%X <B>BACKGROUND: </B>Opioid analgesics are essential for managing acute and chronic pain in diseases such as cancer. Inadequate opioid access remains a major public health concern in low-income regions including Africa. This study aimed to provide updated and comprehensive data on changes in opioid consumption, specifically in Africa.<BR><B>METHODS: </B>This longitudinal study has updated and expanded upon the International Narcotics Control Board data obtained from 1999 to 2021, assessing opioid consumption trends across all African countries. The defined daily doses for statistical purposes (SDDD) was used to determine the changes in opioid consumption in Africa. In addition, we used sub-analyses of the data to delve into individual substances, income levels, cancer incidence, cancer mortality, and sub-regional cluster analysis (based on the language spoken) to identify possible disparities and inform further research and tailored solutions.<BR><B>RESULTS: </B>Our results indicate a persistently low and stagnant trend in opioid consumption between 2001-03 and 2019-21, from 73 SDDD (95% CI 69-77) to 55 SDDD (32-79). In-depth analysis revealed a morphine consumption increase from 735 SDDD in 1999 to 1115 SDDD in 2021. Moreover, opioid consumption was closely related to country-level income levels, with most of the low-income and lower-middle-income African countries reporting low opioid consumption. Notably, the escalating incidence and mortality rates associated with cancer in Africa indicated a misalignment with the trajectory of opioid use. Additionally, French-speaking African countries exhibited lower opioid usage than the rest of the continent, suggesting avenues for research into cultural, political, and social aspects.<BR><B>CONCLUSIONS: </B>In the context of global doubling in opioid consumption, Africa has shown insufficient and stagnant opioid consumption during the last 20 years. These findings underscore the need for policy reform to facilitate safe and responsible opioid access in Africa, particularly for legitimate indications such as cancer pain and palliative care.<BR><B>BACKGROUND: </B>None.<BR><B>UNASSIGNED: </B>For the French translation of the abstract see Supplementary Materials section.
