If your parent's drinking has caused problems for you , then you may be a child of an alcoholic. You may be a kid or an adult. They are just like children of alcoholics, but the substance of abuse is another drug - marijuana, prescription pills, cocaine, heroin, whatever.
People refer to children of substance abusers as COSAs.
The Children of Alcoholics Foundation is a national non-profit that provides a range of educational materials and services to help professionals, children and adults break the intergenerational cycle of parental substance abuse.
