Here's the scenario: You have a person who is drinking, drugging, pill-taking, smoking or -- fill in the blank -- in your life. The person is someone you care about and you clearly see that this compulsive or addictive behavior is hurting the person and affecting others -- including you. Speak to the person when he or she is not intoxicated. In as calm a voice as you can manage, mention your concern. Speak about the person's health and the way that you are affected by the person's behavior. You can also say, "I love you and want you to be healthy and enjoy life." Educate yourself about substance abuse and addiction. It is a brain illness, in which the brain has been taught to crave the mood-changing substance, despite the person's conscious wish to stop its use. Books, publications, online resources and community groups like Focus will help you learn more. Allow learning from natural consequences and permit the person to face the reality of his or her use. If health, legal, occupational or other problems result due to use of mood-altering chemicals, that person should take responsibility for these matters. This may mean paying fines, getting repairs for the OWI-damaged car, spending savings for an attorney or even going to jail.
