As voters in five states prepare to vote on legalization, a new report shows that legal pot is having a huge impact in the Rocky Mountain State.

The Colorado cannabis industry has quickly gone from bud to full flower, as indicated by a new in-depth data analysis by the Marijuana Policy Group.

Using a new “Marijuana Impact Model” they say is the first to “accurately characterize how this industry impacts the overall state economy,” the researchers confirmed the astounding positive impact that legalization has brought upon Colorado.

Legal cannabis activities generated an output of $2.39 billion in 2015, with almost $1 billion in sales for the year. The sales represent a 42.4 percent increase from the previous year, translating into a staggering 112 metric tons of buds and 132 metric tons of “flower-equivalent” products (edibles, concentrates, etc.).Cannabis now ranks number six in terms of product sales, following closely behind cigarette sales. It beats gold mining by a large margin, and even performing arts and sports venues as well as all non-grain crop farming.

However, the real impact is seen when put in terms of “output and employment per dollar spent,” where spending in the cannabis industry outperforms all private industries in Colorado – including coal and other mining, oil and gas, casinos, business services, general manufacturing and retail trade (incl. alcohol).

Each dollar spent on retail cannabis generates $2.40 in state output, while cannabis manufacturing follows with $2.34 and cannabis cultivation comes in at a close $2.13. Combining the three, cannabis is generating far more than any other entity, including federal government spending.

Much of this has to do with the fact that the Colorado cannabis industry operates almost entirely within the state, due to continuing prohibition in other states.
