Parents here of 2 young addicts. They both are in recovery.
My son is half way through the Salvation Army's 6 month program. It has been a Godsend as insurance only pays for 30 days inpatient. I recognized that he he needed much longer to get his head on straight. It's free and a blessing.
My daughter did the 30 day inpatient and then AA/NA.
Read some good books for parents in our situations: Setting Boundaries for your Adult Children by Allison Bottke and Codependent No More by Beattie. They will help you set a straight path regarding your daughter.
