This book presents an introduction to the design and manufacture of fibre-reinforced composites. The mechanical properties of unidirectional composites are considered in a structural design context. The use of woven and random fibres is also addressed. The accuracy of design estimates for unidirectional composites is benchmarked against test data, and the relevance of a factor of safety (FoS) is established. The importance of prototype testing is emphasised. This book illustrates how to make a fibre-reinforced composite. Wet layup, vacuum bagging and prepreg moulding are covered in detail. Some guidance on mould design and construction is also provided. Finally, an introduction to the manufacture of composite tubes is presented. Wherever possible, design and make examples are used to illustrate the content. Tutorial questions and problems are included at the end of each chapter. The reader is encouraged to use these questions and problems to assesstheir own level of understanding of the content.

This book addresses how to estimate substance use and thereby evaluate policies intended to reduce the harms caused by drugs and other substances. Wastewater analysis (WWA) can provide efficient, affordable, fine-grained and objective data on population substance use trends on a very large scale. The authors discuss the potential implications of WWA as a new method for understanding substance use in a variety of settings and ignite a discourse with policy makers, criminologists, epidemiologists and other disciplines about the need for collaboration with WWA scientists. The book also features an explanation of the costs and harms of substance use with academic literature from criminological and epidemiological sources and reports from lead agencies. Additional features include: Details on the origin of wastewater analysis in environmental science Description of analytical chemistry methods for tracing a wide variety of substances, including illicit drugs, alcohol, tobacco and other chemicals Exploration of the major empirical problems in estimating population consumption of alcohol, tobacco and drugs at the international and national level Examination of the principles of human research ethics and their application to wastewater analysisWastewater Analysis for Substance Abuse Monitoring and Policy Development is a valuable tool for analytical chemists, wastewater scientists and criminologists, as well as researchers and policy makers across disciplines who work in drug sectors.

The first edition of Addictions established itself as a valuable resource for students and professionals alike. This authoritative new edition builds on the success of the previous book, incorporating advances in research and practice over the last ten years. The book includes material on:the nature of addiction and who becomes addictedhealth consequences of alcohol and other drug dependencetheories and causes of addiction. The authors, experts in the field, also include new material on the controversy surrounding the possible positive effects of alcohol and cannabis use, the increased risk of interpersonal violence, and new research on theories of addiction. Addictions will be essential reading for students, professionals and researchers seeking state of the art information about this rapidly growing field.

Addiction is a significant health and social problem and one of the largest preventable causes of disease globally. Neuroscience promises to revolutionise our ability to treat addiction, lead to recognition of addiction as a 'real' disorder in need of medical treatment and thereby reduce stigma and discrimination. However, neuroscience raises numerous social and ethical challenges: • If addicted individuals are suffering from a brain disease that drives them to drug use, should we mandate treatment? • Does addiction impair an individual's ability to consent to research or treatment? • How will neuroscience affect social policies towards drug use? Addiction Neuroethics addresses these challenges by examining ethical implications of emerging neurobiological treatments, including: novel psychopharmacology, neurosurgery, drug vaccines to prevent relapse, and genetic screening to identify individuals who are vulnerable to addiction. Essential reading for academics, clinicians, researchers and policy-makers in the fields of addiction, mental health and public policy.

Cannabis, marijuana, pot, ganja - it goes by many names -- is by far the most widely used illegal substance, and accounts for more arrests than any other drug. Barely a week goes by without this drug appearing in the newpapers, and politicians have famously tied themselve in knots, trying to decide just how to deal with this recreational drug. While there have been many drug policy books on other substances - both legal and illegal, few have focused on this drug. Cannabis Policy: Moving beyond Stalemate is unique in providing the materials needed for deciding on policy about cannabis in its various forms. It reviews the state of knowledge on the health and psychological effects of cannabis, and its dangerousness relative to other drugs. It considers patterns and trends in use, the size and character of illicit markets, and the administration of current policies, including arrests and diversion to treatment, under the global prohibition regime. It looks at the experience of a number of countries which have tried reforming their regimes and softening prohibition, exploring the kinds of changes or penalties for use for possession: including depenalization, decriminalization, medical control, and different types of legalization. It evaluates such changes and draws on them to assess the effects on levels and patterns of use, on the market, and on adverse consequences of prohibition. For policymakers willing to look outside the box of the global prohibition regime, the book examines the options and possibilities for a country or group of countries to bring about change in, or opt out of, the global control system. Throughout, the book examines cannabis within a global frame, and provides in accessible form information which anyone considering reform will need in order to make decisions on cannabis policy (much of which is new or has not been readily available). This book will be essential for those involved in policymaking and be of interest to a wide range of readers interested in drugs and drug policy, as well as being an excellent supplementary text for university courses in criminology, policy science, social science, or public health.

The use of cannabis in the late twentieth and this century is an area of medical and moral controversy. Despite its illegality, cannabis is the most widely used drug after alcohol and tobacco among young adults in the USA, Europe and Australia. This book explores the relationship between health policy, public health and the law regarding cannabis use. It assesses the impact of illegality in drug use and relates this to policy analysis in Australia, the UK, the US and other developed societies. It evaluates debates about 'safe use' and 'harm minimisation' approaches, as well as examining the experiences of different prevention, treatment and education policies. Written by two leading drug advisors Cannabis Use and Dependence makes a valuable addition to this important field of research.
