The figures released Tuesday represent sales through the end of 2018.
According to the Colorado Department of Revenue, more than $1.54 billion of marijuana for medical or adult use was sold during 2018.
That is the highest one-year total for sales figures since 2014, but the pace of growth has slowed over time. In 2018, sales increased about 2.5 percent compared with 2017.
The state collected $266.5 million in taxes on marijuana products and other industry fees in 2018. That’s up from 2017, when the state collected $247 million.
Colorado voters in 2012 approved a constitutional amendment broadly permitting the sale and use of marijuana for adults. Sales began in 2014.
