The situation I'm wondering about is if someone were stopped and traces of an illegal drug were found in their system, could they be prosecuted? I presume traces of most substances could be detected even a few days after they've been taken. There is a limit for alcohol (80mg/l or something like that) which ensures that only people drunk at the time are arrested, trace ammounts of alcohol in your body are ignored. Is there a similar limit for cocaine or cannibas? Could someone who smoked or snorted something a few days ago be done for drugged driving?
