Hi and thanks for the query.

These can stay in your body for up to 20 to 30 days depending upon how much fat content your body have.

There are three possibilities for your test. One is that your first test was false negative and second is testing positive four hours later is because your fat has released the drug slowly after those four hours. Third is that some of the drugs can cause false positive result in benzodiazepines test these include Tolmetin (Tolectin)Naproxen (Aleve)Etodolac (Lodine)Fenoprofen (Nalfon). Oxaprozin (Daypro)Sertraline (Zoloft)..

Let me know if you have further questions.

Please do leave a positive rating.

Best wishes.
