If you blow smoke in someone's face, without them actually toking, enough smoke can get them "contact" high, meaning that they came into contact with THC through the second hand smoke, and thus, became high. Also, the contact high usually never shows up on a drug test..
Mike got his cat contact high by bringing him into the bathroom and toking on two flat blunts.
