How Exactly Has Meth Affected Your or a Friends Life. Does Rehab Really Help?

just so you all know (since some of you are bad mouthing me) I am doing some research for a rehab center where i live. We are wondering how many have actually had a good success after rehab with meth use. And wondering how it has affected the person, as well as the friends and family. but i thank all you for bad mouthing me. and just assuming i am a “ho” but i am more thankful for the real honest answers. the ones that answered the question and didnt attack.
