The Swiss solution to the opioid crisis. Legalize. Give pure heroin to the addict who must self administer on site so he/she can be monitored. Then they leave. PLUS give support for improving the addict's life, determine and fix reasons life is shitty which led to addiction in first place. As their lives improve, the addiction levels drop....so it's not just chemical...it's situational/context/quality of life.
You need your nausea/addiction; it will tell us what's wrong w/ you.
