I work at a lab so I also know if they do test
her for this an it does show in
her system, they can tell how much is in
her system. They may keep her longer because she is hindering the healing process as well as some sort of punishment for usin in the facility, I also know when in rehab, u get tested on a regular basis. The only outward sign you may see in her if she is using again after she returns is either mood swings and/or she has way more energy, upbeat, happier and/or talkative.
