Poverty, Stress a Factor in Overdose Deaths

Drug-related deaths have grown to be a major US public health problem over the past two decades. Between 2006 and 2015 there were more than 515,000 deaths from drug overdoses and other drug-related causes. The economic, social, and emotional tolls of these deaths are substantial, but some parts of the US are bearing heavier burdens than others. Evidence from the first national study of county-level differences suggests that addressing economic and social conditions will be key to reversing the rising tide of drug deaths, reports the American Journal of Preventive Medicine.

Drug-Use Can Hamper Moral Judgment

Regular cocaine and methamphetamine users can have difficulty choosing between right and wrong, perhaps because the specific parts of their brains used for moral processing and evaluating emotions are damaged by their prolonged drug habits. This is according to a study among prison inmates by Samantha Fede and Dr. Kent Kiehl's laboratory at the University of New Mexico and the nonprofit Mind Research Network. The findings of the study, which was funded by the National Institute on Drug Abuse, are published in Springer's journal Psychopharmacology.

Substance Use Reduces Educational Achievement

Although various kinds of substance use are associated with reduced educational attainment, these associations have been mixed and may also be partially due to risk factors such as socioeconomic disadvantages.

Chronic Cocaine Use Hastens Aging of Brain

Child Abuse: Malicious Use of Pharmaceuticals

Child abuse is a serious problem that affects nearly one million children a year in the United States alone. The American Academy of Pediatrics and the US Department of Health and Human Services classify child abuse into four categories including neglect, physical abuse, sexual abuse, and emotional abuse. None of these categories, however, clearly includes the abusive use of drugs on children. A study published in the Journal of Pediatrics investigates the malicious use of pharmaceuticals and attempts to shed light on this under-recognized problem.
