Colorado's legal cannabis sales continue to smash records, mainly because of the increased interest in concentrates and edibles. Dispensary sales in April surged by 58 percent over the same period previous year, according to Boulder-based BDS Analytics.

What's more, the monthly sales of $117-million beat last December's record $101-million in sales.

"Every significant category contributed to April's robust growth," BDS Analytics, which tracks cannabis sales across the country, said in the release, adding that retail dollars and units sold rose substantially across the industry. Edibles sales saw an 83 percent increase over last April to $13-million. Sales of flower grew to $67-million, and concentrates reached $27 million - a staggering 133-percent growth.

"The rapid growth in concentrates and edibles is the continuation of a two-year trend, as consumers increasingly prefer alternative consumption methods to smoking," BDS Analytics CEO Roy Bingham told Civilized in an e-mail.

"Since all such products are branded," Bingham explains, "it marks a steady shift toward more conventionally marketed products, which now represent over 40 percent of sales, double their market share only two years ago."

With all the new offerings on the market, it's little surprise that flower sales have waned slightly: bud itself has gone from making up 71 percent of total sales in Colorado last year, to just 58 percent this year.
