Non-prescription pharmacy syringes sales to people who inject drugs (PWID) in Khartoum, Sudan: policy, practice, and perceptions.

People who inject drugs (PWID) are at high risk of contracting blood-borne infections. Many developed countries started a needle exchange program to provide PWID with sterile syringes. In Sudan, healthcare professionals are exposed to legal liability if they cooperate with people who use drugs; therefore, the accessibility to sterile syringes without prescription depends heavily on pharmacists' knowledge and attitude toward PWID.
