One out of every 143 U.S. patients who received a prescription for an opioid painkiller in 2008 obtained prescriptions from multiple physicians in a pattern that suggests misuse or abuse of the drugs.
Researchers found that 1 in 8 high school seniors had used a prescription opioid nonmedically, and 70 percent of these teens had compounded the attendant risk by co-ingesting an opioid with one or more other drugs. Nonmedical opioid use was significantly more prevalent among whites than among African Americans or Hispanics.
A new vaccine hindered the often-abused prescription opioids oxycodone and hydrocodone from entering the brain and suppressed one of the drugs’ signature central nervous system effects. The findings warrant continued development of the vaccine as a potential aid in the treatment of oxycodone and hydrocodone abuse and dependence.
People who use prescription opiates nonmedically are more likely to consider suicide than those who use these medications only appropriately or not at all. A recent NIDA-supported study also disclosed that the risk for suicidal thoughts remains elevated after cessation of use.
Fewer teens are using cigarettes, alcohol, and most illicit drugs, according to NIDA’s latest Monitoring the Future study. Troubling trends persist in marijuana use, however, and nonmedical prescription drug use remains a concern.
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.
Researchers report a significant advance in the search for medications that can suppress pain but avoid opioids’ abuse potential and other undesirable CNS effects. A new compound reduces mouse responses in animal models of neurogenic and chronic inflammatory (e.g., arthritic) pain. The compound, called UB937, enhances the natural pain-killing activity of the neurotransmitter anandamide, and exerts its analgesic effects entirely in peripheral tissues, without entering the brain.
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.
Describes research to develop new compounds that match or exceed the pain relief provided by opioids while avoiding their shortcomings.
Reports on scientists who pinpointed the biochemical trigger from morphine that sets off a chain reaction that inhibits an immune cell that is key in fighting viruses and cancer.
Highlights the work of investigators who discovered key ways in which morphine may accelerate the progression of AIDS in animal studies.
Reports on results from a study showing that men and women with alcohol use disorders are more likely to report nonmedical use of prescription drugs than people who don't drink at all.
Presents highlights of a study indicating that exposure to morphine during adolescence may increase sensitivity to the drug during adulthood.
Describes research investigating a naturally occurring brain chemical that shows early promise as a treatment for addiction in animal studies.
