Not on ballot

The federal government has classified marijuana as an illegal controlled substance since 1970. However, voters have had a chance to weigh in on marijuana in state law in multiple states.

In 1996, the first state legalized marijuana for medical use in state law. In 2012, the first states legalized marijuana for recreational use in state law.

As of April 2021, 36 states and Washington, D.C., had passed laws legalizing or decriminalizing medical marijuana; an additional 10 states had legalized the use of cannabis oil, one of the non-psychoactive ingredients found in marijuana, for medical purposes. Nineteen of the states that had legalized medical marijuana did so through citizen-initiated ballot measures, and the other 16 did so through legislative action.

As of June 2021, 18 states had legalized recreational marijuana. Voters had approved ballot measures to legalize the recreational use of marijuana in 13 states and Washington, D.C., as of April 2021. Thirteen of the measures were citizen initiatives, one was a legislative referral. The measure in South Dakota was overturned by a circuit court and by the state supreme court upon appeal. Six additional states—Illinois, New Mexico, New York, Vermont, Virginia, and Connecticut—legalized recreational marijuana through legislative action.

This page outlines the marijuana-related measures that had appeared on the ballot from the first marijuana-related measure in California in 1972 through 2020. To learn more about the history of marijuana laws in the United States, see this article.

Quick hits

  • The first time a marijuana legalization measure appeared on the ballot was in California in 1972, when voters rejected Proposition 19.
  • Between 1972 and 2020, voters in 21 states voted on 75 marijuana-related ballot measures. Of these measures, not all were marijuana legalization efforts; some were bans, some were related to medical marijuana, and some were related to taxing medical or recreational marijuana. Most of these ballot measures, however, were designed to move statewide marijuana laws in the direction of legalization and decriminalization.
  • The first state to legalize medical marijuana was California in 1996. As of 2018, the most recent defeat of a medical marijuana measure was in Florida in 2014.
  • South Dakota's measure was overturned by a court ruling.
  • As of 2021, Vermont (2018), Illinois (2019), New Mexico (2021), New York (2021), Virginia (2021), and Connecticut (2021) had legalized recreational marijuana through legislative bills.

As of May 2021, 36 states and Washington, D.C., had passed laws legalizing or decriminalizing medical marijuana. Additionally, 10 states had legalized the use of cannabis oil, or cannabidiol (CBD)—one of the non-psychoactive ingredients found in marijuana—for medical purposes.[2] In one state—Idaho—medical marijuana was illegal, but the use of a specific brand of FDA-approved CDB, Epidiolex, was legal.[3] Based on 2019 population estimates, 67.5 percent of Americans lived in a jurisdiction with access to medical marijuana.

Unique instances

Idaho: In 2015, the Idaho State Legislature passed a bill legalizing certain types of CBD oil that was later vetoed by Governor Butch Otter (R). In response, Otter issued an executive order allowing children with intractable epilepsy to use Epidiolex in certain circumstances. [4]

South Dakota: In 2019, the South Dakota State Legislature passed a bill amending one section of law by adding Epidiolex to its list of controlled substances. The bill also exempted CBD from the state's definition of marijuana in that section.[5] Elsewhere in state law, CBD was not exempted from the definition of marijuana. This discrepancy led to confusion that left the legal status of CBD in the state unclear for a year.[6]

After the 2019 changes, Attorney General Jason Ravnsborg (R) issued a statement, wherein he argued all forms of CBD oil, apart from Epidiolex, were illegal under state law.[7] Several state's attorneys expressed disagreement with the Attorney General's statements. Aaron McGown and Tom Wollman, state's attorneys for Minnehaha and Lincoln counties, respectively, issued a joint statement where they said the discrepancy left legality open to differing interpretations. Mark Vargo, the Pennington County state's attorney, said his office would not prosecute CBD cases based on his interpretation of the state law.[6]

On March 27, 2020, Gov. Kristi Noem (R) signed House Bill 1008 into law, which legalized industrial hemp and CBD oil in the state.[8]


Overview of marijuana-related measures

Between 1972 and 2020, voters in 21 states voted on 75 marijuana-related ballot measures. Most of these ballot measures had moved statewide marijuana laws towards legalization and decriminalization. As of March 2021, medical marijuana was legal in 35 states and Washington, D.C., while the statewide recreational use of marijuana was legal in 15 states and Washington, D.C. Of the 35 states permitting medical marijuana, 19 states had achieved legalization via statewide ballot measure, and 16 states had seen the state legislature approve medical marijuana directly without voter approval.[9]

As of April 2021, 12 states that had legalized recreational marijuana did so through statewide ballot measures. In May 2014, Congress voted to halt federal prosecutions of medical marijuana users in states that have legalized the drug’s use with a doctor’s prescription.[10]

Criminalization of marijuana via the ballot

There had been one statewide instance of voters choosing to criminalize marijuana through a ballot measure. In 1990, voters in Alaska decided to make all marijuana possession illegal. Prior to the passage of the Alaska Marijuana Criminalization Initiative, adults over 18 were legally allowed to possess up to four ounces of marijuana in their homes and up to one ounce of marijuana in public. Eight years later, Alaskans ultimately decided to decriminalize medical marijuana, and in 2014, Alaska voters to legalize recreational marijuana as well.

Public opinion regarding marijuana

Gallup, a national polling firm, first began surveying Americans about legalizing marijuana use in 1969. At that time, only 12 percent of all adults supported legalization. Since then, support for legalization has increased significantly. In 2019, a majority of American adults—66 percent—supported legalization. The table below breaks down support for legalization by age bracket.[12][13]
