Weed Wonks Podcast: Johns Hopkins researchers on “clearing up the guesswork” on medical cannabis

December 11, 2025

In the latest episode of Weed Wonks, Jordan Wellington of Strategies 64 is joined by Johns Hopkins University researchers Dr. Cerina Dubois, Dr. Johannes Thrul, and Dr. Ryan Vandrey for an in-depth look at the “absolute dearth of medical research” on cannabis and their efforts to correct it.

The trio discuss their project, funded by the National Institute on Drug Abuse, that seeks to “clear up the guesswork” on medical cannabis through a landmark study of more than 10,000 patients. They explain why it’s important to better understand the plant from a medical and scientific standpoint, implications of their research on the issue of cannabis and driving, and why we must expand our understanding of how patients use medical cannabis. 

They also highlight the impact of having different lists of qualifying medical conditions in each medical cannabis state, the importance of using data to understand which cannabis formulations best treat which conditions, and how this can help clinical decision-making for health care providers.
