Drugs of Abuse, Immunity, and AIDS


Book Description

This volume is based on the program of the Second International Conference on Drugs of Abuse, Immunity and AIDS, held in Clearwater Beach, FL in June 1992. The Conference was supported in part by the University of South Florida College of MediCine with financial assistance from the National Institute on Drug Abuse. The focus of this conference was the effects of drugs of abuse on immunity. It is now widely recognized that psychoactive drugs of abuse, including marijuana, cocaine, and opiates, as well as alcohol, have marked effects in an individual, including effects on their nervous system and behavior. In the past two decades, the scope of studies concerning the effects of some drugs of abuse have also involved investigations of alterations of various physiologic parameters including effects on the immune system. and the influence of such immune alterations on normal physiological responses. In this regard, participants in this Second International Conference provided newer information concerning both basic and clinical aspects of drugs of abuse and immunity, especially immunodeficiencies. In this regard, advances have been made in recent years concerning the nature and mechanisms whereby the immune system is regulated and the possible mechanisms by which drugs of abuse influence such immune systems. In particular, the emergence of psychoneuroimmunology as a new discipline the last decade has heightened interest in the immune responses influenced by psychoactive drugs. This has resulted in interdisciplinary investigations involving both clinical and basic scientists, including microbiologists, immunologists, physiologists, psychiatrists, oncologists, psychologists, etc.

Drug Abuse Treatment: A National Study of Effectiveness




Marijuana As Medicine?


Book Description

Some people suffer from chronic, debilitating disorders for which no conventional treatment brings relief. Can marijuana ease their symptoms? Would it be breaking the law to turn to marijuana as a medication? There are few sources of objective, scientifically sound advice for people in this situation. Most books about marijuana and medicine attempt to promote the views of advocates or opponents. To fill the gap between these extremes, authors Alison Mack and Janet Joy have extracted critical findings from a recent Institute of Medicine study on this important issue, interpreting them for a general audience. Marijuana As Medicine? provides patientsâ€"as well as the people who care for themâ€"with a foundation for making decisions about their own health care. This empowering volume examines several key points, including: Whether marijuana can relieve a variety of symptoms, including pain, muscle spasticity, nausea, and appetite loss. The dangers of smoking marijuana, as well as the effects of its active chemical components on the immune system and on psychological health. The potential use of marijuana-based medications on symptoms of AIDS, cancer, multiple sclerosis, and several other specific disorders, in comparison with existing treatments. Marijuana As Medicine? introduces readers to the active compounds in marijuana. These include the principal ingredient in Marinol, a legal medication. The authors also discuss the prospects for developing other drugs derived from marijuana's active ingredients. In addition to providing an up-to-date review of the science behind the medical marijuana debate, Mack and Joy also answer common questions about the legal status of marijuana, explaining the conflict between state and federal law regarding its medical use. Intended primarily as an aid to patients and caregivers, this book objectively presents critical information so that it can be used to make responsible health care decisions. Marijuana As Medicine? will also be a valuable resource for policymakers, health care providers, patient counselors, medical faculty and studentsâ€"in short, anyone who wants to learn more about this important issue.




Preventing HIV Transmission


Book Description

This volume addresses the interface of two major national problems: the epidemic of HIV-AIDS and the widespread use of illegal injection drugs. Should communities have the option of giving drug users sterile needles or bleach for cleaning needs in order to reduce the spread of HIV? Does needle distribution worsen the drug problem, as opponents of such programs argue? Do they reduce the spread of other serious diseases, such as hepatitis? Do they result in more used needles being carelessly discarded in the community? The panel takes a critical look at the available data on needle exchange and bleach distribution programs, reaches conclusions about their efficacy, and offers concrete recommendations for public policy to reduce the spread of HIV/AIDS. The book includes current knowledge about the epidemiologies of HIV/AIDS and injection drug use; characteristics of needle exchange and bleach distribution programs and views on those programs from diverse community groups; and a discussion of laws designed to control possession of needles, their impact on needle sharing among injection drug users, and their implications for needle exchange programs.




Drugs of Abuse, Immunity, and Infections


Book Description

During the past few decades, drugs of abuse, including marijuana, cocaine, opiates, and alcohol have been studied in detail by biomedical scientists in terms of their effects on the neurophysiology and psychological responses of individuals. Research over the last few years has provided increased knowledge about possible mechanisms by which such drugs increase the likelihood of infections in humans and experimental animals. In Drugs of Abuse, Immunity, and Infections prominent investigators review important new information concerning the effects of recreational drugs on susceptibility to infection by microorganisms. The volume examines the effects of drugs such as cocaine, morphine, marijuana, and opiates on immunity in humans and animals. It covers the molecular and cellular mechanisms of drug-induced immunosuppression and describes the overall enhanced susceptibility to infection in recreational drug users. It discusses the alteration of susceptibility to the retrovirus that causes the acquired immunodeficiency syndrome (AIDS) and the consensus that drugs of abuse may serve as a possible cofactor in the progression of AIDS. Drugs of Abuse, Immunity, and Infections also includes important information concerning public health aspects of drugs of abuse and infection.




