Parina Subba Limbu first tried drugs as a teenager. Expelled from nine schools, she eventually ran away from home. After a decade of escalating addiction, and many disastrous love affairs with other addicts, Parina finally got help to get clean, and now runs Dristi Nepal, a charity she founded to care for drug-addicted women in Kathmandu, a group she says who are harshly judged by her society.

Melinda Ferguson, who grew up in Apartheid-era South Africa, started stealing her mother's brandy aged 10, and was soon experimenting with drugs. In 1993 she tried heroin, which led to a downward spiral that saw her losing her kids, and selling her body for the next hit. Melinda's journey to recovery began in 1999, and has since published two addiction memoirs, Smacked and Crashed.
