According to Healio (8/3, Herpen), “rates of new-onset mental health conditions were higher in U.S. soldiers with a history of military-related traumatic brain injury” (TBI), “while increased risk for suicide was both directly and indirectly associated with TBI history.” Investigators arrived at this conclusion after having examined data on “more than 860,000 U.S. soldiers, including more than 108,000 with history of” TBI. The findings were published online July 31 in JAMA Network Open.

HealthDay (8/3, Murez) reports a rise in cannabis use and progression to cannabis use disorder among non-college young adults post-legalization, according to a study using data from the National Survey on Drug Use and Health. A statement by the study’s co-author encourages continued monitoring of “changes in prevalence of cannabis use, frequent cannabis use and cannabis use disorder among young adults while the cannabis landscape in the U.S. continues to evolve.” The “research doesn’t address why these changes are occurring,” but another co-author suggests changes in public beliefs about cannabis use and increased drug potency might be influencing the trend. The findingswere published in the American Journal of Preventive Medicine.
