The Guardian reports on another study showing a decrease in crime with legalization of marijuana:
The introduction of medical marijuana laws has led to a sharp reduction in violent crime in US states that border Mexico, according to new research.
According to the study, Is Legal Pot Crippling Mexican Drug Trafficking Organizations? The Effect of Medical Marijuana Laws on US Crime, when a state on the Mexican border legalised medical use of the drug, violent crime fell by 13% on average. Most of the marijuana consumed in the US originates in Mexico, where seven major cartels control the illicit drug trade.
“These laws allow local farmers to grow marijuana that can then be sold to dispensaries where it is sold legally,” said the economist Evelina Gavrilova, one of the study’s authors. “These growers are in direct competition with Mexican drug cartels that are smuggling the marijuana into the US. As a result, the cartels get much less business.”
The knock-on effect is a reduction in levels of drug-related violence. “The cartels are in competition with one another,” Gavrilova explained. “They compete for territory, but it’s also easy to steal product from the other cartels and sell it themselves, so they fight for the product. They also have to defend their territory and ensure there are no bystanders, no witnesses to the activities of the cartel.
“Whenever there is a medical marijuana law we observe that crime at the border decreases because suddenly there is a lot less smuggling and a lot less violence associated with that.”
In other words, the experience with marijuana prohibition is similar to what we experienced with alcohol prohibition.
This also shows a failure of our political system. Despite ending prohibition being both the sensible choice, and a choice favored by a large majority of Americans, there has been little pressure to change the system from either major political party. While the two parties find plenty to fight over, there is little difference over what they parties actually do on far too many issues.
