Walk-in Substance Use Support
In order to maintain Stonewall counseling services during the COVID-19 “shelter-in-place” order, Stonewall will be offering ongoing groups and “walk-in” services remotely via Zoom. See Walk In Schedule below for details.
We provide non-shaming and sex-positive counseling and support for people interested in examining their relationship to drugs including crystal meth, cocaine, crack, GHB, ketamine, opioids and alcohol.
All substance use goals are supported and welcome. That means, whether you’re looking for safer use, managed use, reduced use, partial abstinence, or complete abstinence, there’s something for you.
The Stonewall Project counseling services are available for gay, bisexual, queer and trans men and other men who have sex with men. Safer injection and smoking supplies and support from Syringe Access Services and the Harm Reduction Center are available for everyone. Services are confidential and free of charge.
