I don't smoke but my boyfriend smoke marijuana so if I swollow his semen would it show up when I take a drug test for my job?

I don't smoke but my boyfriend smoke marijuana so if I swollow his semen would it show up when I take a drug test for my job?

Good question: My guess is that the level of thc in the semen would probably be very small, if detectable at all. You might be more likely to test positive from inhaling second hand smoke when he smokes pot near you. ...Read more

I am A frequent marijuana smoker (2-3 times per day) and have a saliva based mouth swab drug test coming up soon. How long should I stop smoking for?

I am A frequent marijuana smoker (2-3 times per day) and have a saliva based mouth swab drug test coming up soon. How long should I stop smoking for?

Depends: You are asking doctors how to beat a drug test! I would think you may not get much help here. Often, employers drug test hires because the job they are applying for requires attention. There may be a safety concern or a quality control concern. In any case, most doctors, myself included, are not likely to want to help you¨fool¨a drug test, unless total abstinence was your plan going forward! ...Read more

I have been marijuana free for 7 months.  Before this I was a chronic smoker, smoking all day every day for a year. Job drug test tomorrow. Am I ok?

Fine: You'll pass. All the thc is gone within a few weeks.

Interestingly, there are trace amounts of it in your hair and nails for months. But they won't check that.

If your job requires a random drug test, don't risk it by smoking! ...Read more

How long does marijuana stay in your system once smoked? How do you determine how long weed will stay in your system when doing a drug test or a hair folicle test I am 5'4, weighing 335 lbs hoping that helps.

How long does marijuana stay in your system once smoked? How do you determine how long weed will stay in your system when doing a drug test or a hair folicle test I am 5'4, weighing 335 lbs hoping that helps.

Depends: On how much and how often you smoke or ingest it. If it's a one-time use in modest amounts, it will only remain 2-4 days if the test used has the usual sensitivities. However, in people who smoke regularly, and in particular more heavily, thc is soluble in body fat stores and can remain there for many weeks, and sometimes even months. Hair follicle tests will show any pot use in that hair. ...Read more

How do I pass a drug test for marijuana?

How do I pass a drug test for marijuana?

Time: The only way to pass is to stop using and wait. I know of nothing that will make marijuana leave your system more quickly. As time goes by the levels will drop. If you only used on occ. You should test negative within a week but if you used regularly it can take up to 3 months for heavy users, depending on how sensitive the test is. See http://bit. Ly/1fvqnya. ...Read more

I do not smoke marijuana but failed a drug test. I do take b complex daily and ibuprofin 400mg...

I do not smoke marijuana but failed a drug test. I do take b complex daily and ibuprofin 400mg...

From what ?: Neither vitamins nor ibuprofen will make you flunk a drug test. Chance ingestion of poppy seed muffins are a classic example where a common dietary item could trigger a false positive, this time to opiates (poppy). You need to find out what agent caused you to fail and figure out how you might have been exposed. Just being in the same room with some weed smokers could make you flunk. ...Read more

Will an infrequent marijuana smoker (twice during the last month, clean before) fail a hair drug test?

Will an infrequent marijuana smoker (twice during the last month, clean before) fail a hair drug test?

Unlikely in scenario: There is no simple answer to this question. Detection time depends strongly on the kind and sensitivity of the test employed; the frequency, dosage, and last time of use; the individual subject's genetic makeup, the state of one's metabolism, digestive and excretory systems; and other random, unknown factors. ...Read more

Is it possible to get a false negative for marijuana on a doctors office drug test? At home drug test shows positive

Possible: Any test can give a false positive or false negative result. If you do weed, you know the true state and do not need to test.
For good health — Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more

Will marijuana be flushed out and will I pass a drug test in 19 days after consumption? (smoked 2-3 times last month) will it pass a gc/ms test?

Probably: This isn't the place to debate the wisdom of the cannabis laws or whether it is wise to penalize otherwise good employees. If this is an ordinary urine test, a very low level might simply mean passive exposure and it would be hard to prove you have been a user. As long as this remains illegal, please plan ahead. Best wishes. ...Read more
