How the Night Before Thanksgiving Became One of the Heaviest Drinking Nights of the Year

OSUS warns residents about alcohol-related risks tied to the night before Thanksgiving

The night before Thanksgiving has become known for heavy drinking, crowded gathering spots and increased risky behavior among young adults returning home for the holiday. National traffic safety data consistently show sharp rises in alcohol-related crashes, emergency room visits and impaired driving incidents during Thanksgiving week, beginning with the night before the holiday. The South Carolina Department of Behavioral Health and Developmental Disabilities’ Office of Substance Use Services (OSUS), through its prevention initiative Open Conversation SC, is urging families to talk openly and make safe decisions ahead of this high-risk night.

“This night may seem like a harmless holiday tradition, but the reality is that excessive drinking contributes to more crashes, more injuries and more preventable tragedies,” said Michelle Nienhius, Manager of Prevention and Intervention Services for OSUS. “We want South Carolinians to enjoy reconnecting with friends and family, but we also want them to get home safely.”

National data show that the night before Thanksgiving, sometimes called “Blackout Wednesday,” is a high-risk night for alcohol-involved fatal crashes, especially among drivers ages 21–24. Hospitals and law enforcement agencies also see increases in alcohol-related calls over the holiday weekend, including DUIs, falls and injuries linked to binge drinking.

“For many young people, the night before Thanksgiving feels like an unofficial kickoff to the long weekend,” said Nienhius. “But excessive drinking is deadly, even on holidays. Honest conversations and simple planning can turn a risky night into a safe one.”

Open Conversation SC encourages families to use Thanksgiving week as a time to talk about alcohol use, especially with teens and college-aged adults who may feel pressure to take part in heavy drinking traditions. Discussing expectations, arranging transportation and staying connected throughout the night can significantly reduce the risk of harm. Prevention efforts also rely on simple steps like choosing a sober driver, using rideshare services and stepping in when someone has had too much to drink. Friends can make a lifesaving difference by ensuring no one drives impaired.
