Marijuana Usage in Washington State

In a recent posts I reviewed a research report estimating the size of the Colorado marijuana market and reported results from a survey attempting to determine the marijuana usage rate in Colorado. In this post I report results from an identical survey I ran in the State of Washington.

The Washington survey results are fairly similar to the Colorado survey.

Survey respondents believe, on average, the marijuana usage rate in Washington is 39% (versus 41% in Colorado).

Here are some additional findings for comparison.

In Colorado, females report +4% usage over males. In Washington, females report -2% usage vs males.

Both States show a negative relationship between age and usage rate.

And, both States show a negative relationship between income and usage rate.

There doesn’t seem to be a significant gap between Urban, Suburban and Rural in either State. I expected Urban survey respondents to report higher usage rates in both States.
