One of the arguments that anti-marijuana advocates make is legalizing cannabis will lead to major increases in crime and the streets of American cities will be filled with corpses if we let people smoke joints. But a new study says that's all BS.
A new study conducted by researchers in New Zealand examined crime rates at both the national level and in states after they legalized medical marijuana. They found there was virtually no change in crime rates after a state legalized medical marijuana, which indicates that cannabis legalization and crime rates are most likely unrelated.
There was one exception to this. California legalized medical marijuana in 1996, and crime rates are down around 20 percent since then. Although considering that's over two decades time, there's likely several other factors that contributed to that decline other than marijuana.
It should be noted that the study focused solely on medical marijuana legalization, and did not examine crime rates in states that legalized cannabis recreationally. But considering those states didn't see an increase of crime after legalizing it medicinally, they probably saw similar results after doing so recreationally.
Of course, anti-marijuana advocates will probably find some bogus study to prove their point on ILoveJeffSessions.com or something, so this may not be too helpful for future discussions.
