AEG AndCan Index—U.S. Demand for Cannabis Products Rises for 5th Month in a Row

  • The demand for legal cannabis products in the U.S. increased by 0.8% in September.
  • Cannabis product demand is up 7.0% over a five-month period.
  • The AndCan Index is constructed using calculations for all 50 states.


NEW YORK, NY—December 6, 2017—The demand for legal cannabis products in the United States increased by 0.8% in September 2017, according to the monthly AndCan Index, which closely monitors demand across every U.S. state. The increase marked the fifth consecutive month of growth for the AndCan Index

“This marks only the third time since the start of 2015 where we’ve observed at least five consecutive months of growth in demand for cannabis products in the U.S.,” said AEG consultant Peter J. Schwartz, who oversees the AndCan Index as well as the firm’s report on The Market for Legal Cannabis Products in the 50 United States.

AndCan Index data shows that since the start of 2015, the demand for legal cannabis products has grown by 23.1% nationwide—and since last November’s general election, when four states voted to legalize recreational use of marijuana, overall U.S. demand has increased by 9.7%.

“More than one in five Americans now live in a state with either a fully legal regime for marijuana use or has approved the implementation of such status,” said Schwartz, “This is a trend that will only grow—and we expect the effect to be an increase in demand even further in the months ahead.”

The AndCan Index was launched in June 2017. It builds from three years of comprehensive coverage of the U.S. cannabis market and assessments of demand by Anderson Economic Group; a rigorous methodology that has been presented in technical papers at two conferences of professional economists; and more than two decades of business consulting experience worldwide. Comments from other economists from these conferences, as well as additional research by Anderson Economic Group consultants, have been incorporated into the AndCan Index.

Rising higher: September marked the fifth consecutive month of growth in demand for the U.S. cannabis market.

How the AndCan Index is constructed 

The AndCan Index originates from tens of thousands of data points, including recreational and medical sales in states where cannabis products sales are legal (where available for Alaska, Colorado, Oregon, Nevada, and Washington). In addition, it includes calculations for the latent (unobserved) demand in emerging markets across the remainder of the 50 states.

Adjustments are made based on the concentration of cannabis in products that are sold both medically and recreationally—a highly-potent marijuana cigarette is indicative of greater demand for cannabis than a low-potency, cannabis-oil-infused beverage, for instance—as well as the market-share of these products, and pricing differences from state-to-state.

In those states where legal sales are not available, we estimated latent demand from survey data on marijuana usage, alcoholic beverage consumption and spending, and demographic data. Estimates are made for each state based on that state’s unique data.

Monthly data on actual purchases in states where the products are legal are the primary drivers of month-to-month variation in the AndCan Index. As states change their laws, AndCan captures the transition from latent demand to observed demand without the distortion that would be caused by incorrectly assuming that all taxable sales in newly-legalized states represent growth in consumer demand.

Historical data dates back to the start of 2015. All values are indexed to the period of the November 2016 U.S. general election. The index structure means that any value greater than 100 indicates that the market demand has increased since the baseline period of November 2016.

The same market expertise is used in the publication The Market for Legal Cannabis Products in the 50 United States—AEG’s 265 page, state-by-state analysis, now in its second edition. This publication is the leading source on the economics of the cannabis industry. It covers actual and potential market size, indicative business value, tax revenue, alcohol beverage cannibalization, legal status, and political momentum.
