The more research is released, the more legalization makes sense.

Back in the 1930s, the arguments to criminalize cannabis were bizarre and openly racist. The anti-pot crusader Harry Anslinger made all sorts of over-the-top claims, such as, “Marihuana is a short cut to the insane asylum. Smoke marihuana cigarettes for a month and what was once your brain will be nothing but a storehouse of horrid specters.”

Nowadays more than 100 million Americans say they’ve smoke pot, millions use cannabis regularly to treat illnesses and it is as legal as alcohol in two U.S. states. However, it remains illegal under federal law largely due to scare tactics ingrained in our society, which date back even prior to Anslinger.

Today, pot legalization opponents try a little harder to sound reasonable, but their claims don’t do much better than Anslinger’s under scrutiny. Recent studies have picked apart the justifications for criminalizing marijuana. Here are five of the most popular arguments against cannabis legalization that are easily undermined by objective data.

1. Pot leads to crime.

If alcohol prohibition taught us anything it’s that prohibition itself leads to crime, not what is prohibited. While cannabis has shaken the psychotic Reefer Madness reputation over the years, the association between weed and crime is still alive and well in certain realms of the media, which are happy to present data without appropriate statistical caveats.

As for the studies that carefully and objectively examine their data, they find no association between cannabis and crime. A recent study in the journal PLOS One found that in states that legalized medical marijuana between 1990 and 2006 the crime rate either remained the same or decreased.
