In our community-based studies, we found that 23 percent of men in midlife had engaged in binge drinking during the year prior to our survey, and 14 percent of men over 65 reported an episode. The frequencies were much lower for women, but the trend remains. Binge drinking can potentially lead to a host of problems among older adults given that they metabolize alcohol more slowly and are more frail physically. Falls, driving while impaired, and confusion about the use of medications critical to their health are among the concerns. Surprisingly, 4 percent of adults aged 50 to 64 reported using marijuana during the past year.
