How long does pills stay in your system? Is there a way to clean them out of your system?

it depends on what kind of pill. Pills such as ecstasy pills (Methylenedioxymethamphetamine), ADHD medications like Adderall (Amphetamine Salts), and Desoxyn (Methamphetamine) are all water soluble and thus can pass through the renal system to be expelled in urine. Pills such as Xanax, Klonopin and other types of benzodiazepines are fat soluble and so little molecules of those drugs will get "stuck" to fatty tissues in your body and so they will take longer to expel from your body. Weed also works this way buts its not a pill so i figured you dont care
