Nope, you cannot test positive due to secondhand smoke.
Burnt Toast Reviewed by Burnt Toast on . Second Hand Smoke Hey, I was just wondering if second hand smoke can cause a drug test to come out positive... For instance, if I go to a party where people are smoking, will it cause a drug test to come out positive? and If I am just hanging out with people who are smoking outside, will it cause a drug test to come out positive?
