About DrinkSmart, LLC DrinkSmart, LLC is committed to enabling people to take responsibility for their actions when they are consuming alcohol. We are working with bar, club, and restaurant owners by making available to patrons state-of-the-art self-administered alcohol breath analyzers. In addition, DrinkSmart, LLC promotes that same kind of responsible action for people hosting parties and receptions where alcohol is being served, making it possible for friends and guests to be able to test themselves and make informed decisions as to the potential for driving impaired.
