Response: Alcohol consumption and alcohol use disorder (AUD) are moderately heritable traits. To date, genome-wide association studies (GWAS) have not examined these traits in the same sample, which limits an assessment of the extent to which genetic variation is unique to one or the other or shared.
This GWAS examined a large sample (nearly 275,000 individuals) from the U.S. Veterans Affairs Million Veteran Program (MVP) for whom data on both alcohol consumption and alcohol use disorder diagnoses were available from an electronic health record. We identified 18 genetic variants that were significantly associated with either alcohol consumption, AUD, or both. Five of the variants were associated with both traits, eight with consumption only, and five with alcohol use disorder only.

Response: The current opioid epidemic continues to cause deaths and tremendous suffering in the United States, driven in large part by overuse of prescription opioids. Of special concern are new opioid prescriptions, i.e. opioids given to patients who have not used opioids before, which research tells us are an important gateway to long-term opioid use, misuse, overdoes and death. Recently, in their efforts to curb over prescribing of opioids, the CDC issued guidelines (December 2015 in draft form; March 2016 in final version) to encourage opioid prescribers to limit the use, duration and dose of opioids, particularly opioids to first-time users. Despite these, little is known about the prescribing of opioids to first-time users on a national scale, particularly among commercially insured patients.
In this study, we examined national monthly trends in the rate at which opioid therapy was started among commercially insured patients. Using administrative claims from Blue Cross Blue Shield Association commercial insurers from 2012 to 2017, we analyzed more than 86 million commercially insured patients across the United States.

MedicalResearch.com: What is the background for this study?
Response: Motivation for this study came from Co-Author, Matt Murray, who was at a speaking engagement and heard a community business leader say “we’ve got jobs, but no one is applying, could opioids be a contributing factor?” This led to a conversation back at the Boyd Center between us and Matt Murray, where we decided that if we could get data on prescription rates, we could answer this question empirically.
We started by contacting each state agency in charge of their respective prescription drug monitoring program to see if they’d be willing to share county-level data on prescription opioid rates. From this letter-writing campaign we received data from 10 states, which formed the basis for our analysis. As time went on, new data was made publicly available and we were able to expand the analysis to all 50 states.

Response: We study health-related behaviors, such as diet and the consumption of caffeine and alcohol.
Given the recent trends in legalization of cannabis for medical and even recreational purposes, we were concerned with the narrow focus of current public health efforts regarding cannabis. Although some in the field take a harm-reduction approach to substance use, too many efforts focus solely on abstinence. These programs are a legacy from the era of prohibition, and we know that there are disadvantages to such a restricted scope in public health.
For example, municipalities that eliminated or blocked accurate and effective sex education had increases in teenage pregnancy rates. There are so many public health-related aspects of cannabis, beyond risks and adverse effects, which need to be addressed by systematic scientific research. Because of the legal history of cannabis, there is little integration with the mainstream health care system.
The focus of the current study was investigating how medical cannabis users perceived

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Drinking alcohol is a risk factor for sustained smoking. In a sample of daily cigarette smokers receiving treatment for alcohol use disorder, we examined if reductions in drinking corresponded with reductions in nicotine metabolism as indexed by the nicotine metabolite ratio. The nicotine metabolite ratio is important because it is associated with smoking level and lapses. We found that for men, alcohol use and the nicotine metabolite ratio reduced significantly; however, for women, neither drinking nor nicotine metabolite ratio changed.
