if you think about it if you can keep with your story you can never get caught when you are high. sure you can get drug tested but that doesn't mean you are high at the time.

just because someone sees you have red eyes or your eyes are closed some doesn't mean you are high. allergies is a common thing if you guys didnt know. just give in because they really have no proof. if you smell like it or have it on you though, well then you are sort of screwed haha.
