The National Institute on Drug Abuse (NIDA) is a United States federal-government research institute whose mission is to "lead the Nation in bringing the power of science to bear on drug abuse and addiction."〔(【引用サイトリンク】title=About NIDA )〕 ==History== NIDA's roots can be traced back to 1935, when a research facility (named the Addiction Research Center in 1948) was established in Lexington, Kentucky as part of a USPHS hospital. The Drug Abuse Warning Network (DAWN) and National Household Survey on Drug Abuse (NHSDA) were created in 1972. In 1974 NIDA was established as part of the Alcohol, Drug Abuse, and Mental Health Administration and given authority over the DAWN and NHSDA programs. The Monitoring the Future Survey, which surveys high school seniors, was initiated in 1975; in 1991, it was expanded to include 8th and 10th graders. In October 1992, NIDA became part of the National Institutes of Health, United States Department of Health and Human Services. At that time, responsibility for the DAWN and NHSDA programs were transferred to the Substance Abuse and Mental Health Services Administration (SAMHSA). NIDA is organized into divisions and offices, each of which is involved with programs of drug abuse research. , Nora Volkow, MD, is the director of NIDA. According to NIH: The physical/psychological addiction dichotomy is reflected in the Controlled Substances Act's criteria for drug scheduling. Placement in Schedule III, for instance, requires a finding that "abuse of the drug or other substance may lead to moderate or low physical dependence or high psychological dependence." The view espoused by former NIDA director Alan I. Leshner, which places more emphasis on the "compulsive, uncontrollable" aspect of addictive drug use than on physical withdrawal symptoms, explains NIDA's differing treatment of morphine and cannabis. Morphine is physically addictive, and users of heroin and other opiate-derived drugs become physically and psychologically dependent on the high from the opiates, which drives them to seek the drug and perform acts they might not normally engage in (like exchanging drugs for sex acts or sharing needles with another user) . In contrast, marijuana is not physically addictive, though some users do become psychologically dependent on the drug. Jon Gettman and other supporters of removal of cannabis from Schedule I of the Controlled Substances Act have questioned the legality of basing scheduling decisions on such considerations rather than on physical addiction and physical harm; Gettman stated, "If the federal government wants to keep marijuana in schedule 1, or if they believe that placing marijuana in schedule 2 is a viable policy, then we're going to cross-examine under oath and penalty of perjury every HHS official and scientist who claims that marijuana use is as dangerous as the use of cocaine or heroin."〔() 〕 NIDA's viewpoint is supported by the fact that the CSA lists not only physical addictiveness but also "history and current pattern of abuse" and "scope, duration, and significance of abuse" among the factors to be considered in drug scheduling. Indeed, cannabis' retention in Schedule I has been partly due to findings in these areas by FDA, SAMHSA, and NIDA. The January 17, 2001 document ''Basis for the Recommendation for Maintaining Marijuana in Schedule I of the Controlled Substances Act'' specifically cites SAMHSA's National Household Survey on Drug Abuse, NIDA's Monitoring the Future survey, SAMHSA's Drug Abuse Warning Network, and NIDA's Community Epidemiology Work Group data. NIDA has supported many treatments for drug addiction. NIDA-supported studies led to the use of nicotine patches and gums for nicotine addiction treatment. NIDA scientists also developed LAAM, which is used for heroin addiction treatment. Other treatments that were the subject of NIDA research include naltrexone and buprenorphine. NIDA states, "By conservative estimates, every $1 spent on drug addiction saves society $4 to $7 in criminal justice and health care costs",〔()〕 which points to the need for spending funds on effective prevention and treatment programs based on evidence, rather than criminal sanctions that do not impact drug use. NIDA has also conducted research into diseases associated with drug use, such as AIDS and Hepatitis. NIDA views drug treatment as a means of modifying risky behavior such as unprotected sex and sharing needles. NIDA has also funded studies dealing with harm reduction. A NIDA-supported study on pregnant drug users noted, "professionals in research and treatment must learn to settle for less because insisting on total abstinence may exacerbate the problem." Interestingly, this study was conducted by Marsha Rosenbaum of the Lindesmith Center, an organization that has been critical of federal drug policies. In the 1990s, NIDA funded research by John W. Huffman that was focused on making a drug to target endocannabinoid receptors in the body; this resulted in the discovery of a variety of substances that are now being sold as Spice, K2, etc. In 2006, NIDA received an annual budget of $1.01 billion.〔(【引用サイトリンク】title=Home Page )〕 The U.S. government says NIDA funds more than 85 percent of the world's research about the health aspects of drug abuse and addiction. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「National Institute on Drug Abuse」の詳細全文を読む スポンサード リンク
