There’s a few things- Does he have insurance? If not, have him apply for VA Medicaid. This will open up a lot of various state programs.

You can contact the Portsmouth Community Services Board, they have same day access for crisis services and should be able to point you to a community-based provider or route to substance abuse programs (if that is the presenting issue).

Depending on the level of need, I work for a mental health community based provider funded through Medicaid and might be able to point you to some more resources for the Hampton Roads area. If I can be of any assistance, feel free to DM me.
