Insights into the value of the market for cocaine, heroin and methamphetamine in South Africa

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 2020. Nationally, we estimated there to be: 400,000 people who use heroin (probability range (PR) 215,000–425,000) consuming 146.00 tonnes (PR 78.48–155.13) with a value of US$1,898.00 million (PR US$1,020.18–US$2,016.63); 350,000 people who use cocaine (PR 250,000–475,000) consuming 18.77 tonnes (PR 13.41–25.47) with a market value of US$1,219.86 million (PR 871.33–1,655.52) and 290,000 people who use methamphetamine (PR 225,000–365,000) consuming 60.19 tonnes (PR 6.58–10.68) and a market value of US$782.51 million (PR 607.12–984.88). The combined value was calculated at US$3.5 billion. 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.
