powder cocaine and methamphetamine were available and used in all the cities where fieldwork was conducted. They suggested that most people who use heroin concurrently used stimulants, either methamphetamine in Cape Town and Port Elizabeth or crack cocaine in the other cities. FGD participants believed that more than half the people who use heroin inject it, while crack cocaine and methamphetamine are mostly smoked, and powder cocaine snorted. Injecting methamphetamine was reported to be more common when mixed with heroin. However, some people were reported to inject methamphetamine on its own. Across the cities, an average of 10—30 people were observed at each hotspot where brief interviews were conducted. Generally speaking, interviewees reported that between 25 and 60 people congregated at these locations at their busiest times. Heroin was reported to be used by almost all people at the hotspots, except in Cape Town, where methamphetamine was the most widely used drug. Injecting was reported across the hotspots in all visited cities except for Bloemfontein, although injecting practices were confirmed in the validation session in that city. The validated estimates for population sizes, proportion of people with daily and infrequent use, amounts used in a day and the cost of each drug arising from the fieldwork are provided in Table 3. Details of the fieldwork districts population proportions are in Supplementary Table S1 and the adjustment factors and the population size estimates for all districts and the initial and revised Delphi national population size estimates are provided in Supplementary Table S2. District-level estimates fieldwork districts : population size estimates, frequency and amounts used and unit cost per drug, by city. Among people who inject heroin, daily amounts were reported to range from 0. Amounts of reported cocaine used varied across cities. For crack cocaine, this ranged from 0. For powder cocaine, amounts used per day ranged from 0. Data was not obtained for the frequency of methamphetamine use in Pietermaritzburg. Amounts of methamphetamine reported to be used per day ranged from 0. The national level market value inputs and results are presented in Table 4. The median amount used in a hour period 0. For methamphetamine, two-thirds of users were assumed to use daily. The median amount used in 24 hours was assumed to be 0. Daily cocaine amounts is based on crack cocaine, which is around a third less than suggested daily powder cocaine amounts. The crack cocaine daily amount was chosen due to limited participation of powder cocaine users in the research. The national population size estimate of the number of people who use heroin was , probability range PR ,—, , consuming tonnes PR The population estimate for people who use cocaine was , including , daily users , consuming The number of people who use methamphetamine was estimated at , including , daily users consuming This study was designed to assess the retail value of a criminalised and unregulated market. To the best of our knowledge the research is the first of its kind in South Africa. The study used practical methods to gather inputs to impute into a recommended drug market valuation formula European Monitoring Centre for Drugs and Drug Addiction The study provides initial estimates which can be included in future studies towards an accurate estimation of the drug market value in the country. The findings suggest that the nature and size of the drug market in South Africa are significant. The International Narcotics Control Board notes that in there was limited data on drug trafficking in Africa, but it remains a major challenge on the continent International Narcotics Control Board The ongoing trafficking of cocaine mostly in West and North Africa and heroin in the Indian Ocean region and increasing market size is acknowledged, along with small drug seizures reported in International Narcotics Control Board There is little data on the value of drug markets in other African contexts. The International Narcotics Control Board estimated that 2. Superior data is available for Europe. Our estimates for South Africa have wide plausibility ranges. This is largely due to uncertainty around the population size estimates. The fieldwork identified widespread use of cocaine, heroin, and methamphetamine across the cities included in the study. Our best estimates for population size estimates for people who used drugs in was 3. The household survey is likely to be subject to selection and reporting bias, and therefore an underestimate. The degree of underestimation of drug use in household surveys in South Africa is difficult to assess as people who use heroin, methamphetamine, and cocaine face arrest and are affected by intersectional stigmas that create barriers to disclosing drug use Shelly et al. Estimating population sizes is known to be challenging, and recommended practice is for the use of multiple empirical methods Global HIV Strategic Information Working Group et al. Mapping with census and enumeration, capture-recapture, multiplier methods, and Wisdom of the Crowds are some of the recommended methods that can be integrated into biobehavioural surveys for people who use drugs Global HIV Strategic Information Working Group et al. We used the key informant-driven mapping and enumeration approach Ndayongeje et al. The fieldwork was based on the premise that meaningfully involving people who use drugs through a participatory action research approach would reduce some potential bias of household surveys Brown et al. Although limited in application, people who use drugs have generated bottom-up estimates in South Africa Scheibe et al. An increased number of studies has documented the spread and increased use of heroin in South Africa and the region since the early s Eligh The evidence base from research and programme data consistently shows upward trends in the prevalence of heroin use across the country. Increased cocaine use, particularly crack cocaine, has also been described. In the early s the use of methamphetamine started to increase Peltzer et al. Methamphetamine surpassed cocaine as a proportion of primary drug of use among people in drug treatment centres in Dada et al. Methamphetamine-related admissions to drug treatment centres have continued to rise Dada et al. The wide availability of methamphetamine was confirmed by our fieldwork. Data from sewage epidemiology in South Africa suggest notable underestimation of drug use. For example, the levels of methamphetamine metabolites in wastewater in Cape Town are among the highest levels documented, higher than cities in Europe and Malaysia Archer et al. Insights from a large number of people who currently use drugs elicited through focus groups and validation meetings give us confidence in the drug pricing estimates. The cost of drugs varied across cities and was generally lower than prices based on data from the police. The relative costs per gram of each drug is likely to reflect a combination of factors, including the quantities available for sale, user preferences, and drug quality. The findings of this study suggest that larger volumes of heroin are used compared to the other drugs included in this study in South Africa. It is possible that we have over-estimated the number of people who use drugs and the proportion of people who use drugs daily. This may have resulted in over-valuation of the drug market. However, in light of the improbability and cost of implementing a national census of people who use drugs and the limited available quantitative data we believe the use of the Delphi Method was justifiable. Furthermore, the use of the Delphi Method in our study was efficient and enabled virtual participation. It also built on fieldwork and other limited data and