It might seem an unlikely collaboration, but The Governor's Prevention Partnership, state Department of Consumer Protection, Connecticut State Police and Wine & Spirits Wholesalers of Connecticut (WSWC) have teamed up to combat underage drinking. The fifth annual WSWC Public Service Announcement Video Contest for Connecticut college students is underway, launched this month at the University of New Haven. Winning entries in the statewide contest - aimed at reducing underage drinking in CT - will be telecast on Connecticut broadcast and cable stations. According to material prepared by the state Department of Mental Health and Addiction Services, 32% of 12-20 year olds in Connecticut drink - which translates to about 134,000 young people. Last year's winning entry came from students at Western Connecticut State University.
