Yes, and they might also live long enough to decide they want to go into rehab.  I worked for the last 10 years with addicts and many will do almost anything to avoid rehab.  Right now a friend is trying to convince her highly addicted brother, who is living on the street, to go into rehab but he will have none of it.  He is in and out of jail for constant B&E's to feed his addiction and he has stolen from everyone in his family.  Also, some of these folks are being revived multiple times, sometimes in the same day.  Give them free and clean drugs and let them know there is a rehab bed when they are ready.  The cost of these revival teams is becoming ridiculous and in an era of scarce health care dollars there will be tough choices to make.
