Patriot,
Welcome to Sober Recovery.
And congratulations for living a sober lifestyle.
What a terribly sad situation for you, and your brother.
In fact, in my opinion, you brother is suffering from parental neglect, and if that fact gets to Social Services, chances are that child will be removed from the home.
I think you can beat your head against the wall trying to get your brother to listen to you, and do activities with you, considering in his life, drugs come first.
The bottom line is what would YOU like to see happen?
I think it is your decision whether or not to call and have the home investigated.
Maybe NOT a tough decision when you think addiction is a progressive disease.
Hugs to you,
And prayers for your brother...
