Twenty-four states and the District of Columbia have legalized recreational marijuana so far, representing a major shift in drug policy. But the legalization movement has slowed, and in several states, activists are mounting campaigns to make recreational THC products illegal once again, including in Maine and Arizona. In November, Massachusetts voters will decide on whether to repeal the legalization measure approved in 2016. Ohio recently narrowed the cannabis legalization law passed in 2023.
One of the main concerns cited by anti-weed activists is that legalization has led to a spike in traffic accidents because more people are driving while high. But the body of research they point to has actually failed to show that marijuana legalization has increased traffic accidents or deaths.
