The concept of a substance acting as a prodrug for an intended drug is not new and has been known and utilized with particular benefits within medicine for efficacy and patient safety. Prodrugs of psychoactive substances are also not particularly new but this has also extended to considerations of prodrugs of new psychoactive substances (NPS). The continuing evolution of NPS has been a constant forensic challenge. In some countries, this constant evolution has led to the introduction of various alternative methods of drug control. Whether for this reason or in the pursuit of user experimentation, prodrugs of NPS have been discussed, developed, and exploited, posing some distinct forensic challenges. This is especially the case within toxicological analysis of biological fluids and for some substances, also forensic chemical analysis, through inherent instability of the prodrug or metabolism in the body. Particular examples of NPS prodrugs include 1-propanoyl-LSD, 1-butanoyl-LSD, 1-acetyl-LSD, and 2C-B-AN. This is in addition to associated substances and medicines that may be used for an intended pharmacological effect. Various prodrugs for stimulant and hallucinogenic substances in particular have appeared in the literature and have been discussed within drug user forums and made available for purchase online. Presently, drug monitoring data from national and international systems indicate that prodrugs are not widely available or problematic. Nevertheless, it is important that there is sufficient awareness of the prodrug concept and potential impact and associated forensic implications, not just for chemical analysis but also for toxicological considerations when a substance has been used.  相似文献

ABSTRACT

In this interview Marxist feminist theorist Silvia Federici discusses the following: the relationships between accumulation and reproduction; biotechnology; the recent resurgence of social reproduction theory as exemplified by work in Endnotes and Lies; the mystification of gendered labour; the disciplining of productive bodies; the sites and technologies of primitive accumulation in the present; and the reproduction of feminism and other social movements in the twenty-first century.  相似文献

Our article analyzes whether the federal government may constitutionally supplant a traditional system of common-law trials before state judges and juries with new federal institutions designed by statute for compensating victims of medical injuries. Specifically, this article examines the federal constitutional issues raised by various proposals to replace traditional medical malpractice litigation in state courts with a federal system of administrative "health courts." In doing so, we address the following constitutional issues: 1. Is there federal authority to preempt state law (the commerce clause and spending clause issues)? 2. May jurisdiction be created in non-article 3 tribunals, and may claims be decided without trial by jury (the separation of powers and Seventh Amendment issues)? 3. Would pilot programs that require some claims to be pursued in a federal administrative forum while other claimants are left to pursue traditional state tort law remedies be constitutional (the equal protection issue)? The article concludes that a federal compensation system through administrative health courts should be constitutional provided the statute is appropriately drafted and that appropriate factual findings are made concerning the benefits to patients and the public as well as to doctors and their insurers.  相似文献

A Social Learning Theory Model of Marital Violence   总被引:1,自引:0,他引:1  
A social learning theory model of minor and severe marital violence offending and victimization among males and females was tested. Results support social learning as an important perspective in marital violence. However, males and females are impacted differently by their experiences with violence in childhood and adolescence. Prior experiences with violence have a more dramatic impact in the lives of females than males, both during adolescence and adulthood.  相似文献

The history of crime prevention and control efforts in the United States has demonstrated little progressive improvement in our ability to deter crime. The major obstacles to implementing effective interventions and policies have been a weak scientific knowledge base about how to prevent crime, the research community's inability to effectively disseminate what is known about the causes of crime and to translate this knowledge into operational programs and policies, and a resistance on the part of practitioners and policy makers to evaluate programs and policies and to use this information in the development of new programs and policies. In the last decade, there have been major advances in our understanding about the causes of crime and we have now demonstrated the effectiveness of selected prevention programs. But there is little evidence that this scientific knowledge is informing current practice or policy. Problems in the dissemination of this information and the resistance to utilizing it remain. These problems are discussed and suggestions are made for addressing them. Our knowledge base remains modest, but it is now sufficient to inform policy and practice. The research community must work to do a better job of disseminating this information and overcoming the resistance to utilizing it before we will be successful in implementing effective crime prevention programs and policies. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

After eight years of litigation, on 21 June 2000 three hemophiliacs infected with HIV finally won a judgment against the Canadian Red Cross Society and the federal government. An Ontario trial court ruled the Red Cross and the government were negligent for having delayed the implementation of heat treatment for blood products, which resulted in the plaintiffs' infections. Since starting their lawsuits in 1992, two of the three plaintiffs died of AIDS before the trial judgment. But the damage awards were criticized by the plaintiffs' lawyer.  相似文献

On 7 June 2000, the BC Supreme Court rejected an attempt by the Vancouver Rape Relief Society to prevent the provincial human rights commission from hearing a complaint that it had discriminated against a transgendered woman. Kimberly Nixon filed a complaint with the BC Human Rights Commission in August 1995, alleging that the Vancouver Rape Relief Society had refused to allow her to work as a volunteer counselor because she had not been biologically female at birth.  相似文献
