The precarious intersection of the COVID-19 national health emergency and the concurrent epidemic of drug overdose deaths is outlined in the Annals of Internal Medicine this week by Dr. Nora D. Volkow, director of the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health.

This study demonstrated that functional connectivity among a large number of brain regions predicts patients’ chances of achieving abstinence in treatment for cocaine use disorder.
|
Newly released Monitoring the Future (MTF) survey data on drug use in college-age adults ages 19-22 shows an increase in marijuana use in the past five years, including vaping with marijuana, as well as a significant increase in nicotine vaping.
|
This study showed that rats will forgo heroin and methamphetamine in favor of spending time with another rat. It also highlights the importance of incorporating voluntary choice between drugs and social rewards in drug addiction research.

Las mujeres informan que sienten una euforia más intensa que los hombres al consumir cocaína y se vuelven adictas más rápidamente a esta droga. Hay estudios que han demostrado que la hormona femenina estradiol contribuye a estas diferencias, pero no cómo lo hace. Una nueva investigación, que contó con el apoyo del NIDA, ofrece una posible respuesta.
