Thank you Icarus_Trust! I have been blogging about our life with addiction for about a year now and it helps me to research and try to understand, as well as to use it as a tool to help others and for me to try to make sense of it all. If you are interested in more posts it is : http://livingwithmydrugabusingteenager.blogspot.co.uk/
I also have a Facebook page: Trying to Survive Addiction Within the Family
It is mostly to give inspiration to others suffering in one way or another with addiction. I have shared your website on that page for I have not heard of it before and it looks very interesting.
I will also speak to my son and see how he would feel about seeking some help.
Thank you for reading and taking the time to comment, it is much appreciated.
