It means that the test has a cutoff level of 50 nanograms of cannaboids per millilitre of urine. Meaning if you have >= 50 ng/ml of cannaboids in your urine, you fail. If you have <50 ng/ml of cannaboids in your urine, you pass. So you may have a slight amount of cannaboids in your urine still, but you can still pass. With that said, 9 out of 10 (made up statistic, but based on knowledge) drug screens out there use the cutoff limit of 50 ng/ml. Some more strict testing utilize 25 ng/ml or even less. The standard USED to be 100 ng/ml, but was changed to the 50. So basically, don't stress about this, because it's a normal number, it's not like they are doing something different in the test.

I tested my self on one of them home testing kits and I came positive for thc so I borrowed my friend's urine and gave that in the drug test. And now I m worried abt if they can detect that that I used my friend's urine. Any body has the same experience? Please let me know.

Make sure your friend is the same sex, depending upon the extent of the testing done, they can determine if the urine is male or female... and if you're pissing female urine but you're a male... they'll know something is up. I'm not sure how often this is checked though, but just know it's possible to tell.
