A new report has confirmed that Alaska’s marijuana tax revenue fell short two months in a row. The dip started in November 2017 and continued downward through December 2017.

According to KTVA, Alaska generated nearly $784,000 in marijuana taxes for the month of December, which is almost $100,000 less than November’s numbers.

Both months brought in less money than October, which raked in $920,000 and was the state’s most successful month for marijuana tax revenue since marijuana businesses opened in 2016.

Alaska’s marijuana tax revenue is the result of tax payments made when marijuana is sold or moved from a cultivation facility to a retail store or manufacturing facility.

Dustin Heintzelman, the state’s tax auditor, has not speculated as to the possible causes of the two-month dip, but has noted that early reports suggest that marijuana taxes collected in January will generate nearly $1 million in marijuana tax revenue.
