Kimmie, my AH talked of suicide also when doing meth, and also did lots of crazy stuff that his normal self wouldn't have. I think the meth does affect their minds somewhat, and affects some people worse than others. Try to enjoy the peace knowing he is not on the streets anymore, that you know where he is and hopefully he'll participate in maybe the aa or na meetings they may offer where he is and pick up some tools of recovery. I've read other recovering addict posts that have been through many rehabs and each one helped them a little on their way to recovery and finally they got it. Hopefully this will be your sons and my AH time to get it. And you're right, God will take care of them! I just have to remember to stay out of his way sometimes.
