Ross was tempted by helping to increase supply. Maybe if we had a legal and regulated location where you could do any drugs but under the supervision of counselors we could help reduce demand and end the cycle.
I believe a church in the Netherlands did this in their basement. They provided discounted heroin that could only be used there and addicts reduced their consumption and had access to counselors.
I am not supporting what Ross did to give access to illegal drugs, I just believe because there is such demand trying to reduce supply is a losing battle where only law enforcement equipment supply companies win.