The Health Effects of Cannabis and Cannabinoids


Book Description

Significant changes have taken place in the policy landscape surrounding cannabis legalization, production, and use. During the past 20 years, 25 states and the District of Columbia have legalized cannabis and/or cannabidiol (a component of cannabis) for medical conditions or retail sales at the state level and 4 states have legalized both the medical and recreational use of cannabis. These landmark changes in policy have impacted cannabis use patterns and perceived levels of risk. However, despite this changing landscape, evidence regarding the short- and long-term health effects of cannabis use remains elusive. While a myriad of studies have examined cannabis use in all its various forms, often these research conclusions are not appropriately synthesized, translated for, or communicated to policy makers, health care providers, state health officials, or other stakeholders who have been charged with influencing and enacting policies, procedures, and laws related to cannabis use. Unlike other controlled substances such as alcohol or tobacco, no accepted standards for safe use or appropriate dose are available to help guide individuals as they make choices regarding the issues of if, when, where, and how to use cannabis safely and, in regard to therapeutic uses, effectively. Shifting public sentiment, conflicting and impeded scientific research, and legislative battles have fueled the debate about what, if any, harms or benefits can be attributed to the use of cannabis or its derivatives, and this lack of aggregated knowledge has broad public health implications. The Health Effects of Cannabis and Cannabinoids provides a comprehensive review of scientific evidence related to the health effects and potential therapeutic benefits of cannabis. This report provides a research agendaâ€"outlining gaps in current knowledge and opportunities for providing additional insight into these issuesâ€"that summarizes and prioritizes pressing research needs.




New Treatments for Addiction


Book Description

New and improved therapies to treat and protect against drug dependence and abuse are urgently needed. In the United States alone about 50 million people regularly smoke tobacco and another 5 million are addicted to other drugs. In a given year, millions of these individuals attemptâ€"with or without medical assistanceâ€"to quit using drugs, though relapse remains the norm. Furthermore, each year several million teenagers start smoking and nearly as many take illicit drugs for the first time. Research is advancing on promising new means of treating drug addiction using immunotherapies and sustained-release (depot) medications. The aim of this research is to develop medications that can block or significantly attenuate the psychoactive effects of such drugs as cocaine, nicotine, heroin, phencyclidine, and methamphetamine for weeks or months at a time. This represents a fundamentally new therapeutic approach that shows promise for treating drug addiction problems that were difficult to treat in the past. Despite their potential benefits, however, several characteristics of these new methods pose distinct behavioral, ethical, legal, and social challenges that require careful scrutiny. Such issues can be considered unique aspects of safety and efficacy that are fundamentally related to the distinct nature and properties of these new types of medications.




Drugs of Abuse, Immunity, and Immunodeficiency


Book Description

This volume is based on the program of the International Conference on Drugs of Abuse, Immunity and Immunodeficiency held in Clearwater Beach, Florida. It was sponsored by the University of South Florida College of Medicine with the support of the National Institute on Drug Abuse. During the past few decades, drugs of abuse, including marijuana, cocaine, opiates and alcohol, have been studied by biomedical scientists in terms of the systemic effects of the drugs as well as alterations in neurophysiology and the psychology. More recently, the scope of such investigations has been broadened to include alterations within the immune system, and the influence of altered immunity on physiological and psychological consequences of drug abuse. In this regard, participants in the Clearwater Beach conference provided new information concern ing both basic and clinical aspects of drugs of abuse and immunity, especially immunodeficiency. Advances have been made in recent years in understanding the nature and mechanisms regulating the immune response and the mechanisms by which drugs may influence immune responses. In particular, the emergence of psychoneuroimmunology as a new discipline has heightened interest in immune responses influenced by psychoactive drugs. This has resulted in interdisciplinary investigations involving clinical and basic scientists including microbiologists, immu nologists, physiologists, psychiatrists, oncologists and others. The recreational use of the above mentioned drugs by large numbers of individuals has aroused serious concern about the consequences of this activity.




HIV and Disability


Book Description

The Social Security Administration (SSA) uses a screening tool called the Listing of Impairments to identify claimants who are so severely impaired that they cannot work at all and thus qualify for disability benefits. In this report, the Institute of Medicine (IOM) makes several recommendations for improving SSA's capacity for determining disability benefits more accurately and quickly using the HIV Infection Listings.




Alcohol, Drugs of Abuse, and Immune Functions


Book Description

Substance abusers are an immunocompromised population, vulnerable to a wide array of new and resurgent infectious diseases - in spite of modern treatment. For example, opportunistic infections like tuberculosis are the principal cause of morbidity and mortality in HIV positive patients. Alcohol- and drug-induced disorders are wide-ranging, gaining prominence as the spectrum of emerging diseases broadens. Alcohol, Drugs of Abuse, and Immune Functions reviews the role of these immunosuppressants as cofactors in disease. It covers the basic biology and immunology of impairments to defense against infectious disease. Alcohol and drug use is consistently associated with immunosuppression, although it isn't known if it is the substance itself, a metabolite, or an indirect effect that alters disease resistance. This text explores the advances toward answering this question, examines alcohol in different settings, its relationship to important cells, and the effects it can have on vital organs such as the liver and the lungs.
