Cannabidiol (CBD) has the potential to reduce craving and anxiety in people with opioid use disorder who have been opioid‐free for at least a week, a recent study using Epidiolex, the Food and Drug Administration–approved form of the marijuana‐derived drug, has found. The study compared CBD to placebo in subjects who were exposed to drug‐related and non‐drug‐related‐cues, and measured craving and anxiety. CBD administration was short‐term (three days), but beneficial effects lasted seven days afterward. There were no effects on cognition and no adverse effects. 相似文献

Every state has its own process for regulating legal cannabis, but we have been particularly interested in Massachusetts, which has a carefully structured process for regulation of both medical (established in 2013) and the recently approved recreational dispensaries — we visited a medical dispensary recently (see ADAW, June 24). 相似文献

Last week, the United Nations Office on Drugs and Crime (UNODC) released a report revealing that the adverse health consequences of drug use are more severe and widespread than previously thought. About 35 million people globally are estimated to need treatment for drug use disorders, according to the World Drug Report 2019, released June 26. The number of opioid users is now 53 million, up 56% from previous estimates. Opioids are responsible for two‐thirds of the 585,000 drug use deaths in 2017. Across the world, 11 million people injected drugs in 2017; 1.4 million of them have HIV and 5.6 million have hepatitis C. 相似文献

Alison Howell 《International Feminist Journal of Politics》2018,20(2):117-136
This article investigates the limits of the concept of militarization and proposes an alternative concept: martial politics. It argues that the concept of militarization falsely presumes a peaceful liberal order that is encroached on by military values or institutions. Arguing instead that we must grapple with the ways in which war and politics are mutually shaped, the article proposes the concept of martial politics as a means for examining how politics is shot-through with war-like relations. It argues that stark distinctions cannot be made between war and peace, military and civilian or national and social security. This argument is made in relation to two empirical sites: the police and the university. Arguing against the notion that either the police or the university have been “militarized,” the article provides a historical analysis of the ways in which these institutions have always already been implicated in martial politics – that is, of producing White social and economic order through war-like relations with Indigenous, racialized, disabled, poor and other communities. It concludes by assessing the political and scholarly opportunities that are opened up for feminists through the rejection of the concept of militarization in favor of the concept of martial politics. 相似文献

Can Carbon Nanomaterials Improve CZTS Photovoltaic Devices? Evaluation of Performance and Impacts Using Integrated Life‐Cycle Assessment and Decision Analysis 下载免费PDF全文
In emergent photovoltaics, nanoscale materials hold promise for optimizing device characteristics; however, the related impacts remain uncertain, resulting in challenges to decisions on strategic investment in technology innovation. We integrate multi‐criteria decision analysis (MCDA) and life‐cycle assessment (LCA) results (LCA‐MCDA) as a method of incorporating values of a hypothetical federal acquisition manager into the assessment of risks and benefits of emerging photovoltaic materials. Specifically, we compare adoption of copper zinc tin sulfide (CZTS) devices with molybdenum back contacts to alternative devices employing graphite or graphene instead of molybdenum. LCA impact results are interpreted alongside benefits of substitution including cost reductions and performance improvements through application of multi‐attribute utility theory. To assess the role of uncertainty we apply Monte Carlo simulation and sensitivity analysis. We find that graphene or graphite back contacts outperform molybdenum under most scenarios and assumptions. The use of decision analysis clarifies potential advantages of adopting graphite as a back contact while emphasizing the importance of mitigating conventional impacts of graphene production processes if graphene is used in emerging CZTS devices. Our research further demonstrates that a combination of LCA and MCDA increases the usability of LCA in assessing product sustainability. In particular, this approach identifies the most influential assumptions and data gaps in the analysis and the areas in which either engineering controls or further data collection may be necessary. 相似文献

Perception of Climate Risk among Rural Farmers in Vietnam: Consistency within Households and with the Empirical Record 下载免费PDF全文
Rural farmers in Vietnamese communes perceive climate risk and potential impacts on livelihood within a complex context that may influence individual and household decisions. In a primary survey of 1,145 residents of the Thach Ha district of Ha Tinh province, we gathered data regarding perception about stability in climate, potential risks to livelihood, demographic characteristics, orientation toward risk, and interest in expanding economic activity. Temporal analysis of meteorological and economic indicator data forms an empirical basis for comparison with human perception. We ask the basic question: Are rural farmers’ perceptions of climate consistent with the historical record and reproducible within households? We find that respondents do perceive climate anomalies, with some anchoring on recent extreme events as revealed by climate observational data, and further that spouses disproportionately share perceptions relative to randomly simulated pairings. To put climate‐related risk perception in a larger context, we examine patterns across a range of risks to livelihood faced by farmers (livestock disease, pests, markets, health), using dimension reduction techniques. We find that our respondents distinguish among potential causes of low economic productivity, with substantial emphasis on climate‐related impacts. They do not express uniform concern across risks, but rather average patterns reveal common modes and distinguish climate concern. Still, among those expressing concern about climate‐related risks to livelihood we do not find an association with expressed intention to pursue changes in economic activity as a risk management response. 相似文献
