Can being exposed to second hand weed smoke for 2 hours make you fail a drug test?
A doctor has provided 1 answer
Probably not: The cutoff limits on drug screens are set so that tiny amounts of thc discovered are not considered positive. The cutoff is 50 ng/ml. Most second hand exposure won't get levels that high. Next, and more importantly, is why you're exposed in the first place. You may wish to reconsider whom you hang out with who may get you in trouble.
