After many years publishing information for drug users, and text books for drug workers, the development of a sterile citric sachet to reduce the risks involved in peparing heroin and crack cocaine for injection was Exchange Supplies first 'proper' product. As well as providing sterile citric acid, produced to pharmaceutical industry standards, we also supply supporting materials, including a DVD explaining how citric acid (and vitC) work in the solution to dissolve heroin.
