Drug money, such as booze money during Prohibition, has corrupted countless police, Drug Enforcement Administration agents, border patrol agents, prosecutors and judges... Because illegal drugs are unregulated, their purity is unknowable -- accounting for thousands of overdose deaths and injuries... Let's stipulate that some unknown number of Americans will become addicts after legalization, who otherwise would not have. We must ask whether the terrible price we are now paying -- in police costs, international drug control efforts, border security, foregone tax revenue, overdose deaths, corruption and violence -- is worth it.
