More than 2½ months into the coronavirus pandemic, cannabis sales in five of the nations’ largest recreational markets are a mixed bag.

While the gains in Washington state aren’t quite as dramatic, sales in March, April and May 2020 increased by an average of 28.5% over the same months a year ago.

For context, Washington state’s adult-use cannabis market generated $1.1 billion in 2019 – up 8% over 2018 – meaning the 2020 sales growth rate so far is roughly three times last year’s rate.

In California, Colorado and Nevada, however, it’s clear that the pandemic has been a drag on each state’s adult-use cannabis market.

However, because tourism plays a larger role in these markets, it’s possible that consumption by in-state residents is increasing even while overall sales fall.

In Colorado, for example, medical marijuana sales – which consist solely of transactions involving in-state residents – eclipsed $36 million in April 2020, an increase of 31% over April 2019 and the strongest month of MMJ sales since August 2017.

Las Vegas – one of the most popular tourist destinations in the world – closed to outside visitors in mid-March. While 80% of adult-use cannabis sales in Nevada take place in Clark County, where Las Vegas is located, adult-use sales for the state in May fell by 25% compared to the same month last year.

The picture in California is less clear. The state’s nascent marijuana industry is grappling with a bevy of other challenges, including high prices, a lack of retail stores and an entrenched illicit market.
