Medscape (1/24, Brooks) reports that research published in the Journal of Abnormal Psychology suggests that “heavy drinking may worsen symptoms of posttraumatic stress disorder (PTSD), and PTSD symptoms may contribute to heavy drinking in college students.” Investigators came to these conclusions after looking at “relationships between PTSD and heavy drinking (assessed by Web survey) in 486 students as they transitioned into college and at 11 additional time points during the following 3 years.”
