cc88,
When my sister was in active addiction, my parents, especially my dad, refused to believe she was using drugs. He thought she had a mental condition from hitting her head. She did hit her head hard on concrete but she was high at the time. I printed out all kinds of stuff for my Dad showing him the signs of a drug addict especially to her DOC. He still refused to see it. I totally backed off from that subject with my parents. It took my sister's lawyer (that they were paying for), looking my parents in the eye and telling them that my sister had a drug problem and what she was abusing before they got the message. I could have talked to them till I was blue in the face and for some reason, they just would not see. I don't know what it was but it took someone outside of the family unit to show them the light.
