For the week ended Friday, September 25, the spot price index for a pound of cannabis dropped by $185 (9%) from $1,948 in the prior week to $1,849. Two weeks ago the price of a pound of cannabis reached a seasonal high of $2,133 per pound, and that is likely to remain the high for the year.

The volume-weighted average price in California last week was $1,580 per pound, down 12% from $1,779 in the previous week.

According to Cannabis Benchmarks, the volume-weighted average price of cannabis in Oregon rose 12% last week, from $1,682 to $1,889 a pound. In Washington prices rose 5%, from $1,758 a pound to $1,848.

In the futures market, Cannabis Benchmarks noted:

Despite a strong supply surge, rapidly increasing demand is pushing up prices in the latter months of the Forward Curve. This week’s forward deals suggest that the fall surplus will be exhausted faster than presumed just a few weeks ago. … Impending legal markets — particularly recreational ones in states such as Oregon and Alaska — are spiking interest and driving up demand. The continually inflated presence of cannabis on the national stage, new findings regarding its medical efficacy nearly weekly, and concerted marketing efforts by companies to tap multiple, new demographics that heretofore did not purchase cannabis products are working simultaneously to strain even robust supplies.
