Hey Triple7. I hope things are coming along for your brother. Today I drove my friend to a rehab clinic to check himself in. At the clinic I was told about a group called Co-Anon. It is much like AA or NA but designed to help family and friends through the tough task of dealing with a loved one who has a cocaine addiction. I thought I would post the website here for anyone that may be interested. They have groups all over the States, Canada, Sweden and the U.K.
