urine test to detect cannabis does passive smoking show positive?

It depends on the amount you have ingested.  Generally not from a contact high though.

A board is going to believe evidence over ANY testimony. Get an independent lab, like omega labs, to do a blood and hair test for drugs. If that shows up negative, submit it and respectfuly requests anothertest to be done by the Navy. It is possible to pop on a a urine test and not have done drugs. If you are familiar with the sytem, all it takes is someone to switch your clean urine with a buddies dirty urine. However, conspiracy theories wont help you, only evidence. Good luck sailor!!!

Touching weed has nothing to do with it.  Now if you were next to someone you are inhaling what they are smoking.  It's like cigarette smoke, yah know they say second hand smoke is worse than first hand smoke.  It will show up on a drug test because it will be in your system.  Now how much you inhale depends on how much you breathe in.

Nicotine can be detected in habitual smokers using commercially available tests for urine cotinine. Smoking one pack per day of cigarettes will result is a positive test even up to 2-4 days after stopping smoking. The threshold for a positive test is unlikely to be met by a nonsmoker exposed second hand. A casual smoker may not be detected 24 hours after cessation. Nicotine screening is not routinely used in drug testing. An employer may choose to screen however due to the nature of one's job or the higher incidence of health problems associated with smoking.

2 weeks. but there is a loop hole. as long as you dont scratch off any skin onto the mouth swab it might not detect anything. a friend got stoned right before the drug test. he pasted because his mouth was so dry and he rubbed the swab on his teeth, not the inside of his cheek.

They don't check for anything except illegal drugs, however, some OTC (Over the Counter) drugs or high levels of vitamins in your system can cause false positives (Some decongestants can cause a false for Marijuana).\n\nI wouldn't worry if you're only taking a small dose though...\n\nI'm guessing that they're just really busy, or waiting for the results.  These things can take a couple weeks sometimes because of red tape.

NO it will NOT show up! I had the same issues once and had to take a urine test for a job and it came up negative, I was even sitting next to my friend while they was doing bong hits......

You can't.  It will test positive in your urine for over a month if you have been smoking for a long time.  It will test positive in a hair follicle for 3-6 months, depending on how long/how much you've used.\n\nOvernight?  Absolutely no way.  There's nothing you can drink, eat or do to get it out overnight...or two nights...or three nights...or

i was in the same situation as you. i smoked 2 days prior to the mouth swab and still passed.  jus make sure that you get as little saliva on the swab as possible... maybe eat/drink somthing before hand.  I'm not a chronic smoker (sorry for the pun), but i do it once in a while... \n\n"In a study using RIA (Radioimmunoassay) test, cannabinoids were detected in saliva 4 to 10 hours after subjects smoked a single marijuana joint."\n\nYou Should be fine... Good Luck.\n\n-CAP

No. Since a person simply in the same room as another person smoking a joint will receive significantly less smoke (and therefore THC) than the person smoking the joint, there will not be enough to be detected. This is unless the person in the room intentionally tries to inhale as much smoke as possible.\n\nBy the way, being in the presence of a crime can make you an accessory to the crime. Might just motivate you to throw out the dope smoker in your house.

Read your question and I'm not sure why they said you would fail. Those tests done have detectable limits they go by and it takes a bit of use for it to show up. A couple puffs probably wouldn't even show up in a urine test.\n\nEDIT\nMy guess is they just don't know. People go off "myths" and hearsay with stuff like that. Sort of like all the remedies they have to pass drug tests.\n\nGood Luck

Saliva tests can detect THC in your system if you've smoked anywhere from 72-48 hours before the test.  If it's been longer than that you are in the clear.

Sometimes certain drugs can be found in common over-the-counter medications (thus the reason why they normally ask you if you have taken any medication before the give you a urine test). Also, it has been shown that certain foods you eat before taking various drug tests can cause a positive result for a drug. An experiment was done where a person eat a bagel with poppy seeds on it and then took a urine test. the person tested positive for opium! Go figure!!

Urine drug testing is the most commonly used and most inexpensive from of drug testing. While most drugs will be washed out of your system after a few days, marijuana will test positive for several weeks after the last use. This is because THC is not water-soluble and will actually "stick" to the fatty tissues in your body.

It doesn't take much to test positive.  The stuff can show up in urine up to 30 days later.  The more often you use the higher the level builds.  It seems like the pot is already destroying your brains ability to think.  Hope you fail and learn a lessen.

Nope.  If you think you can fool a drug test, you're probably still high.  \n\nYour best bet is to come clean with whomever is administering the test BEFORE you pee in the cup.\n\nThen, quit smoking and get a life.

If it is a drug test then they probably won't be testing for hormones or pregnancy. BUT... some cups have a color coded temperature gage on the side. So they can tell if the urine is fresh by the temperature. If it is room temperature, you are IN TROUBLE !
