He had gone to Kuwait for some time, ...

That begs the question what had happened to him over there. Was he in war? Was it difficult circumstances?
Since if it was, this may be a cause for his addiction. Sad story. I am of the notion that banning products never acquires what it wants to achieve. It's when people lose faith in life and become depressed what destroys them, the substances used is 'just" what occasion/opportunity one comes across. Oftentimes this is linked to a victims mind and is difficult to cure. Addiction is tough and it drags people down who are related to the addict.

I hope for the wife and her children that they will get over this difficult times.

Greetings.
