The University of Texas at Dallas (abbreviated UT Dallas)

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

Response: We examine the early deployment of mandated prescription drug monitoring program (PDMP) use (2006-2015) in the U.S., when 19 states mandated PDMP use. We find 6.37 more heroin-related deaths per million population per year—a 50.1% increase—following PDMP mandates compared to states that did not.

Twin Study Find Cannabis Legalization Linked to Increased Marijuana Use in Adults

PainRelief.com Interview with:
Stephanie Zellers
Psychology
University of Minnesota

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

Response: Many cross-sectional studies have found increases in adult cannabis consumption after the passage of recreational cannabis legalization. These studies, in large population samples across the USA, provide information about possible effects of recreational legalization in representative samples, but cannot draw causally informative conclusions. There are many confounders, like genes, pre-existing differences, and secular trends, that could be alternative explanations for any effects identified.

We utilized a longitudinal twin study to rule out many additional unmeasured confounds shared within families, like genes and aspects of the rearing environment. Importantly, we have data on identical twins before and after recreational legalization, and we have pairs where one twin lives in a recreationally legal state while their co-twin does not. By comparing these twins, we can estimate the causal impact of recreational legalization, after controlling for unmeasured confounds shared by individuals in a family.

Medical Marijuana Users Also More Likely to Also Use Tobacco

Dr. Steinberg

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

Response: As the use of cannabis for therapeutic purposes (often called ‘medical marijuana’) has grown, my colleague, Dr. Mary Bridgeman, and I became interested in exploring more about the population who use marijuana for therapeutic purposes. My research has historically focused on tobacco use and so that was one issue in particular that we focused on in this study.

We know that individuals who use cannabis, in general, are more likely to smoke, but we did not know if that was also true for those who used cannabis for therapeutic purposes.

Uninsured Pay Higher Out-of-Pocket Costs for Opioid Antidote Naloxone

PainRelief.com Interview with:
Evan D. Peet, PhD Professor
Pardee RAND Graduate School

Dr. Peet

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

Response: This study is part of a broader CDC funded project looking at access to naloxone and naloxone’s impacts on opioid-related overdose deaths. There have been increasing efforts to expand access to naloxone, with a variety of different laws being passed by states across the nation. But one part of access that has been understudied is the cost borne by patients.

High out-of-pocket costs may act as a barrier to this life-saving drug, so in this study we look at trends in out-of-pocket costs of naloxone and how they vary by payor and drug brand.

Use of Nitrous Oxide for Pain Relief During Labor and Delivery Reevaluated in Light of Greenhouse Gas Emissions Concerns

Prof. Bernd Froessler

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

Response: Nitrous oxide (N2O) is commonly used in Australia for labour analgesia. Its use in labour is potentially associated with aerosol generation. During the first wave of the COVID-19 pandemic of 2020, nitrous oxide was suspended on many birthing units to reduce the risk of transmission. This 19-day sudden disruption period at our hospital provided a ‘natural experiment’ and opportunity to re-evaluate the role and need for N2O, with the aim to determine the impact of withdrawing N2O on labour analgesia use and maternal and neonatal outcomes.

Posture and Pill Shape Affect How Quickly Pain Relief Medications Dissolve and Work

Rajat Mittal Ph.D.

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

Response: I have worked on the biomechanics and fluid dynamics associated with many different organ systems in the past including the cardiovascular system, the larynx and cerebral hemodynamics, and there is very extensive research being done on these organ systems by research groups all over the world. However, as I was looking to initiate research in some new directions, the implications of stomach biomechanics on important conditions such as diabetes, obesity, gastroparesis, malnutrition and GI infections etc. became apparent to me.

Furthermore, it was clear that bioengineering research in this arena lags other more established areas such as cardiovascular flows by at least 25 years and there seemed to be great opportunity to do impactful work. We focused on drug dissolution for our first project because it offered  “low-hanging fruit” in terms of new and impactful insights.

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

Response: This study evaluates data on illicit synthetic cannabinoid poisonings reported to the National Poison Data System (NPDS) which contains data from 55 poison centers in the US (https://aapcc.org/about/our-members). We correlated the 7600 poisonings reported between 2016 and 2019 with the reporting state’s status of cannabis legalization: restrictive, medical and permissive.

Low Back Pain: Early Physical Therapy Associated with Reduced Imaging, Invasive Procedures and ER Visits

Dr. Skolasky

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

Response: Low back pain (LBP) affects a sizeable proportion of the US population (from 1.4 to 20%), and accounts for substantial healthcare expenditures (between $12 billion and $91 billion, not accounting for indirect costs associated with loss of productivity and unemployment). Current recommendations for initial treatment of acute low back pain include physical therapy. Earlier initiation of physical therapy has been associated with less healthcare utilization and spending; however, these studies have been limited to single institutions or health systems. Research is needed to evaluate the effects of early physical therapy on healthcare use, particularly within the first 30 days after initial presentation for acute low back pain, when they are most likely to experience pain and seek care.

Higher Potency Cannabis Associated With Greater Risk of Addiction

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

cannabis marijuana weed pot

Response: Cannabis is the third most used drug globally, after alcohol and nicotine. Experimental studies show that THC, the main psychoactive component, causes intoxication, cognitive impairments, as well as symptoms of anxiety and psychosis-like experiences and these effects are dose-dependent, which means that higher potency cannabis products (products with high THC concentrations) could increase the risk of harm to cannabis users. 

Previous studies have shown that concentrations of THC in cannabis have increased over the years. In the US and Europe concentrations of THC in cannabis have more than doubled over the past 10 years. In addition, new legal markets have facilitated the appearance of cannabis products with higher potencies than earlier products, such as cannabis concentrates. We also know from previous studies that cannabis use is associated with mental health disorders and 22% of people who use cannabis are estimated to meet the criteria for cannabis use disorder (CUD) or cannabis addiction. 

International increases in cannabis potency and the availability of higher potency cannabis products makes it especially pressing to understand the association of cannabis potency with mental health outcomes.
