Cognition in Adults Who Use Medical Marijuana for Chronic Pain Relief

University of Haifa, Haifa, Israel

PainRelief.com:  What is the background for this study?

Response: Due to increased media attention related to the topic of medical cannabis and increasing public demand for the treatment, physicians often find themselves in situations where patients and caregivers request medical cannabis treatment. When this demand is from older patients, there is a dearth of studies of effectiveness and risk-benefit ratio as almost no studies have examined the potential therapeutic effects and potential risks of the treatment in this specific group. One of the main implications of cannabis use that researchers have grappled with is its long-term effect on cognitive function. It is well established that cannabis use has detrimental effects on the developing brain when consumed in early life, but detrimental effects of early-life cannabis use may not translate to use in older ages. Use of cannabis in old ages may have adverse effects on cognition but some evidence also exists showing beneficial effects.

Study of Daily CBD for Pain Relief of Canine Osteoarthritis

Matthew Halpert, Ph.D., B.S
Baylor College of Medicine

PainRelief.com:  What is the background for this study?

Response: The background will actually encompass my disclosure.  A little over a year ago, Medterra was one of a couple of CBD companies that approached me about conducting some small scale studies focused on CBD and its anti-inflammatory properties.  It became very obvious, very quickly that some (most) companies were not interested in actual science or data, but rather just wanted to try and increase their CBD-fad based revenue by using my name and affiliations. Medterra proved to be very different and genuinely wanted legitimate data and science to support and direct products, innovations, stories etc.  I always warned them that the ‘data will be the data’ and they agreed to live by that….even if the data wasn’t as supportive as they may have hoped.  Being a true academic researcher, I found this to be more than acceptable and Medterra and Baylor College of Medicine entered into a Sponsored Research Agreement (SRA) in which Medterra provides product and money for research, and my lab performs the research and reports back the data.

Hemp Oil Studies for Pain Relief of Neuropathic Pain

PainRelief.com Interview with:
Karin Westlund High, PhD
Professor and Vice-Chair for Research
Department of Anesthesiology & Critical Care Medicine
University of New Mexico Health Sciences Center
Albuquerque, NM 87106

PainRelief.com: What are the main findings?

Response: Nearly 1 in 5 Americans recently reported that their level of pain interferes with their daily lives. Treatment options for persons with chronic pain are not optimal, particularly opioid therapies found to exacerbate pain or become ineffective over time in patients and in animal studies. While some have turned to marijuana to relieve pain where it has been legalized, benefits of the pain relieving cannabinols are not suitable for many given the psychotropic effects of its tetrahydrocannabinol (THC) content.

The Hemp Farming Act in 2019 effectively began legal cultivation in some states of a variety of the Cannabis plant—conventionally referred to as ‘hemp’. The primary components of hemp are the pain relieving cannabidiol (CBD) chemicals, differing from the content in their federally illegal counterparts which contain levels over 0.3% of the psychoactive THC. In  fact, it is reported that the content of CBD was bred down while THC bred up in marijuana seized in California  between 2001-2008.

Department of Anesthesiology and the Chronic Pain and Fatigue Research Center
University of Michigan

PainRelief.com:  What is the background for this study?

Response: Medical cannabis is legal in 33 states, and people can obtain medical cannabis licenses to treat a wide swath of conditions, including cancer, anxiety, irritable bowel syndrome, chronic pain, complications of Alzheimer’s disease, and nausea. Many observational surveys have found that many people use cannabis for chronic pain, but whether these surveys were representative of national trends was uncertain. To our knowledge, this was the first study that examined nationwide trends of patient-reported qualifying conditions based on medical cannabis state registries.

Many Patients Prescribed Medical Marijuana for Pain Relief, Use the Cannabis for Recreational Use

New Haven, CT 04519

PainRelief.com:  What is the background for this study?

Response: Currently, medical marijuana is legal in 33 states and the District of Columbia and recreational marijuana is legal in 10 states and the District of Columbia (although it remains a Schedule I drug at the federal level).

Chronic pain is an approved condition for medical marijuana in all states in which medical marijuana is legal. However, there is concern that a sizeable percentage of medical marijuana patients also are using their medicine recreationally.

In the current study, we found that more than half (55.5%) of medical marijuana patients also reported using their medical marijuana for recreational purposes, which is similar to rates observed in a previous study.
