Federal Laws & News


Despite medical cannabis laws in 44 states, cannabis is still illegal under federal law. The federal government regulates drugs through the Controlled Substances Act, which does not recognize the difference between medical and recreational use of cannabis. But, these laws are generally applied only against persons who possess, cultivate, or distribute large quantities of cannabis.

Under federal law, cannabis is treated like every other controlled substance, such as cocaine and heroin. Under the CSA, cannabis is classified as a Schedule I drug, which means that the federal government views cannabis as highly addictive and having no medical value. Doctors may not “prescribe” cannabis for medical use under federal law, though they can “recommend” its use under the First Amendment.

As of 2016, several federal agencies have issued guidelines and other policy memorandums to manage the conflict between federal and state laws as they pertain to medical marijuana. On August 29, 2013 the Department of Justice (DOJ) issued a guidance memo to prosecutors concerning marijuana enforcement under the Controlled Substance Act (CSA) making it clear that prosecuting state legal medical marijuana cases is not a priority.   The memo included eight guidelines for prosecutors to use to determine current federal enforcement priorities.

Fortunately, most medical cannabis program’s regulations require the same guidelines ensuring that any business with a licenses are meeting these requirements as well. These guidelines include:

1. Preventing of distribution of marijuana to minors;

2. Preventing revenue from the sale of marijuana from going to criminal enterprises, gangs or cartels;

3. Preventing the diversion of marijuana from states where it is legal under to state law in some form to other states;

4. Preventing state-authorized marijuana activity from being used as a cover or a pretext to traffic other illegal drugs or other illegal activity;

5. Preventing violence or the use of firearms in cultivation and distribution of marijuana;

6. Preventing drugged driving and the exacerbation of other adverse public health consequences associated with marijuana use;

7. Preventing the growing of marijuana on public lands and the attendant public safety and environment dangers posed by marijuana production on public lands;

8. Preventing marijuana possession or use on federal property.

Conflict between State and Federal Law

States have recognized cannabis’s medical value and have either passed laws through legislature or have adopted them by initiative.

As of 2016, every federal agency except the Drug Enforcement Administration (DEA), has stopped ignoring medical cannabis. Starting with the 2009 Ogden memo and later the 2013 Cole Memo, the Department of Justice has made clear that state legal medical marijuana is not a priority. In 2010, the VA updated their policies to no longer deny veterans’ access to medical services due to their participation in a state-legal medical marijuana program. In 2014, the Treasury Department issued guidelines to facilitate banking in the marijuana industry.

Information being disseminated to the public from federal agencies has also improved, including the National Institute of Drug Abuse (NIDA) DrugFacts: Is Marijuana Medicine?, the Food and Drug Administration’s FDA and Marijuana: Questions and Answers and the National Cancer Institute’s Cannabis and Cannabinoids. Research barriers are are also beginning to fall, with the Office of National Drug Control Policy lifting the Public Health Service (PHS) review, a hurdle only cannabis researchers had to clear in 2015. Likewise, NIDA now supports letting other research centers grow research cannabis, ending the NIDA monopoly.

Important Federal Cannabis Documents

  • Cole Memo
    • allows states to continue with state adult-use cannabis regulation and stated the DOJ doesnt have the resources to start nationwide cannabis raids.
  • Rohrbacher-Farr (CJS) Amendment
    • prevents direct interference with state implementation; it should also end federal medical cannabis raids, arrests, criminal prosecutions, and civil asset forfeiture lawsuits, as well as providing current medical cannabis prisoners with a way to petition for their release.

Important Federal Cannabis Cases

  • Harborside case (2016)
    • The case was dropped at least in part the result of the Rohrabacher-Farr amendment, which prevents the DOJ from interfering with those abiding by their state medical cannabis law. Since the Harborside was dropped, it does not carry any binding legal precedent.
  • U.S. vs. McIntosh (9th Circuit) (2016)
    • The most important care involving the Rohrabacher-Farr amendment took place in the federal 9th Circuit Court. The court held that the Rohrabacher-Farr Amendment prohibits the federal prosecution of conduct that is allowed by the state’s medical cannabis law.
      The opinion remanded all of the cases that included in the appellate ruling back to the trial court. If federal prosecutors want to continue pursuing their cases against the defendants, they must prove at an evidentiary hearing that the defendant violated state law.
  • U.S. v Marin Alliance for Medical Marijuana (2015)
    • Judge Breyer from San Francisco’s federal court ruled that the prosecutions of medical cannabis defendants must be consistent with the Rohrabacher-Farr Amendment in a long-standing case with Marin Alliance for Medical Marijuana (MAMM) and its founder Lynette Shaw. Judge Breyer ruled that the Amendment “forbids the Department of Justice from enforcing this injunction against MAMM to the extent that MAMM operates in compliance with state California law.” In other words, as long as providers adhere to state law, the Amendment prevents DOJ from shutting down state-legal providers.
  • United States v. Booker (2005)
    • a Supreme Court decision, the court ruled that the federal sentencing guidelines are advisory and no longer mandatory. In addition to the sentencing guidelines, there are statutory mandatory minimum sentences, which remain in effect after United States v. Booker and primarily target offenses involving large amounts of cannabis.
