You’d lose your security clearance over legally putting a marijuana cigarette in your mouth and demonstratively not inhaling, in the context of an interview made for entertainment purposes?
Absolutely no law is enforced 100% of the time on everyone equally. There's always a political/social calculation being made and balanced. It's childlike naivety to believe that perfect enforcement ever could (or should) be the case. Akin to believing Santa knows if you've been bad or good so be good for goodness sake.

The security clearance in question is federal.
