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

Ok, you are wrong, weed has about 10 times the amount of carcinogens as tobacco.  The last time you smoked weed is almost irrelevant.  It's a matter of how much have you smoked in the psat month?  Canabanoids also can be stored in fat cells.  If you smoked a lot (say two bowls a day) every day until 3 days ago you will probably fail.  If you happened to exercise a lot the day of and before the test you will probably fail (if you used to smoke a lot.)  If you smoke two or three times a week you will be fine, but might show up as traces (not proof in a court or to a PO)  Also, the fact that 90% is your sisters will help you greatly even if you do smoke a lot you could still only show up as trace amounts.  If it comes back positive you won't get a retest, I'm sorry... if it comes back traces you MIGHT get a retest or they will just say good bye.

If you took two hits and haven't taken anything else, then more than likely it won't show up. Urine samples make up a majority of the drug tests used today and they are not that accurate. I used to administer them and there are a certain percentage of "allowable" residues that show up on the tests all the time. These low levels are included because of all the false negatives that would show up if they weren't. Therefore you should be fine. But as mentioned, you should always drink plenty of water to further dilute the sample.

if it did show up, it would only be trace amounts.  from this, all they actually can prove is that you have been around it, not smoking it.

Military only tests when they suspect drugabuse and when folks enlist. They don't test hair and nails. They take blood and test all in one including aids and hepatitis and tetanus and a lot more. (Including drugs). And when they suspect that you use drugs they might "offer" you a urinscreening. That's very easy with a paper they put in and it can't be the wrong color or so. Hair and nails, like a hair from your butcrack that's been there forever is not a standard testing object.

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!!

This is an easy question- DON'T DO WEED IN THE FIRST PLACE!!, Gawd, everyone and there mother checks for drugs, for employement, sports, you name it. You can even buy home drug test kits at certain drug stores. SO if you did weed, the only thing you can do is wait, a loooonng time, because traces can be found in your hair as well, so you have to grow your hair out completely after you stop using it. And some tests include not just pee or blood but hair as well. So you better have a tow or three months before your scheduled drug test.

For an urine or blood drug test, THC metabolites [the active ingredient in marijuana] show up for a period of 28 to 30 days after the last time you smoked. If a hair sampling drug test is done, it may take months or even years [if you're long-haired] for THC traces to disappear completely from your system. But, if you smoked for medical reasons [marijuana is a medically recognized treatment for nausea and vomiting in cancer patients undergoing chemotherapy; it even comes in pill form, under the brand name of MARINOL; get your oncologist to prescribe it for your use], then you can't be discriminated against or otherwise penalized if a positive result comes back. It's unconstitutional and illegal to do so, because it may constitute discrimination against your person in basis of a disabling condition. You may want to consult an attorney regarding this issue for further advise. Good luck, and hope that you get better real soon.

Not likely. Not only that, most places that test for drugs (especially if this has anything to do with "the law") also test urine for dilution, since this is the most common method people tend to use to try to mask (or get rid of) the drug from being detected in their systems. Usually, what else is "looked for" are the common ingredients found in your over-the-counter type supposed "remedies". None of them work anyway, and if your urine is found to have any of those common components (like in those drinks you can buy that supposedly work)- or your urine has too much water in it, or the ph level is off, usually this will count as a "dirty u.a.". Meth usually takes 7-10 days to clear the system, sometimes longer, and there's really not much you can do at all to "speed things up". Your best bet- in the future, is, to not use the drug.\n\n-Tera (time4u420@yahoo)

I have known about drug tests coming up positive due to specimen mix ups and faulty testing (urinalysis).  If you do get another chance I would make bloody damned sure that I wasn't around anyone who IS using, smoking, injecting, etc.  Even when you yourself know that you are clean, there is an old adage that goes:  birds of a feather flock together.   Good luck.

Don't use again!  I've been clean for 12 years...I'm still afraid there is something in my hair.  THC is stored in fat cells.  When I lost a lot of weight I was worried that the fat cells I was killing was releasing THC into my body so I wouldn't be able to pass a urine test.  I never did find out if that was true because I was afraid to ask the doctor.

It depends what is being evaluated. In drug testing, urine can be kept for a long time, years even.  For all testing, if it is stored properly - long periods may elapse as well.  If the pourpose is to evaluate for infection - immediate evaluation (same day or 24 hours) is best.

I would say yes, Usually those tests are based solely on the use of drugs regardless if you used them legally or not.  Employers don't want stoners.  You can be refused a job for any reason that is not discriminatory in nature based on race, religion, age and sex.

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.

If the drug screening uses a hair folicle test then yes. Second hand marijuana smoke can show up in a hair folicle approximately one month after exposure. However, since that particular screening is very expensive most employers use a urinalysis or blood test, in which case most people will pass the test.

Depends on whether or not you are a chronic user.  If you used frequently and for a long period of time, it may show up in hair follicle tests for upwards of 60 days.\n\nHowever, occasional users will test positive for marijuana use with conventional urine tests for between 14 and 30 days.  The less frequent the use, the shorter the time.
