Researchers find that the relationship between prairie vole couples suffers when the male has access to alcohol, but his female partner doesn't -- similar to what has been observed in human couples. The researchers also found changes in a specific brain region in the male voles. The results could help researchers find strategies to overcome the negative effects of alcohol on human relationships.
Work underway in a laboratory at the University of Delaware suggest certain drugs can prevent and reduce changes to the brain caused by mistreatment at an early age.
Researchers conducted a critical review of existing literature to determine whether social media big data can be used to understand communication and behavioral patterns related to prescription drug abuse. Their study found that with proper research methods and attention to privacy and ethical issues, social media big data can reveal important information concerning drug abuse, such as user-reported side effects, drug cravings, emotional states, and risky behaviors.
Opioid pain relievers can be extremely effective in relieving pain, but can carry a high risk of addiction and ultimately overdose when breathing is suppressed and stops. Scientists have discovered a way to separate these two effects -- pain relief and breathing -- opening a window of opportunity to make effective pain medications without the risk of respiratory failure. The research, published today in Cell, was funded by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health.
A new study shows as many as one in 20 children were still receiving codeine to treat pain after tonsil and adenoid surgery, two years after federal regulators warned doctors that prescribing the opioid to kids after the routine surgeries could be fatal.
A new study published by the scientific journal Addiction has found that a concentrated 2mg intranasal naloxone spray delivers naloxone as effectively, over the critical first 15 minutes, as the standard 0.4mg intramuscular (IM) naloxone injection. The 2mg spray also maintains blood levels of naloxone more than twice as high as the 0.4mg IM levels for two hours after administration. It should therefore be highly effective in reversing opioid overdose.
Head injury, which often damages brain regions overlapping with those involved in addictive behaviors, does not worsen drinking behavior in people with heavy alcohol use, according to a new study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. The study also found that combining head injury with heavy alcohol use did not further alter the structure or function of the brain.
The court-ordered publication of 'corrective statements' by major US tobacco companies later this month should serve as a reminder that tobacco addiction remains a major health problem in the country and that Big Tobacco has a long history of marketing practices aimed at hooking a new generation on a lethal product, according to an editorial published online in the Annals of the American Thoracic Society.
A new Tel Aviv University study suggests that parents who smoke mistakenly rely on their own physical senses to gauge the presence of tobacco smoke in the air.
Pregnant women with opioid use disorder (OUD) are more likely to receive evidence-based treatment with an 'opioid agonist' -- usually methadone -- in states where those medications are covered by Medicaid, reports a study in the December issue of Medical Care, published by Wolters Kluwer.
