Breaking News: Prohibition doesn't work, has unintended consequences

What happens when a state bans cigarettes in prisons? If you guessed, "A black market evolves, with skyrocketing prices, smuggling, and corruption", then you guessed well. Although that should be no surprise, as it's the same damn thing that happens any time anything people want is banned, whether it's cigarettes, drugs, alcohol, or anything. You can't eliminate vice with legislation, you can only make it more expensive and dangerous. I wonder when our stupid government is going to figure out that 90-year-old lesson?
