Recreational marijuana has been on the Colorado market for over two years now, and we’re starting to get some interesting data about the preferences of its consumers.

Tradiv, an online cannabis-distribution platform, and BDS Analytics, a cannabis-focused analytics company, teamed up to release a report outlining the most popular marijuana strains in the legal Colorado market.

Marijuana comes in two distinct species, sativa and indica, and they’re thought to have different effects on your mind and body.

Many of those effects, however, are user-reported, and the science isn’t totally clear on how the particular compounds in the marijuana actually interact with your brain, as Business Insider’s Melia Robinson reported.

Generally speaking, sativa strains are considered to be energizing “head” highs, while indica strains are more subdued “body” highs, helpful for putting you to sleep.

Blue Dream, the top-selling strain, is a “pretty potent sativa,” John Manlove, the director of sales at Tradiv told Business Insider over the phone.

Consumers like it because it gives them an “energetic” high, Manlove said. But it’s not only popular because of consumers — it’s also easy to grow and cultivate.

“It’s not a fickle strain,” Manlove said. “It’s not very susceptible to mold and pests, and the common stresses on a plant.”

More importantly, it’s a high-yielding strain, so for cultivators, the economics of growing Blue Dream make sense.

The report itself is based off of point-of-sale data from a sample of Colorado cannabis retailers that represent 15% to 20% of the market. The sample was then fed through a proprietary algorithm to represent the whole market, Liz Stahura, the vice president of BDS Analytics, told Business Insider in an email.
