Effects Of Second-Hand Pot Smoke Could Impact Drug test

Could linger for days

You may not use it yourself but research at University of Calgary has found breathing in second-hand pot smoke could mean you fail a workplace drug test. Researchers found the THC in marihuana is detectable in the body after as little as 15 minutes of exposure – even if you’re not actively smoking it. And it can take 24 to 48 hours to clear from your system.
