Thank you for waiting. I've contemplated on your grandson's situation.
I'm so sorry to hear about his condition. I can imagine how worried, sad
and anxious you must have felt about his situation.
He has been using drugs for a few years, though he went to a rehab for one year when he was 17. He is still addicted to using drugs.
You stated he has some medical condition such as hearing disabilities and a blindness disease.
Perhaps, he may have psychiatric and neurological condition prior to his drug use. Many people with drug problems have mood disorder (anxiety and depression) before they get addicted to drugs.
It sounds like he has had a reasonably good home environment.
So, he may be genetically vulnerable to mood disorder and drug addiction.
He also shows strength as he can hold a part time job.
However, he keeps buying drugs.
So, his parents had him leave the house as he doesn't follow his parents' instructions at home. He has become increasingly abusive.
His parents had to use "tough love" to him.
You may contact him to see how he is doing sometimes if he has a mobile phone. Is he looking for a place to live alone?
Now he seems to be refusing treatment for his condition.
He may need counseling from a licensed counselor for his drug addiction/abuse and the underlying problems such as anxiety and depression.
If he contacts his parents and wants to go back home, his parents may tell him that he has to agree on ongoing drug treatment like working a counselor and his doctor weekly in an outpatient setting.
If he is dangerous to self (and others) due to his drug use, call a local mobile crisis team or psychiatric emergency response team designated by his city and county and give them his information (name, a location etc.) to initiate psychiatric assessment and involuntary hospitalization. Or, seek help immediately. Call 1-800-273-TALK (8255) to reach a 24 hour crisis center or dial 911 for immediate assistance.
I hope your grandson gets help and support from a drug counselor or a psychological counselor/psychologist, and/or his doctor.
Please let me know if you have more questions or I have overlooked any. Warm regards,
