Timing of Recreational Cannabis Laws (RCLs) by Year-Quarter Among Implementing States, 2010 to 2019 States were coded as implementing an RCL in a quarter-year when it was implemented by the end of the first month of that quarter. For example, a state that implemented an RCL by January 31, 2017, was counted as implementing it in the first quarter of 2017. Implementation refers to the date on which the law went into effect, not the date on which it was passed. Credit: JAMA Health Forum (2022). DOI: 10.1001/jamahealthforum.2022.4069
