Fine just don't ask us to pick up your medical tab.
Do you think the tab for prosecuting the drug war is less than the potential medical tab if drugs were legal? If so you have a big surprise coming.
You need to do some basic research on the cost of arresting, prosecuting and confining Americans for drug offenses. Look up the cost of police activity, the court costs and, above all, the cost of confinement. Because as it is our per capita prison census is much greater than that of China, Russia and North Korea.
We have more than two million Americans in our prisons, more than half of whom are in for drug offenses and the average cost of confinement is around $45k per inmate, per year. Add to that the residual cost of ruined lives because of unnecessary criminal records. Ex-convicts are virtually unemployable and become a burden on society in one way or another.
Even if everyone who used legalized drugs ended up in an emergency room, which is about a 99% exaggerated hypothesis, the cost would be considerably less than waging the war on drugs. Considerably less.
