If your not smoking or eating it, it can't be in your system. Even slight exposure to 2nd hand smoke should not be an issue unless your in a smoke filled room like Cheech and Chong. UAs have a cutoff limit that somewhat allows what could be considered accidental 2nd hand exposure. Even tests that check for tobacco use has some leeway for being around someone who does smoke tobacco.
Now, IF they wanted to do a hair sample test, and you have gotten resin on your hair...maybe a problem... I am not sure on that as THC is not activated to an active psychoactive until it is heated or dried. That is why those who juice green plants do not get high but get the benefits of the CBDs...
