Black markets exist because demand exists, whether we like it or not, whether we think it's good or bad. Black markets are self regulated and that is why you see so much violence in the illegal drug market. Restricting supply drives up prices and profit and increases incentives to increase supply. This is a vicious never ending cycle.

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.
