<s>[INST] How can injecting drug users reduce their risk of contracting HIV? [/INST] For injecting drug users, certain steps can be taken to reduce personal and public health risks:

Take drugs orally (change from injecting to non-injecting drug use).
Never re-use or share syringes, water or drug-preparation equipment.
Use a new syringe (obtained from a reliable source, e.g. a chemist or via a needle–syringe programme) to prepare and inject drugs each time.
When preparing drugs, use sterile water or clean water from a reliable source.
Using a fresh alcohol swab, clean the injection site prior to injection. Source: UNAIDS. Link: https://www.unaids.org/en/frequently-asked-questions-about-hiv-and-aids. Field: Infectious Disease. Disease: HIV </s>
