NEW CannMed Coffee Talk, we discuss The National Cannabis Study!
Dr. Ryan Vandrey is a professor of Psychiatry and Behavioral Sciences at John’s Hopkins. Dr. Johannes Thrul is an Associate Professor at John’s Hopkins. #shorts #cannabisbenefits #cannabisheals
They both work for the Cannabis Health & Research Initiative, which is a collaboration between two organizations with years of experience in medicinal cannabis research: @JohnsHopkins University and @RealmofCaringvideos. Simply put, CHRI is a platform of data collection and dissemination focused on the health outcomes of medicinal cannabis at the patient level, and they have created a number of valuable resources to help cannabis medicine researchers, including:
⦿ A data repository that contains de-identified data collected through CHRI
⦿ Research Library that contains more than 3000 published scientific articles related to the health effects of cannabis
⦿ A set of validated questionnaires that clinicians can use when speaking to patients about cannabis
⦿ And more!
The CHRI is also currently recruiting participants for their National Cannabis Study, which is a collection of firsthand experiences with medicinal cannabis among individuals with various health conditions. Specifically, they are looking for participants who plan to use cannabis but have not yet started cannabis use. So if that’s you or someone you know, we highly suggest you consider participating in the study because the research has the potential to impact best practices in healthcare and the cannabis industry.
During our conversation, Ryan and Johannes shared more details about the CHRI and the National Cannabis Study, and I think you will agree that their mission aligns perfectly with the CannMed Community.

![What Are Non-Glandular Trichomes? - Zamir Punja, PhD
Dr. Zamir Punja is a Professor of Plant Biotechnology at Simon Fraser University in Canada. His research interests include the etiology and management of plant diseases and the applications of plant biotechnology for disease management. Since 2018, his work has focused on cannabis, identifying and describing a range of previously unreported pathogens affecting the crop and evaluating various methods for disease management.
Zamir is CannMed regular, having presented at 5 previous events. His presentations are always a highlight of the event because they often feature stunning electron microscope images showing plant structures and pathogens up close. In fact, his CannMed 22 presentation about glandular trichomes has gotten more than 300,000 views on our YouTube page, making it the most viewed CannMed presentation.
Zamir will again present at CannMed 26, this time about non-glandular trichomes in a presentation titled Non-glandular trichomes in cannabis plants can secrete salts”.
During our conversation, we discuss:
- Non-glandular trichomes: What they are and what they do.
- How leaf spots, initially mistaken for disease, led to the finding that cannabis secrete excess fertilizer salts through these trichomes.
- Theories on why the plant would develop the ability to actively excrete excess salts.
- Practical guidance for cultivators on how to distinguish overfertilization from disease.
- Future research directions — comparing salt-tolerant vs. non-tolerant strains under varying salinity levels and exploring whether this mechanism explains cannabiss resilience in drought-prone, high-salt environments.
