The Medical Cannabis Research Center launched the following studies on cannabis use:

A Registry Study of Medical Cannabis Patients in Pennsylvania

This patient registry study will recruit medical cannabis patients from 17 dispensaries owned and operated by Verano.

The study will recruit up to 1,200 patients across all 17 sites. Participants will complete a baseline quantitative interview, a quantitative follow-up interview every 90 days, and a subsample will complete a qualitative interview.

The patient registry study has four specific aims:

  1. Describe the socio-demographic characteristics of patients enrolled in the medical cannabis program at ZenLeaf dispensaries
  2. Describe the medical histories of medical cannabis patients enrolled at ZenLeaf dispensaries, including the specific qualifying condition(s) for medical cannabis
  3. Describe the cannabis-using practices of medical cannabis patients enrolled at Zen Leaf dispensaries, including cannabis strains, forms, and modes of administration as well as other drug use
  4. Describe the effects of medical cannabis use on serious medical conditions, e.g., pain, opioid dependence, and related symptoms overtime among medical cannabis patients enrolled at ZenLeaf dispensaries

This study began enrollment in June 2021.

Controlled Use of Cannabis Study

The study is a continuation of R01 funding from NIDA stemming from the R01 study titled “Medical Marijuana, Emerging Adults, and Community: Connecting Health and Policy,” which started in 2013.

The long-term goal of the new study is to advance the scientific understanding of safer and controlled use of cannabis in policy environments where access to cannabis and potent products is high or increasing. The study will utilize two ongoing longitudinal cohorts of cannabis users comprised of 23-37-year-old adults in California and Pennsylvania – and employ ecological momentary assessment (EMA), quantitative surveys, and qualitative interviews.

The controlled use of cannabis study has three specific aims:

  • Develop and test a new scale assessing the rules of controlled cannabis use to be utilized during the subsequent EMA study
  • Determine daily cannabis use practices and psychosocial functioning among controlled and uncontrolled users in contrasting policy environments using EMA and a baseline survey (n=400)
  • Identify longitudinal patterns of daily cannabis use practices and psychosocial functioning among controlled and uncontrolled users using EMA and surveys from two time points (n=400), and qualitative interviews (n=100)

The study will begin recruitment in 2025 and will run through 2029.

Clinical Core

The Clinical Research Core provides the personnel and administrative support to conduct clinical trials and other clinical research activities related to medical cannabis.

It leverages Drexel’s clinical expertise and the availability of patients with qualifying conditions for medical cannabis such as, but not limited to, HIV, neuropathies, and PTSD.

Pilot Studies

The Pilot Studies arm of research is open to Drexel University faculty or postdoctoral researchers interested in studying new areas of cannabis research that are lacking preclinical and public health data. The MCRC funds between 2-3 new year-long studies that are aligned with the center’s mission on an annual basis.
