Looking for help for my son on heroin

My 38 yr old Son has been an addict since 2007. He’s been seriously hardcore the last ten years. We had to sever ourselves legally. If he shows up, he gets a sandwich sitting outside while the police are on their way.
He’s in jail 1/2 of each year for the typical addict mischievous activities. He’s given a script of Suboxone and sent on his way. I’ve talked with social workers, LE, parole officers, public defenders and prosecutors. All Say it’s a broken system. For years I have heard this.
There is NO HOPE for him or us survivors. This is right up there with the death of our sweet 8 year old grandson. Actually, with Alex it was final. With our Son it is not hope but fear today will be the overdose day and we get that call. But then every day just gets repeated.

I am so sorry you have to see your son go through this throwing a God given gift...Life away. Man I been there. I am now married to my soulmate and have a great life. There is hope but I understand you get burned out and expect the worse. I wish there was more I could do to help. All I can do is pray for him. Blessings to you and your family.
