WORCESTER, MA — It’s either a coincidence or a long, elaborate practical joke being played by cannabis-enjoyers across the Northeast: In 2019, recreational cannabis sales in Massachusetts totaled $420 million, according to the Cannabis Control Commission.

The first recreational cannabis stores opened in Massachusetts on Nov. 20, 2018, two years after voters in Massachusetts approved recreational marijuana. If you stretch back to that date, gross cannabis sales are at $437 million.

There are under 40 recreational cannabis stores open across Massachusetts as of Dec. 30, and that $420 million figure is in line compared to other states with recreational marijuana.

Colorado’s cannabis sales totaled $303 million in 2014, the first year stores were open there — although that figure does not include medical marijuana sales. By 2019, the Colorado industry was humming along with close to $1.5 billion in sales. In Washington state, sales totaled about $260 million in the first fiscal year between July 2014 and June 2015, but reached $1 billion by fiscal year 2016.

Nevada sold about $529 million in the first fiscal year of recreational sales between July 2017 to June 2018, according to state figures. Sales in California’s first year topped $3 billion, although that’s considered to be the largest recreational marijuana market on Earth.
