The demand curve for drugs is extremely inelastic, meaning that people don’t change their drug consumption very much in response to changes in prices. Therefore, vigorous enforcement means higher prices and higher revenues for drug dealers. (via Let’s Be Blunt: It’s Time to End the Drug War - Forbes)
The more effective prohibition is at raising costs, the greater are drug industry revenues. So, more effective prohibition means that drug sellers have more money to buy guns, pay bribes, fund the dealers, and even research and develop new technologies in drug delivery (like crack cocaine). It’s hard to beat an enemy that gets stronger the more you strike against him or her.
Yesterday, April 20, was pot day. I would’ve mentioned it, but was too high :)))
