The International Network of People who Use Drugs (INPUD) and the Global Network of Sex Work Projects (NSWP) have written a briefing paper focussing on the experiences, views, needs, and rights of sex workers who use drugs. The Briefing Paper discusses existing research and writing, and also includes case studies from sex worker-led and drug user-led organisations on the perspectives and experiences of sex workers who use drugs, and on how best to meet the needs of this community.
