Taking a global snapshot Why harm reduction must focus on the public health challenge. BECOMING IMMERSED in an international harm reduction conference is quite an intense experience, but that\u2019s what we did last month at IHRA\u2019s event in Barcelona. It was the first time DDN had been to this annual event, and the first time we had been invited to produce daily magazines covering it. We decided to make the most of the opportunity by sharing some of the insights to harm reduction revealed by delegates from different countries, in this issue of the magazine. Harm reduction so often becomes one half of an over-familiar polarised debate in the UK, but looking at the reasoning behind basic measures to reduce the spread of HIV and hepatitis C is a stark reminder of the public health challenge at the heart of organisations such as IHRA. It was also an eye-opener to the different barriers to accessing treatment services posed by different cultures. Harm reduction would be a different (and very remote) concept to the drug using women in Ukraine (page 15), compared to the new International Sex Worker Harm Reduction Caucus that brought their stand and their banners to the conference to demonstrate that being loud and proud is essential to fighting the disease and discrimination that can so dangerously accompany stigma. We\u2019ve a lively letters page this fortnight (page 6), thanks to last issue\u2019s cover story \u2018Different roads\u2019. It\u2019s divided our readers and provoked some strong comments on treatment philosophy which I hope will continue. The varied backgrounds and experiences of our correspondents are enriching the debate. There\u2019s also another fan for Bri, whom I\u2019d like to thank for sharing his story (page 19). We got to know Bri at our service user involvement conference in January; he decided he would write his story in the hope of inspiring at least somebody else to keep going when the going gets tough. It\u2019s not easy to share your lowest moments, but judging by some of the feedback he\u2019s had, it\u2019s been worth the painful memories.
