there was a period when a lot of young men got their introduction to drugs through military service. Thankfully, that seems to have subsided if not been totally eradicated.
One of my sons recently finished Army basic training .. viva la difference! He didn’t have drug issues, but was totally unfocused and udisciplined. That is no longer the case.
But like an AA, I think the first step is recognizing a problem that can be solved, and in this case, Jacob found his direction in the USMC. I will pray for him and his family.
I am extremely glad that your son finished basic (in a boy, out a man) and (hopefully), is on the right tract. Do you know his future assignment?
