This chart reflects my understanding as of 18 October 2017, and reflects recent changes in CO, MA, NV, and WA. Comments and corrections welcomed. Oregon’s 20-percent number reflects a 17-percent state tax and universally adopted 3-percent local taxes. Otherwise local taxes are more of a patchwork, and are ignored. Colorado and Nevada have nominal 15-percent producer taxes. Colorado converts its tax to a weight base for related party or vertically integrated cases. https://newrevenue.org/2017/07/23/is-colorados-new-marijuana-tax-leaky/. Nevada converts to a weight base for all cases. https://newrevenue.org/2017/07/02/nevadas-70-cent-per-gram-tax-on-marijuana-flower/
