The New England ATTC Harm Reduction Coordinator, Dr. Brendan Jacka, is co-hosting the Recovery Science and Harm Reduction Reading Group meeting on April 15th, 2021 from 12:30 PM to 1:30 PM, in partnership with RICARES and the People Place and Health Collective. This discussion will focus on "Adapting Substance Use Treatment for HIV Affected Communities During COVID‑19: Comparisons Between a Sexually Transmitted Infections (STI) Clinic and a Local Community Based Organization". COVID-19 has disrupted our daily routines and may be particularly detrimental to individuals using substances, particularly people who use opioids and crystal methamphetamine. Co-occurrence of crystal methamphetamine use and new HIV infections among men who have sex with men is high, and susceptibility to COVID-19 is a growing concern.
