Dr. Sanjay Gupta: A Decade of “Weed”

Stephen Andrews
19 Mar 2026

In 2013, CNN’s Chief Medical Correspondent Dr. Sanjay Gupta made a rare public reversal for a prominent medical journalist: he apologized for previously dismissing cannabis as a potential medicine. After reviewing emerging research and patient cases, the neurosurgeon said earlier coverage had relied too heavily on federal drug classifications and incomplete scientific evidence. Over a decade later, his “Weed” documentary series stands as one of the most widely viewed mainstream television explorations of medical cannabis in the United States.


From the story of Charlotte Figi to recent discussions surrounding federal rescheduling, Dr. Gupta’s films chronicle how public debate around cannabis evolved during a pivotal period. Here is the complete breakdown of the documentaries that helped reshape public discussion around medical cannabis.

The “Weed” Series: A Documentary Chronology (2013–2025)

Released over more than a decade, each of the seven installments reflects a different stage in the shifting national conversation around cannabis.

Weed 1: The First Time (2013)

The first documentary marked a turning point in mainstream media coverage of medical cannabis. Gupta introduced viewers to Charlotte Figi, a young girl with Dravet Syndrome whose severe seizures were dramatically reduced after treatment with a high-CBD cannabis extract—a strain later named in her honor, Charlotte’s Web.

Beyond the individual story, the documentary helped normalize CBD for a broader American audience and contributed to what media outlets later described as a “medical refugee” movement, as families relocated to Colorado seeking access to similar treatments.

Weed 2: Cannabis Madness (2014)

The Emory University School of Medicine neurosurgery professor followed the political fallout of the first film, investigating why federal law still classified cannabis as Schedule I (no medical value) despite the evidence he had witnessed.

Weed 3: The Marijuana Revolution (2015)

His third installment explored how THC and CBD work together, expanding discussion toward whole-plant therapeutic theories such as the entourage effect. 

Weed 4: Pot vs. Pills (2018)

At the height of the opioid crisis, Gupta explored claims that cannabis could function as an “exit drug” for some patients. He interviewed patients who successfully reduced or replaced prescription opioid use with cannabis. 

Weed 5: The CBD Craze (2019)

As the 2018 Farm Bill made hemp legal, Gupta investigated the booming CBD market, warning consumers about mislabeled products while reinforcing the clinical benefits of pure cannabinoids.

Weed 6: Cannabis and the Opioid Crisis (2021)

A deeper dive into neurobiology, showing how the brain’s glutamatergic system—damaged by opioid abuse—could be influenced by cannabinoids, according to emerging research discussed in the documentary. 

Weed 7: A Senior Moment (2023–2025)

The latest installment addresses the fastest-growing demographic of users: Seniors. Gupta explores “Plants over Pills” for aging Americans dealing with chronic pain, insomnia, and the early stages of dementia.

  • 2025/26 Update: Gupta’s latest reporting tracks the US motion toward Schedule III, a shift he has advocated for since his original apology.

From “Madness” to Medicine: the Gupta Legacy

Beyond the screen, Dr. Gupta’s reporting coincided with broader scientific and legal developments.  

  • FDA Approval of Epidiolex: Gupta helped raise public awareness around pediatric epilepsy research that later culminated in the FDA approval of Epidiolex. 
  • The Schedule III Pivot: His persistent questioning of the DEA’s “lack of evidence” reached the highest levels of the Department of Justice, contributing to public and policy discussions surrounding federal rescheduling debates. 
  • Global Research: Gupta famously pointed out that US research was biased toward finding harm, highlighting how significant cannabis research was being conducted in countries overseas. 

While Dr. Gupta remains a “cautious” advocate, his work in a way mirrors the journey of the American public. Although, critics have argued that some episodes relied heavily on anecdotal patient experiences, reflecting the limited clinical evidence available at the time. 

Where to Watch the “Weed” Documentaries?

Dr. Sanjay Gupta’s “Weed” series was produced as a collection of CNN Special Reports, so availability varies over time. Episodes are periodically available through CNN’s website and apps with a TV provider login, as well as via on-demand cable libraries after broadcast premieres. Some newer installments have also appeared on Warner Bros. Discovery–owned streaming services, depending on regional licensing. Availability may differ by country and change periodically.
