TeenHealthFX is glad that you chose not to smoke. It is often hard for teens (and adults, too) to resist peer pressure and to attend events where other people are participating in illegal or unhealthy activities. Trying to find friends who share your interest in staying drug-free as well as activities that promote health behaviors may help to ensure that you can stick to your drug-free lifestyle.
Second-hand marijuana smoke (that may or may not produce "a buzz") CAN show up on urine tests. But, it will only produce a positive result the first day or so after breathing in the smoke. Also, the smoke would have to be so thick that it would irritate the eyes of both smokers and passive smoke breathers. You did not specify why you get drug tested, but you could be risking a lot by exposing yourself to marijuana smoke.
