Reporter: “Dr Pokeinthepus... did you run any definitive medical tests that would determine if chemical traces indicative of tobacco use were present in the president's blood stream”?
Dr Pokinthepus: “Why no... to my knowledge... there were no such tests administered”.
Reporter: “Then how did you know that the president was tobacco free”.
Dr Pokinthepus: “I just took the president at his word”.

At first glance, I though this was Dr. **Potemkin**!!! :-)
