 As far as the US federal government is concerned, cannabis remains a Schedule I drug under the Controlled Substances Act of 1970. Nonetheless, some states, which will include the District of Columbia (DC) if its statehood pushes through, have legalized marijuana for recreational, medical, or both purposes. Other states are more stringent, with limited medical cannabis laws allowing only cannabidiol (CBD) products with little to no tetrahydrocannabinol (THC), which causes the psychoactive high.

The winds of public opinion and policy reform seem to be blowing toward marijuana legalization. It's hard to ignore the tax revenue from the marijuana industry, which can generate $17.5 billion in tax revenue by 2030. Plus, the medicinal value of marijuana, particularly CBD, maybe the only hope for patients with severe medical conditions. These reasons may have motivated 30 out of the 50 states to have a marijuana law. Not just legalization is at work here; the move toward decriminalization is also evident.

By the end of this post, you will have counted the states where marijuana is legal in the US. You'll also be reading up on the laws in every state, whether it legalizes cannabis or not, and pending bills that can upend current federal laws on marijuana. The guide also examines the impact of legalization, public opinion, and prospects that can affect your life and career.

Where is Marijuana decriminalized

Where Is Marijuana Decriminalized?

In the context of marijuana, decriminalization refers to eliminating or reducing criminal penalties for the personal use and possession of the substance. By decriminalizing marijuana, possessing small amounts of marijuana becomes a civil infraction or slides one notch lower in the penalty scale.

Decriminalization differs from legalization, which has more to do with allowing medical, recreational, or both uses of marijuana, such that penalties imposed on them are lifted or abolished. State cannabis laws can vary and specify what constitutes legal use, possession, purchase, cultivation, sale, and more of cannabis, so it's critical to read the statutory provisions. It's also plausible for a state to decriminalize marijuana but not to have laws that explicitly allow adult use or that the decriminalization applies to local units.

According to the National Conference of State Legislatures (NCSL), the following jurisdictions in the U.S. have decriminalized small amounts of marijuana:

  1. Alaska
  2. California
  3. Colorado
  4. Connecticut
  5. Delaware
  6. Hawaii (decriminalization became effective on January 11, 2020)
  7. Illinois
  8. Maine
  9. Maryland
  10. Massachusetts
  11. Minnesota
  12. Mississippi
  13. Missouri
  14. Nebraska
  15. Nevada
  16. New Hampshire
  17. New Mexico
  18. New York
  19. North Carolina
  20. North Dakota
  21. Ohio
  22. Oregon
  23. Rhode Island
  24. Vermont
  25. Washington
  26. District of Columbia

Alaska, California, Colorado, Illinois (legalization effective on January 1, 2020), Maine, Massachusetts, Nevada, Oregon, Vermont, Washington, and the District of Columbia have laws permitting recreational use of marijuana.

What Are State Marijuana Laws?

The interactive map lays out US jurisdictions that have medical-marijuana and recreational-marijuana laws. Despite not enacting laws on the legalization of medical cannabis, certain states have "limited" marijuana laws for therapeutic purposes.

What Is the Impact of Marijuana Legalization?

If you were to draw a rough timeline of cannabis laws in the US based on the section above, it would look like this:

Rough timeline of Cannabis laws

Many variables are involved in the legalization of marijuana, so further research is required to measure its impact on the youth, the overall economy, and more. We look at numbers and findings with sample case studies collected so far. States that implement medical-marijuana programs have to thresh out issues, such as establishing a patient registry, dispensing, and licensing. These MMPs can take years before they become fully operational.


Taxing legal marijuana sales has been one of the motivations for legalization on a state level.

MarketWatch relates that Colorado made $270 million in tax revenues from legal pot sales in 2018, or $45 million it collected from alcohol tax. The article notes that California and Oregon missed their targeted projections for the same year.

Crime and Violence

A 2017 paper published in The Economic Journal in 2019 reveals decreased violent crimes in states or counties near the Mexican border because of medical marijuana laws (MMLs). The study notes 12 out of 16 states with MMLs as of 2012 allow for home cultivation. Ten of the 16 states have or qualify for dispensaries supplied by local marijuana farmers. The latter reduces the revenues of Mexican drug trafficking organizations (DTOs) and their "investment in violent activity.

Some will argue that legalization does not equate to reducing crime. This piece from The Hill relates an uptick in homicide rates in jurisdictions that legalize marijuana.

For example, Denver recorded a homicide rate of 67 percent in 2018 from 36 percent in 2013. Seattle peaked at 31 cases in 2018 from 19 points in 2013. Meanwhile, DC saw 160 homicide cases in 2018, compared to 116 patients a year before.


A study from The American Economic Review notes that the legalization of marijuana will remove the stigma of illegality with increased access to the drug. Does this "destigmatization" apply to employment in states with medical and recreational marijuana laws?

The NCSL notes that employers in states with marijuana laws are given discretion on drug testing and decision-making based on the drug test results. However, a state can have a law or language that protects medical or recreational cannabis users from discrimination or declined employment, as in the case of Nevada. 

What Is the Cole Memorandum?

Its critical guidance on the enforcement of marijuana was issued by US deputy attorney general James M. Cole in August 2013 during the Obama administration. The 2013 memorandum recognized state ballot initiatives that legalized the use and possession of marijuana in small amounts and regulated its production, purchase, and sale.

In the memo, the Department of Justice directed US attorneys and law enforcement to focus on the federal government's critical priorities, such as preventing the distribution of marijuana to minors. It left states and local law enforcement agencies to enforce narcotics laws and prosecute marijuana-related conduct individually.

