My friend was in aarc last year. They said she tested positive for all kinds of drugs even though she only smoked pot. They said the pot must have been laced with stuff, including heroin. She was only 17.
My friend got out, got pregnant and now has a beautiful little baby. She lives on her own and is away from aarc. She has a wonderful new boyfriend and a bright future in spite of it all.
One thing worth noting was that she told me they kept her so drugged up for the first few weeks and they said it was to help de-tox her. She thought that was very wrong.
