WEDNESDAY, Aug. 13 (HealthDay News) -- It may be possible to prevent a drug addiction relapse by disrupting the brain's attempts to retrieve drug-associated memories, according to new research.

U.K. researchers reduced drug-seeking behaviors in rats by blocking their brain's NMDA-type glutamate receptor, which is vital for learning and memory, during the recall of drug-associated memories. Researchers have known that recalling memories linked to previous drug use, such as environmental cues, can cause recovering drug addicts to relapse.

TUESDAY, Aug. 12 (HealthDay News) -- A host of new studies confirm that the effects of war linger long after the conflict ends.

The Aug. 13 issue of the Journal of the American Medical Association is a special themed issue on violence and human rights, and three studies published in that issue found that various mental health issues, such as alcohol misuse and post-traumatic stress disorder (PTSD), were more common after exposure to violent conflicts. The one bright spot was a study that found suicide rates weren't higher for returning combat veterans.

FRIDAY, Aug. 8 (HealthDay News) -- A gene variant that may influence a person's initial response to smoking and lifetime smoking habits has been identified by a team of researchers.

The finding about the variant in the CHRNA5 nicotine receptor gene may help explain how someone goes from trying their first cigarette to becoming a long-term smoker.

Previous studies have inked variations in the same genetic region to a smoker's level of nicotine dependence, to the number of cigarettes smoker per day, and to an increased risk of lung cancer.

When people think of substance abuse, they automatically think of alcohol and illegal drugs or street dugs, such as cocaine and heroin. What most people are not going to think about are the drugs that are given to people with the permission of their doctor. When people abuse a substance, it is not always something that is illegal. It can be prescription drugs that people, even teenagers, sometimes abuse. In fact, studies show that while pain medication is one of the most abused substances in North America, medications such as cough syrup are often abused by young adults.

Legislation that would subject the tobacco industry to regulation by U.S. health authorities was passed Wednesday by the House in a 326-102 vote.

Under the bill, the Food and Drug Administration would have the power to regulate tobacco products. The FDA couldn't ban tobacco or nicotine, but it could order the reduction or elimination of cancer-causing chemicals in tobacco smoke, the Associated Press reported.

THURSDAY, July 10 (HealthDay News) -- In 2006, when he was 17, Harrison Neal of Tulsa, Okla., died in his sleep after knowingly ingesting prescription drugs meant for someone else.

"We're a very typical middle-class family from Tulsa," his father, Gary Neal, said. "And Harrison was a good kid. . . . He had a 3.5 grade average, a beautiful girlfriend, tons of very good friends, and he enjoyed all the normal kid stuff. "

But Harrison Neal was also addicted to prescription drugs, a fact that was well-known to his family, who supported him in his struggle to overcome that addiction.

If we heard that someone was a workaholic 30 years ago (if we even used that term back then) I bet most of us would assume the culprit was male. I bet all of us would.

But women as workaholics is a reality that is rapidly growing in numbers.
