If I refuse a Police Caution and receive an 'NFA' will it show on 'CRB' checks?

Got arrested while cleaning up a friends house after a huge party. was subsequently found with a small amount of class b on my person though, it was inside a tobacco pouch i had picked up during my cleaning escapades and therefore was unknown to me. I refused the police caution on this merit, arguing that i had done nothing wrong and was unaware of it being there. I was arrested and brought to the cell, interviewed, bailed and received a 'No Further Action'. Will this affect my job prospects and show up on enhanced police checks because this is a disgrace for me given that i was only really guilty of trying to help people clean their house after they had a party? Any opinions would be greatly appreciated
