With San Bernardino hosting its first-ever extracts-only Cannabis Cup, a new holiday dedicated exclusively to concentrates, and lower barriers to entry for first-timers, cannabis extracts are more popular and potent than ever - a trend that's being borne out in both Washington state and Colorado.

According to new data collected by the Marijuana Business Daily, 175 concentrate product lines are currently available in Washington - up from just 59 product lines at this time last year.

Retailer point-of-sale information gathered by Headset indicates and average of 10 new concentrate lines are hitting the market each month. Concentrates now account for 8.3 percent of Washington's total sales of cannabis products, up from 5.1 percent in June of last year.

In Colorado, retail sales also ballooned by 125 percent in the first quarter of this year over the same period in 2015.

The reason for this growth is fairly obvious: people enjoying both the higher THC content of dabs, hash, and oil, and that concentrates can also be used in vape pens. It's a powerful combination. If the numbers are any indication, these products won't be declining in popularity anytime soon. Check out the chart from the MBD below, or read the full analysis here.
