Can a person test positive for THC from second hand smoke?

Passive Exposure, and Why It’s Not Enough. The amount of THC you might inhale through second-hand smoke is minimal — to be more precise, about 100 times less potent than THC levels from active exposure. Therefore, assuming you yourself haven’t been smoking, testing positive for THC just from second-hand smoke shouldn’t be a concern.

Is it possible to get a positive drug test from marijuana?

While it is possible that extreme marijuana smoke exposure could produce a positive urine test, this occurrence is likely to be rare and limited to the hours immediately after exposure, according to researchers from Johns Hopkins University.

Can a second hand smoke lead to a failed drug test?

What’s more, studies from the 1980s found that second-hand smoke could lead to a failed drug test. Fortunately, these studies were inherently flawed, and exposure to second-hand smoke — or what many people refer to as a “contact high” — is not enough for you to test positive for marijuana.

Can a non smoker pass a drug test?

When the researchers used a more sensitive test, which is usually not used in workplace drug testing, they could detect lower THC levels, but only for 24 hours. Non-smokers in the ventilated room did not come close to meeting the threshold for a positive drug test, Newsweek reports.

Can you test positive on a drug test after secondhand smoke?

Can you test positive on a drug test after inhaling secondhand marijuana smoke? Probably not in most cases. But it is possible to detect marijuana in drug tests after exposure in an unventilated room to larger amounts of THC, the ingredient in marijuana that causes the high. Drug screens can look for THC in your blood, urine, saliva, or hair.

While it is possible that extreme marijuana smoke exposure could produce a positive urine test, this occurrence is likely to be rare and limited to the hours immediately after exposure, according to researchers from Johns Hopkins University.

What does it mean to have a positive THC test?

A positive or detected initial THC screening result means that the person tested may have used marijuana. Since screening tests are not definitive, confirmatory testing is typically done to verify the results.

Can you smoke pot in a room with someone else?

If you’ve ever been in a room where someone else smoked marijuana, you know just how easy it is to inhale the smoke yourself. You’ll likely leave with your clothes smelling like pot as well. For those that have work or educational commitments that require staying free of drugs, this may cause concern.
