Article Synopsis
- The study investigates high-risk opioid use and related issues in Lithuania, noting a rise in heroin and amphetamine use since 2000.
- Research found a significant population of high-risk opioid users (HROU) and people who inject drugs (PWID) in 2015/2016, with estimates ranging from 4,854 to 12,444 HROU.
- The coverage of opioid substitution treatment (OST) and needle/syringe programs (NSP) is considerably lower than in other EU countries, highlighting the need for greater investment in these harm-reduction services.
