OK thanks.
As you described in your initial post addiction is a progressive illness that gets worse not better, if left untackled.
The drugs you mention he is taking are highly addictive. I know when I was using then I was pretty much out of it and didn’t really know what I was doing half the time even though I thought I did – this stupor I got myself into is likely the reason for most of the things you mentioned in your post.
I see counselling and treatment is mentioned – what is happening with that?
