In November 2012, Coloradans voted on a ballot initiative to regulate and tax marijuana like alcohol. Leading up to the election, opponents claimed that passage of the measure would cause more problems than it would solve. Voters were not fooled. They approved the initiative, marijuana became legal for adults on December 10, 2012, and licensed businesses began legally selling marijuana to adults on January 1, 2014. Since then, opponents’ dire predictions have proven to be unfounded, the state has experienced significant benefits, and polls show voters’ support for the law has not wavered.
In a February 2017 report, the Colorado Department of Public Health and Environment reported the percentage of women in Colorado who used marijuana during pregnancy is “not statistically different” from the national average. It highlighted a survey of pregnant women in 2014 that found 6% of new mothers consumed marijuana during pregnancy, whereas 13% consumed alcohol.
