In a modest house on a red dirt road in Ota in Ogun state, Adijat Adejumo, a 39-year-old auxiliary nurse, runs a small chemist shop. She treats common illnesses such as malaria and colds and sells painkillers, antidiarrhoeal medications and vitamins. For the past few years, she has also been selling packs of mifepristone and misoprostol, medicines included in the WHO essential medicines list to induce abortion safely.
