Nicotine sensitizes the mouse brain to the addictive effects of cocaine, according to recent NIDA-supported research. The results accord with the hypothesis that a person’s initial use of an addictive substance physiologically sensitizes his or her brain to the rewarding and addictive effects of other substances. If the findings carry over to people, then preventing youths from smoking might reduce their vulnerability to cocaine abuse and addiction, and cocaine-dependent individuals might ease their path to recovery by quitting smoking.
Several factors contribute to treatment professionals’ stress and burnout, including how much influence they feel they have in their organization and their caseload. Surprisingly, a NIDA-supported study found that the link between staff stress and burnout was weaker in programs with higher patient caseloads than those with lower caseloads. In addition, program administrators can help counselors reduce their stress by giving them a voice in organizational policies and procedures.
Despite the advances in treatment and prevention, roughly 50,000 new HIV infections still occur annually in the Nation. Research, in large part supported by NIDA, has produced a strategy to address this circumstance and break the epidemiological impasse: seek out HIV-infected individuals, particularly those in “hard-to-reach” groups that have minimal contact with the health care system; offer them HIV testing and treatment; and provide support to help them stay in treatment.
NIDA-funded researchers have gathered evidence that brief interventions can help adolescents move away from drug use. In a clinical trial, middle and high school students markedly reduced their substance use following two 60-minute sessions that combined motivational interviewing and cognitive behavioral therapy.
The immune system has an extraordinary ability to recognize compounds foreign to the body and eliminate them. NIDA-sponsored scientists are working to harness this ability to create vaccines that will protect individuals against the psychogenic and addictive effects of abused drugs. This animation shows one of the most promising strategies, which has already yielded partial success in producing effective vaccines against nicotine, cocaine, and other drugs.
NIDA Program Officer Dr. David Thomas speaks about the intertwined problems of pain and prescription opioid abuse, as well as the research supported by NIDA and the National Institutes of Health to address these problems.
New vaccines that aim to promote recovery from cocaine and heroin abuse showed promise in animal testing. Both vaccines induced rats’ immune system to produce high titers of antibodies that inhibit the target drug from reaching the brain. The rats’ behaviors when given access to the target drug indicated that the vaccines reduced the reinforcing effects that, in recovering people, can cause lapses to turn into relapses.
Fewer than 12 percent of adolescents who meet diagnostic criteria for prescription opioid abuse or dependence receive any treatment, according to an analysis of data from the 2005 to 2008 National Survey on Drug Use and Health. The most common reason the adolescents gave for not receiving treatment was their lack of perceived need for it.
Intensive case management was more effective in increasing treatment engagement and reducing alcohol consumption among depressed participants than among those who were not depressed, according to a followup analysis of a substance abuse treatment study involving women on welfare.
