I'd like to hear from other parents:
1) what do you wish you would have known sooner?
2) what would you have done different?
3) anything else you want to add
I guess my main piece of advise would be that this happens in all types of families. Loving your child and being the best parent you know how to be is not a guarantee that things won't go wrong. Be alert, be aware and be IN CHARGE. I made the mistake of thinking my son would never try serious drugs, and then when I found out he did I went into denial instead of taking serious, tough love, action.
UPDATE: Mom of Opiate Addict left me a comment reminding me that Dad and Mom recently posed this question on their blog and got a great response, so please check it out here.
