INTRODUCTION: This research aims to estimate the relative risks of responsibility for a fatal accident linked to driving under the influence of cannabis or alcohol, the prevalence of these influences among drivers and the corresponding attributable risk ratios. A secondary goal is to estimate the same items for three other groups of illicit drugs (amphetamines, cocaine and opiates), and to compare the results to a similar study carried out in France between 2001 and 2003. METHODOLOGY: Police procedures for fatal accidents in Metropolitan France during 2011 were analyzed and 300 characteristics encoded to provide a database of 4,059 drivers...

Different factors influence the development of drug addiction in humans, including social reward experiences. In animals, experience with social rewards, such as sexual behavior, pair bonding, social and environmental enrichment, can be protective. However, loss or lack of social rewards can lead to a vulnerability to drug-seeking behavior. The effects of social reward experience on drug-seeking behavior are associated with changes in the neural pathways that control drug-related behavior. This review will provide an introduction and overview of the mesolimbic pathway and the influence of social reward experience on drug-seeking behavior in rodents...

Fentanyl is a potent opiate commonly administered during cardiac catheterization procedures in North America. The question of whether fentanyl could have adverse consequences in patients undergoing percutaneous coronary intervention (PCI) is raised by recent research demonstrating that intravenous morphine significantly delays the absorption of oral P2Y12 platelet inhibitors. The presumed mechanism is slowed gastric emptying. The single-center Platelet Aggregation with tiCagrelor Inhibition and FentanYl (PACIFY) trial randomized adults undergoing clinically-indicated elective coronary angiography to receive the procedure with or without intravenous fentanyl (NCT02683707)...

Background: Recent research has suggested that increases in mortality among middle-aged US Whites are being driven by suicides and poisonings from alcohol and drug use. Increases in these 'despair' deaths have been argued to reflect a cohort-based epidemic of pain and distress among middle-aged US Whites. Methods: We examine trends in all-cause and cause-specific mortality rates among younger and middle-aged US White men and women between 1980 and 2014, using official US mortality data...

REVIEW
David G Borenstein, Afton L Hassett, David Pisetsky
The Pain Management Task Force of the American College of Rheumatology published a report in 2010 highlighting pain management as a fundamental aspect of clinical practice, training and research. In the interim, the consideration of pain as a focus of attention of rheumatologists and rheumatology health professionals has become even more challenging than in 2010 because of the epidemic of opiate addiction and overdose death. The characterisation of categories of pain by mechanism (e.g., inflammation, joint degeneration, abnormalities of central pain processing) can help guide treatment...

Introduction: Prescription drug overdoses are the leading cause of accidental death in the United States. Alternatives to opioids for the treatment of pain are necessary to address this issue. Cannabis can be an effective treatment for pain, greatly reduces the chance of dependence, and eliminates the risk of fatal overdose compared to opioid-based medications. Medical cannabis patients report that cannabis is just as effective, if not more, than opioid-based medications for pain. Materials and Methods: The current study examined the use of cannabis as a substitute for opioid-based pain medication by collecting survey data from 2897 medical cannabis patients...

Current treatments of opioid addiction include primarily maintenance medications such as methadone. Chronic exposure to opiate and/or long-lasting maintenance treatment induce modulations of gene expression in brain and peripheral tissues. There is increasing evidence that epigenetic modifications underlie these modulations. This review summarizes published results on opioid-induced epigenetic changes in animal models and in patients. The epigenetic modifications observed with other drugs of abuse often used by opiate abusers are also outlined...

Orexin-A and -B neuropeptides are exclusively synthesized in hypothalamic neurons. These have been implicated to play critical roles in the expression of various behavioral manifestations such as feeding, arousal, wakefulness, drug dependence and tolerance. Orexin ligands activate orexin type-1 and orexin type-2 receptors each displaying a distinct selectivity and distribution profile. Orexinergic neurons innervate various brain structures among which the locus coeruleus (LC) and the lateral paragigantocellularis (LPGi) nuclei are well established as the two key mediators of opiate dependence and tolerance...

We are faced with a worldwide opiate/opioid epidemic that is devastating. According to the Centers for Disease Control and Prevention (CDC), at least 127 people, young and old, are dying every day in America due to narcotic overdose. The Food and Drug Administration (FDA) has approved Medication-Assisted Treatments (MATs) for opiate/opioids as well as alcohol and nicotine. The mechanism of action of most MATS favors either blocking of dopaminergic function or a form of Opiate Substitution Therapy (OST). These treatment options are adequate for short-term treatment of the symptoms of addiction and harm reduction but fail long-term to deal with the cause or lead to recovery...

Impulse control disorders (ICDs), such as compulsive gambling, buying, sexual, and eating behaviors, are a serious and increasingly recognized complication in Parkinson's disease (PD), occurring in up to 20% of PD patients over the course of their illness. Related behaviors include punding (stereotyped, repetitive, purposeless behaviors), dopamine dysregulation syndrome (DDS) (compulsive medication overuse), and hobbyism (e.g., compulsive internet use, artistic endeavors, and writing). These disorders have a significant impact on quality of life and function, strain interpersonal relationships, and worsen caregiver burden, and are associated with significant psychiatric comorbidity...

OBJECTIVE: Posttraumatic stress disorder (PTSD) and opioid use disorder (OUD) co-occur at high rates, and this co-occurrence is associated with a range of problems related to mental and physical health. OUD is commonly treated with opioid agonist therapies (OAT), which have been shown to be effective for reducing opiate use and related negative health consequences. Given the high comorbidity of PTSD and OUD, many individuals in OAT have PTSD and continue to experience symptoms of both disorders despite OAT treatment...

BACKGROUND: Alcohol and drug dependencies are associated with different social stigmas, and some studies suggest they might exhibit different clinical presentations. Further, the treatments for each vary considerably. Alcohol versus drug use problems were compared in terms of attachment patterns and related clinical treatment issues in two interlocking studies using converging logic and designs. METHODS: In Study 1, alcohol versus drug dependence was defined in terms of a known groups design...

The alarming trend in opiate misuse in developed countries is prompting an increasingly strident public call for action. Although many in our field have assumed that this building crisis does not really affect us or our patients, data show that the emerging demographic at highest risk for misusing opiates clearly includes patients who seek care in our practices. The goals of this Views and Reviews are to provide a clear understanding of emerging trends in opiate misuse, to review the impact of opiates on the reproductive axis, and to suggest practical recommendations aimed at both mitigating iatrogenic influences on promoting misuse and developing treatment frameworks when misuse is suspected or identified...

Integrative medicine (IM) is a model of care which uses both conventional and nonconventional therapies in a "whole person" approach to achieve optimum mental, physical, emotional, spiritual, and environmental health, and is increasingly popular among patients and providers seeking to relieve chronic or multifactorial conditions. The US Department of Defense (DoD) shows particular interest in and usage of IM for managing chronic conditions including the signature "polytrauma triad" of chronic pain, traumatic brain injury (TBI), and posttraumatic stress disorder (PTSD) among its beneficiaries in the Military Health System (MHS)...
