I watched Oprah yesterday and there was a fellow addicted to crack and his father has written a book as well as the son..
Beautiful Boy: A Father's Heartache, An Addict Son
On the show the young man said that when he was stoned he ended up chasing the drug and family was considered but just that considered.. the drug was more important..
In AA/Al-anon etc we are taught that addiction is a disease.. and if our family had cancer or something like that there would be more forgiveness. (my interpretation of the words said and written)
I agree with therapy.. and maybe look into what addiction does to some people so you understand the why of it..
