Detoxification is a crucial protion of effective treatment of ADHD.  Adding more chemicals with medication maybe be helpful at times, but it is hardly a long term fix.

Regardless of your stance, conventional or alternative, detoxification needs to be a part of a comprehensive approach to something as complex as ADD/ADHD. The developing system of a child is more susceptible to adverse effects from environmental toxicity and this needs to be addressed in a comprehensive and safe manner.