The Cole Memo was widely seen as the federal government's way of being hands-off on states with marijuana laws. The expectation is that states will have "strong and effective regulatory and enforcement systems that will address the threat those state laws could pose to public safety, public health, and other law enforcement interests."

Rescission of Cole Memo

In January 2018, US attorney general Jeff Sessions rescinded the Cole Memo during the Trump administration. The memo took a jab at previous guidance that, according to Sessions, "undermines the rule of law and the ability of our local, state, tribal, and federal law enforcement partners to carry out the mission."

The 2018 memo emphasized the return of the rule of law, directing US attorneys to prosecute marijuana activities based on the laws of the US Congress and well-established principles.

For many, the rescission of the Cole Memo is a step back to the limbo of cannabis's legal status. Certain US representatives did respond to the reversal by introducing the Sensible Enforcement of Cannabis Act of 2019. This prevents the attorney general from prosecuting activities related to the medicinal or recreational use of marijuana or conducts that state law authorizes.

Rohrabacher-Blumenauer Amendment

The Rohrabacher-Blumenauer Amendment is hailed as the most significant legislation on the heels of the Cole Memo. The continued renewal of the amendment means that federal funds won't be used to enforce federal law in states that legalize medical marijuana.

A bit on the name: the amendment was previously known as Hinchey-Rohrabacher, after Representatives Maurice Hinchey and Dana Rohrabacher. When Representative Sam Farr took over with Rohrabacher, the amendment became Rohrabacher-Farr. With Representative Farr's retirement, Representative Earl Blumenauer took over his place, and the amendment bears the current names of the sponsors.

The amendment has been included in the annual appropriations bill passed by Congress since 2014. In June 2019, the House of Representatives voted in favor of the amendment that protects both recreational marijuana and medical marijuana programs from the DOJ's interference. However, the Senate Appropriations Committee did not take up the expanded amendment but opted to go with the amendment enacted in 2014 and pertained to state medical-cannabis laws.

Marijuana at a federal level

Is Marijuana Legal at the Federal Level?

The short answer is no. Marihuana, cannabis, or marijuana, defined in the Controlled Substances Act (CSA), is a controlled substance classified as a Schedule I and marihuana extract. 

According to the US Drug Enforcement Administration (DEA) Diversion Control Division, Schedule I controlled substances have these attributes:

Substances in this schedule have no currently accepted medical use in the United States, a lack of accepted safety for use under medical supervision, and a high potential for abuse.

The CSA, Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970, schedules substances that form the basis for federal regulation and control. Drugs listed under Schedule I and II face the strictest laws the DEA will enforce. A sense can be removed or reclassified subject to a petition.  

Notably, interested parties have called for removing cannabis from Schedule I. This is in light of states' adoption of medical marijuana laws recognizing the plant's medicinal value. Public policy research group Cato Institute proposed ending the drug war and legalizing drugs, saving the government $41.3 billion in annual enforcement expenditures.

What's Next for the Legalization of Marijuana?

(Note: states in the process of legalizing marijuana and pending proposals on the federal level )

On the State Level

According to this report, six states are on track to legalize recreational marijuana in their jurisdictions:

  • Arizona
  • Arkansas
  • Florida
  • Missouri
  • New Jersey
  • South Dakota

There can be more surprises with 2020, an election year. Nonprofit organization National Organization for the Reform of Marijuana Laws (NORML) keeps track of pending legislation for the legalization and decriminalization of marijuana. 

On the Federal Level

Here are marijuana-related proposals that are pending before Congress:

  • The Secure and Fair Enforcement Banking Act of 2019 (SAFE Banking Act of 2019) aims for legitimate cannabis-related businesses and service providers to have access to financial services. Introduced in March 2019, the bill also intends to protect institutions that will provide financial services.
  • The Compassionate Access, Research Expansion, and Respect States Act (CARERS Act) aims to amend federal law so states can make their medical marijuana policies. It's also the intention of the bipartisan bill introduced in January 2019 to permit doctors with the Department of Veterans Affairs to prescribe medical marijuana to veterans with severe or chronic conditions.
  • Regulate Marijuana Like Alcohol Act, which was introduced in January 2019, wishes to decriminalize marijuana such that it will be removed from all schedules under the CSA and its products be subject to regulation like alcohol.
  • The Marijuana Opportunity Reinvestment and Expungement Act (MORE Act), introduced in May 2019, echoes the Regulate Marijuana like Alcohol. The bill proposes the decriminalization of marijuana and the amendment of relevant laws to reflect this change. It also calls for the Health and Human Services to research the impact of marijuana.
  • The Marijuana Revenue and Regulation Act, introduced in February 2019, seeks to remove marijuana from the list of controlled substances and establish procedures for taxing and regulating marijuana.

Where Does the Public Stand on Marijuana?

Americans on marijuana legalization

What Can You Do?

The numbers and survey results shared above point to a shift toward legalizing marijuana, a movement that is sweeping the US as we speak.

You are fortunate if you live in a jurisdiction that permits access to cannabis for medical or recreational use. If not, you may have to be more proactive by participating in measures that ease restrictions on the substance at your state or federal level. You may also write to your lawmakers about your beliefs on the matter.

Indeed, the conflict between state laws and federal laws on marijuana makes it a challenge for employers to adopt drug-testing policies that comply with the rules. It's all the more reason not to rest on your laurels, as the existence of marijuana laws does not necessarily exempt you from a pre-employment drug test for marijuana.

Accordingly, here are resources for passing a workplace drug test with flying colors:
