Cross-sectional cause of death comparisons for stimulant and opioid mortality in San Francisco, 2005-2015.
Opioids and stimulants (e.g., cocaine or methamphetamine/amphetamine [MAMP]) are major contributors to acute substance toxicity deaths. Causes of stimulant death have received little attention. We sought to characterize and compare causes of death and significant contributing conditions among persons who died from acute opioid, cocaine, or MAMP toxicity. ⋯ Stimulant compared to opioid deaths tended to involve cardiac or cerebrovascular causes of death, and cocaine deaths were more likely than MAMP deaths to involve significant contributing cardiac conditions. Mounting evidence suggests that stimulant use be considered a cardio/cerebrovascular risk factor and clinical care be adjusted to address this heightened risk.

Observational StudyFentanyl and heroin contained in seized illicit drugs and overdose-related deaths in British Columbia, Canada: An observational analysis.
Due to the alarming rise in opioid-related overdose deaths, a public health emergency was declared in British Columbia (BC). In this study, we examined the relationship between illicit fentanyl and heroin found in seized drugs and illicit overdose deaths in BC. ⋯ This research contributes to the expanding body of evidence implicating illicit fentanyl use (often combined with heroin or other substances) in overdose deaths in BC. Policy makers and healthcare providers are urged to implement drug treatment and harm reduction strategies for people at risk of overdose associated with current trends in illicit opioid use.

Randomized Controlled TrialExamining effects of medical cannabis narratives on beliefs, attitudes, and intentions related to recreational cannabis: A web-based randomized experiment.
This experimental study tests effects of exposure to video narratives about successful symptom relief with Medical Cannabis (MC) on attitudes, beliefs, and intentions related to recreational cannabis use. ⋯ These results suggest that narrative news media coverage of MC may influence public attitudes toward recreational cannabis. Because such media stories continue to be commonplace, it is important to examine potential spillover effects of this coverage on public perceptions of recreational cannabis. Cannabis prevention programs should address the role of media coverage in shaping public opinion and address the distinction between medical and recreational cannabis use.

The impact of acute and short-term methamphetamine abstinence on brain metabolites: A proton magnetic resonance spectroscopy chemical shift imaging study.
Abuse of methamphetamine (MA) is a global health concern. Previous 1H-MRS studies have found that, with methamphetamine abstinence (MAA), there are changes in n-acetyl-aspartate (NAA/Cr), myo-inositol (mI/Cr), choline (Cho/Cr and Cho/NAA), and glutamate with glutamine (Glx) metabolites. Limited studies have investigated the effect of acute MAA, and acute-to-short-term MAA on brain metabolites. ⋯ In acute MAA, there was damage to the integrity of neuronal tissue, which was enhanced with short-term MAA. From acute to short-term MAA, activation of neuroinflammatory processes are suggested. This is the first 1H-MRS study to report the development of neuroinflammation with loss of neuronal integrity in MAA.

Opioid use and stigma: The role of gender, language and precipitating events.
The stigma of drug addiction is associated with negative perceptions and can be a barrier to treatment. With the rise in opioid overdose deaths, understanding stigmatizing attitudes towards individuals who use opioids is a crucial matter. There is a lack of opioid use research on stigma and, therefore, we aimed to discern stigmatizing attitudes towards people with opioid addiction. ⋯ Our results indicated that there were higher stigmatizing attitudes overall towards a male, an individual labeled as a "drug addict" and an individual who took prescription opioids from a friend. Interaction effects also showed that a female labeled with an "opioid use disorder" and male labeled as a "drug addict" were rated with higher stigma. The findings from our study are the first to show that information about gender, precipitating events and language matter when assessing stigma and opioid use and may affect the delivery of patient care.
