No, being around pt smokers will not elicit a postive test result. Even in the unlikley even you inhaled enough to register anything on the test, a certain threshold of thc metabolites have to be reached before the test is considered "positive". Trace amounts from secondhand exposure won't trigger a positive result, unless, say fr example, you spent hours ina car with someone who was smoking with the windows up the entire time. In an unlikely scenario like that, I'd say all bets were off, and one may inahe enough to result in a positive result
