The harvest is in, and ounces of 10%-THC cannabis are selling for$200 at commercial retail outlets in Washington. (Figure roughly 70 joints to the ounce, and at least 3 stoned hours per joint, so the cost of intoxication is roughly $1 per hour.) That price is fully competitive  with both the illicit market and the medical market.

This was utterly predictable, as I know because my RAND colleagues predicted it. So much for the argument that Washington’s taxes were too high.

What is also predictable is that prices will continue to drop, both in Washington State and in Colorado, unless the authorities start to limit production volume. $200/oz. would be a fairly reasonable price target; anything much lower than that risks a big increase in heavy use and underage use. (Of course there’s no way to keep the stuff from leaking from adults, who are allowed to purchase, to minors, who aren’t.)

Falling prices are also bad news for all the folks who thought they were going to get rich selling a newly legal product at the old, illegal prices. No such luck.
