    Problematic Use of Alcohol
       National Institute of Alcohol Abuse and
        Alcoholism recommends no more than:
           Women - 3/occasion or 7/week
           Men - 4/occasion or 14/week
           Elderly - 1/occasion or 7/week

       Problematic – harm, but does not meet
        criteria for ABUSE

        Chronic alcohol leads to increase brain-to-
         plasma cocaine ratio

     issue
    When used simultaneously form cocaethylene -
     may increase toxicity
