Screening (Definition)

Examples are: colonoscopy for colon polyp or cancer; mammograms for breast lesions or cancer; psa a blood test that could indicate enlargement of cancerous prostate tissue; blood sugar or hemoglobin a!c for diabetes. Many think that scanning the whole body will pick up a cancer--in all likelihood, it will not. There also is no good blood test, yet, ...Read more

Can you fail a drug screening for marijuana if you were in the same room with someone who smoked it?

Can you fail a drug screening for marijuana if you were in the same room with someone who smoked it?

No : Drug tests are set to have a certain "threshold" where only amounts over that are reported as positive. For marijuana, it is 50 ng/ml of thc. To get that quantity in urine, you had to have had the other person blowing the smoke directly into your mouth for a long while. It cannot occur because you breathed miniscule amounts in second hand smoke. If you were in a phone both hyperventillating maybe. ...Read more

I took two puffs of marijuana 10 days ago and have never smoked before is that detectable on any screening test?

I took two puffs of marijuana 10 days ago and have never smoked before is that detectable on any screening test?

Very unlikely: Smoking such a small amount will only show up on a blood test for a few hours and on a urine test for a few days at most. A marijuana hair test may detect marijuana use for months but it is unlikely it would be positive with such a tiny amount ingested. ...Read more

I hadn't smoked marijuana for 2 months and then smoke a small amount 10 days ago . I got called for a random drug screen today after work -will I fail?

Depends: Define "small"? A small amount 10 days ago should be clear from your urine but any heavy use might show up for months (depending on the sensitivity of the test.) If they test hair, your goose may be cooked either way. ...Read more

Will hemp oil capsules make you test positive for marijuana on a drug screening?

If ingested, maybe: This is not impossible from the general rumors - disclose that you take this to the testers if you ingest it (not just a skin lotion) and let them know to look beyond that. Bring the oil w/ you for the test. Good luck. ...Read more

Is it true that taking protonix (pantoprazole) can cause a false positive for marijuana on a drug/tox screen?

Is it true  that taking protonix (pantoprazole) can cause a false positive for marijuana on a drug/tox screen?

Yes, however...: Until researching this i did not know that Protonix (pantoprazole) can indeed cause a false positive for thc, the chemical tested in marijuana drug screens. However, if you are taking protonix (pantoprazole), (pantoprazole) tell those administering the test first & they can perform further tests to distinguish thc from protonix (pantoprazole). If you test positive, saying you used Protonix (pantoprazole) will not work unless they actually detect its metabolites in you. ...Read more

I smoked marijuana for 10 years, 34 now. My passed of LC at 49. When should i get screened with lose dose ct scan? i never smoked cigs.

Other POVs welcome!: Myadvice is not to do it but I know some might differ. Congratulations on not smoking tobacco! The dangers of marijuana for this are way low - less than the ones associated w/ the imaging. Continue to care about your health, but work toward less anxiety on it. A specialist psychotherapist on health anxiety may reall help you learn how. It's a good skill set to have! ...Read more

Can marijuana get into ur system by second hand smoke to make u fail a drug screen?

Maybe,maybe not : If you spend time in a smoke filled room with users you are likely to inhale enough to turn a urine test positive.Simple exposure for a few minutes would be less likely. Either way, the odor is distinctive enough that you should be able to notice it and make an exit.Those who pay for the test are not interested in how you got it into your system.If it is there, there are consequences. ...Read more
