“Our state’s efforts to regulate the sale of marijuana are succeeding. A few years ago, the illegal trafficking of marijuana lined the pockets of criminals everywhere. Now, in our state, illegal trafficking activity is being displaced by a closely regulated marijuana industry that pays hundreds of millions of dollars in taxes. This frees up significant law enforcement resources to protect our communities in other, more pressing ways.”

                                                — Washington State Gov. Jay Inslee and Attorney General Bob Ferguson


In November 2012, Colorado and Washington State voters replaced marijuana prohibition with taxation and regulation for adults over 21. Legal sales began in 2014. The states’ economies have prospered, and opponents’ dire predictions have not materialized. Since 2014, eight additional states have legalized and regulated marijuana for adults 21 and older: Alaska, California, Illinois, Massachusetts, Maine, Michigan, Nevada, and Oregon. This document focuses on data from the first two states since their laws have been in effect the longest.

Tax Revenue and Job Creation

  • In 2018, Colorado collected more than $250 million in taxes from marijuana businesses.[1]
  • Washington generated $434 million from cannabis excise and sales taxes in 2018.[2]
  • Cities and towns have raised millions of dollars in local taxes and fees and used the funds for infrastructure projects, programs that address homelessness, and college scholarships.
  • Colorado has issued 41,812 licenses to individuals to work directly in the marijuana industry.[3] Marijuana businesses also boost the economy by retaining a wide variety of collateral services, including construction, security, legal, plumbing, and real estate.

Displacing the Illicit Market and Freeing Up Police Time

  • A report commissioned by Colorado found “a comparison of inventory tracking data and consumption estimates signals that Colorado’s preexisting illicit marijuana market for residents and visitors has been fully absorbed into the regulated market.”[4]
  • As the L.A. Times reported, “Widespread legalization in the U.S. is killing Mexico's marijuana business, and cartel leaders know it.” Seizures at U.S. ports of entry have plummeted from 2.4 million pounds of marijuana in 2013 to 861,231 pounds in 2018.”[5]
  • In a 2018 analysis, researchers found that police solved significantly more violent and property crimes after passage of legalization laws in Colorado and Washington.[6]  

Teens’ Marijuana Use and Graduation Rates

  • According to the most comprehensive study on teen marijuana use in Colorado, teen use has not risen since marijuana became legal: It dropped within the margin of error.[7] 
  • The most in-depth survey in Washington suggests either no change or modest decreases in current marijuana use for every grade surveyed — 6th, 8th, 10th, and 12th graders’.[8]
  • A 2018 study focused on youth in Washington State found, “no evidence that policy change influenced heavy-using adolescents’ rates of use nor the proposed risk factors associated with problematic use patterns.”[9]
  • The Colorado Department of Education reports that Colorado’s four-year graduation rate increased from 75.4% for the class of 2012 to 80.7% for the class of 2018.[10] The state’s 2017-2018 dropout rate was 2.2%, an all-time low. Washington’s four-year graduation rates have also increased — from 77.2% in 2012 to 80.9% in 2018.[11]

Road Safety

  • A paper published by the National Bureau of Economic Research analyzed the rates of drivers found with THC (marijuana’s primary psychoactive ingredient) in their systems after fatal car crashes from 2013 to 2016. The researchers then compared the patterns of THC-positive drivers in Colorado and Washington during that time period to those in other states. In a summary of their results, the authors wrote, “We find the synthetic control groups saw similar changes in marijuana related, alcohol-related and overall traffic fatality rates despite not legalizing recreational marijuana.”[12]

Real Estate and Quality of Life

  • In 2018, U.S. News & World Report ranked Denver, Portland, and Seattle — all of which have regulated marijuana sales for adults — in the top 10 best places to live in the nation.
  • Home prices rose fastest in the country in the only three states where marijuana was being legally sold to adults in 2015 — Colorado, Washington, and Oregon.[13]

Business, Booming Economies, and Tourism

  • In Colorado, “loss costs” — lost wages and medical expenses from on-the-job injuries — have been decreasing since 2014. 2019 saw a 16.7% decrease.[14]
  • In 2019, U.S. News & World Report ranked Colorado the best state economy in the nation, with Washington ranking third.[15]
  • An economic analysis of the legal marijuana industry in Colorado found that it generated $2.4 billion in overall economic activity in 2015.[16] (Marijuana sales increased by more than 50% since 2015 from just under $1 billion to over $1.5 billion.)
  • Colorado broke records for number of visitors and amount of tourist dollars spent for the eighth year in a row in 2017.[17] In 2017, Colorado attracted 84.7 million U.S-based travelers, plus nearly one million international visitors who collectively spent $20.9 billion and generated $1.28 billion in state and local tax revenue.