inputs from experts in a range of fields, including people who use drugs and harm reduction service providers. This study did not measure perceived drug quality or drug purity. Drug quality and purity potentially influences drug cost in South Africa and may differ across the country and in relation to other countries Eligh Heroin prices in southern African have been found to be largely influenced by availability, transport costs, and to a lesser degree, perceived quality Eligh The resources available for implementation limited the number of implementation sites. The inclusion of more fieldwork sites would have provided additional primary data and reduced the degree of extrapolation applied to districts where primary data was not collected. Additional implementation sites and primary data would have likely increased the accuracy of the estimates. The fieldwork was designed to include people who are often missed or excluded from surveys, specifically people living on the street. Therefore, it is likely that more affluent people who use drugs were under-represented in data drawn from the fieldwork. Due to their higher income and the perceived relationship between quality and price, it is conceivable that the market value of this segment could be even higher than the total market size reported in this study. Potential under-representation of people who use drugs was taken into consideration in the Delphi process and was deemed to be of particular importance for powder cocaine. Participation of more affluent people in future drug market related research could be enhanced through the use of digital platforms to collect data, providing confidentiality is ensured. The participation of drug sellers could also provide additional insights into other segments of the population of people who use drugs. The concurrent COVID pandemic and associated lockdowns and restrictions affected study implementation. The local and national consensus workshops were conducted virtually. This created difficulties for a number of people who use drugs, as it required internet access, which was often not available to them. Attempts were made to include representatives from the SANPUD network to overcome these challenges through linking with local organisations or providing data where possible. Our study is the first of its kind in South Africa. It adds to the understanding of the drug economy by quantifying the market volumes and values for cocaine, heroin, and methamphetamine using data collected by and from people who use drugs. Despite the inherent limitations of the study, the results suggest that a large drug market exists in South Africa. Considering the size of the market and the substantial revenue generated, further consideration should be given to stakeholders in the value chain. Apart from the value and volume of the market, our research provides valuable insights into the way drug markets can be researched. People who use drugs are closest to the market, have valuable insights, and are arguably best positioned to identify potential sources of data and interpret its value, relevance, and validity in situ. Thus, people who use drugs have skills, capacity, and expertise that should be included in research teams investigating drug markets. Drug markets are complex and multi-faceted. Therefore, researchers should work across fields and disciplines to develop a more comprehensive understanding of the drug market and its role and impact on communities and the national economy. Importantly, studies related to the drug market should include people who use drugs in the design and implementation of the research. Subsequent studies with more accurate input estimates, particularly around population sizes, will improve the precision of the market value estimates. This could be done through conducting more city-level population size estimations increasing rigor and geographical coverage along with research that uses emergent data to refine national estimates. Future studies that measure drug purity would provide insights into comparative drug pricing and market valuation. Additional research into the flow of money in the market and how the trade in illicit drugs impacts individuals and communities would be important to inform policy and action.

Drug market valuation The valuation of drug markets requires data on volumes and price. Methods The study employed focus group discussions FGDs , ethnographic mapping, brief interviews, and the Delphi method to gather inputs to estimate the retail drug market value in South Africa in Setting South Africa has nine provinces and is comprised of 52 districts. Procedures Activities took place between May and November Primary data collection National and local stakeholders were informed of the project. Table 1 Primary data collection activities in each city. FGDs and mapping Between 6 and 12 people, purposively sampled for diversity representing men, women, sex workers, men who have sex with men, and transgender people who use drugs , participated in a FGD at the start of fieldwork. The FGDs followed a structured guide that explored drug usage methods, frequency, volume and drug market characteristics number of users, hotspots, and drug unit cost. The mapping component included the use of stickers to plot drug use hotspots on city maps. FGDs were held in private safe spaces and were co-facilitated by the research coordinator and a person with lived experience of drug use from that city. Information was captured using a FGD guide and written notes. The FGDs each took between two and three hours. The informed consent and FGD guide were in English with translations provided by the co-facilitator. Brief interviews Brief interviews were conducted with people who use drugs in locations where people who use drugs congregate or were accessible hotspots across diverse areas in each city. Feedback from the FGDs and mapping were used to identify locations to conduct interviews and for fieldwork planning. Based on available time and resources, as many interviews and location visits were done in each city as possible. Teams convened at the beginning and end of each day to plan and reflect on the fieldwork. Working in pairs, the fieldworkers conducted up to 20 brief interviews per day lasting approximately 10—15 minutes each. The informed consent and questions were in English with translations provided by fieldworkers. Validation sessions with people who use drugs Sessions took place at the end of the fieldwork in each city. FGD participants were invited, as well as up to five people who use drugs who had insights into drug use in that city Konstant et al. The research coordinator led the sessions, which were structured and standardised. Clarity around conflicting or missing information was obtained. The research coordinator facilitated a discussion to validate the results and reach agreement on estimates. Data on the most commonly purchased form of each drug, and perceived weight of units of purchase, was obtained in each city. Considering the locations that were visited, the findings were extrapolated to the whole city. The research coordinator facilitated these sessions in English, which each took 2 to 3 hours. Population size estimation of people who use drugs This process involved a bottom up-approach, building on the city-level estimates from the fieldwork to develop district, then provincial and finally national population estimates. Retail drug market valuation The retail market value was calculated by multiplying total annual consumption by price European Monitoring Centre for Drugs and Drug Addiction Figure 1 Formula and data inputs to calculate the retail drug market value European Monitoring Centre for Drugs and Drug Addiction, Data management and analysis Procedures, tools, and training were standardised.
