Observational Analysis of the Influence of Medical Marijuana Use on Quality of Life in Patients.

Abstract

Introduction: A significant gap exists in the understanding and utilization of medical marijuana and its effects on a patient's quality of life. This is largely attributed to Cannabis' sp. Schedule 1 classification, which has impeded the scientific investigation of its effects on the endocannabinoid system (ECS) and quality of life. Additionally, conflicting results from previous studies highlight the need for more research to provide guidance to both patients and clinicians regarding the therapeutic potential of medical marijuana.

Methods: Patients over 18 years of age who were members of the Pennsylvania Medical Marijuana Program (PAMMP) were recruited from regulated Pennsylvania medical marijuana dispensaries. Eligible patients were enrolled through informed consent, following a study design that received approval from the LECOM Institutional Review Board (IRB). Over 90 days, participants were remotely administered an electronic survey every 30 days to collect medical marijuana use patterns and assess changes in quality of life.

Results: Of the 103 participants who completed the study, significant improvements were observed in physical and social functioning, emotional well-being, and energy levels within the first 30 days. Participants reported significant decreases in emotional limitations, fatigue, and pain levels. Notably, participants who used inhaled or vaped products (defined as vape cartridges and concentrates) were younger and exhibited a significantly higher increase in emotional well-being scores compared to those who used flower products (defined as dry leaf only). Participants who consumed medical marijuana for opioid use demonstrated significantly higher THC consumption compared to those seeking treatment for anxiety, chronic pain, or inflammatory bowel disease (IBD). Improvements in the first 30 days also remained constant for the remainder of the study.

Discussion: This study contributed valuable insights into the effects of medical marijuana on quality of life and highlighted potential benefits associated with its use. Moreover, ongoing research aims to assess the observed sustained improvements beyond 90 days, investigating potential long-term trends. While further research is needed to explore the underlying mechanisms of action and long-term effects of medical marijuana, clinicians and patients can gain a better understanding of medical marijuana's therapeutic potential, enabling more informed decisions regarding its use in clinical settings.
