The impact of Covid-19 on people under opioid substitution treatment.

Given the aggravation on the general population's quality of life due to covid-19 and the vulnerability of People Who Use Drugs (PWUD) to acute stress, the aim of the current study was to better comprehend the impact of covid-19 on quality of life and mental health of PWUD as well as their drug use patterns. Another study had been conducted prior to the covid-19 outbreak, which assessed quality of life, indicative PTSD symptoms, and drug use patterns of people who were attending an Opioid Substitution Treatment (OST), in Athens, Greece. As a continuation of the aforementioned study, the same variables were assessed in May and June 2020, after the first lockdown measures.
