Marian...just another welcome, everyone has answered your question so well before me.
I am also a mother of an addict and we had to go the exact same route. We had to kick him out with no home, no job. I would have never gotten through it without all the help from the great folks here. As mom's we know how hard it is for you, so keep posting, you are definitely not alone!
