My friend who is a heroin addict and went to jail said that during the withdrawls your is a seperate area of the jail where they monitor the person withdrawling. Then after about a week or so when they are done they go to general population. I think this is the best thing for her. She will be sick for 4-5 days but after that she will feel alot better and maybe this is what she needed to get clean. They also have meetings in jail recovery meetings. My sister goes to them once a week. 6 mos is a long time to really focus on recovery and figure out what she needs to do to stay sober. Good for u on not bailing her out if she is dope sick the first thing she would do is use to make herself not sick. Heroin w/d only lasts 3-4 days. Stay strong.
