The UNODC Assessment of Trafficking in Medical Products in the Sahel brought to light a terrible situation of substandard and falsified medicines in the area. 

While there are no reliable estimates of the overall quantities of medical products that are trafficked in different ways and forms in the Sahel countries, studies point to a percentage of substandard and falsified medicines in the medical market of between 19 and 50 per cent. Some 40 per cent of the substandard and falsified medical products reported in the Sahel countries between 2013 and 2021 was discovered in the regulated supply chain.
