The possession and sale of marijuana remains illegal in 48 states -- though about a dozen more have moved to decriminalize possession to some extent.
That means people are still getting arrested and cited for marijuana possession and use every day in much of the country.
But whether or not pot-smokers get into trouble depends in large part on where they live. The below map from Addiction-Treatment.com and Fractl, using federal data from the FBI and Substance Abuse and Mental Health Services Administration (SAMHSA), compares each state according to how many marijuana arrests are made per 100,000 users:
So while, according to federal data, Illinois made 30,000 arrests per 100,000 users in 2012, Massachusetts made only 275.
Much of the differences, of course, have to do with what the law says in each of these states. In many Northeastern states, marijuana possession is a civil offense rather than a crime. But even states with similar laws have vastly different levels of enforcement.
Here are the 10 strictest and least-strict states:
A similar imbalance can be found when it comes to drunk driving arrests.
