Marijuana rescheduling letter reveals: Cannabis less harmful than other substances

Marijuana Rescheduling

Unredacted version of previously “heavily redacted” letter prompting calls for marijuana rescheduling.

In a recent development that could reshape the landscape of cannabis regulation and taxation in the United States, the Biden administration released an unredacted letter from the Department of Health and Human Services (HHS) to the Drug Enforcement Administration (DEA). Dated August 29, 2023, the letter recommends the marijuana rescheduling from Schedule I to Schedule III of the Controlled Substances Act (CSA). This move is based on a thorough assessment of scientific evidence regarding the effects of marijuana on human health and behavior.

Scientific Basis for Marijuana Rescheduling:

The Controlled Substances Act categorizes drugs into different schedules, with Schedule I reserved for substances deemed to have no currently accepted medical use and a high potential for abuse. In contrast, Schedule III includes drugs with accepted medical uses and a moderate or low potential for abuse. The HHS letter argues that marijuana aligns more closely with Schedule III criteria, citing the Food and Drug Administration’s (FDA) comprehensive evaluation of preclinical, clinical, and epidemiological data.

The letter further emphasizes the consensus among leading public health authorities, including the National Institute on Drug Abuse (NIDA), supporting the idea that marijuana poses lower risks to public health compared to substances classified differently under the CSA. By comparing marijuana to drugs such as heroin, oxycodone, and cocaine, as well as alcohol, the HHS asserts that marijuana’s risks are comparatively lower, considering indicators like emergency department visits, hospitalizations, unintentional exposures, and overdose deaths.

Acknowledging Medical Value:

Crucially, the HHS letter recognizes the medical value of marijuana, echoing information from U.S. states that have legalized cannabis for medical purposes. It highlights marijuana’s therapeutic benefits for conditions like chronic pain, nausea, epilepsy, and multiple sclerosis. The acknowledgment underscores the need for further research to explore its potential applications for other diseases and disorders.

Origins of the Marijuana Rescheduling Recommendation:

Initiated by a petition from the Marijuana Policy Project (MPP) in 2019, the HHS letter is a response to calls for the DEA to begin the process of rescheduling marijuana under the CSA. The MPP argued that the Schedule I classification was arbitrary, irrational, and inconsistent with scientific evidence and public opinion. Furthermore, the petition contended that maintaining marijuana’s Schedule I status impeded research, harmed patients, and violated human rights.

Accessing Information through Legal Channels:

The release of the HHS letter was facilitated by attorney Matt Zorn, who filed a federal lawsuit against the DEA and HHS in 2023. Zorn aimed to compel the agencies to comply with a Freedom of Information Act (FOIA) request for documents related to the marijuana rescheduling petition, including an unredacted version of the letter, which was “heavily redacted” when it was initially released. After the lawsuit was settled, Zorn obtained 252 pages of agency communications and made them accessible to the public online. This legal effort was crucial in obtaining transparency, as federal officials had previously not responded to FOIA requests from media outlets.

Implications for the Cannabis Industry:

The HHS letter’s release has substantial implications for the U.S. cannabis industry, which anticipates federal reform to alleviate the tax burden and legal obstacles faced by marijuana businesses and consumers. Should the DEA accept the HHS recommendation and initiate the marijuana rescheduling process, the industry could experience less stringent regulations and more favorable tax treatment.

Of course, it’s wise to keep in mind that marijuana rescheduling wouldn’t automatically signal the end of federal prohibition. Federal law would still classify marijuana as illegal unless Congress passes legislation to legalize it at the national level. This distinction highlights the nuanced journey that marijuana rescheduling could set in motion, potentially paving the way for broader cannabis reform.
