I could go in to GREAT DETAIL to answer your question, but to make it easier on both of us....NO. NO THEY CANNOT!
The metabolites and unchanged drug that are passed in the urine.
Pretty much everything (or rather, the metabolites of it) will show up in urine.
Drug test to check for methadone metabolites in urine
Yes they will. The metabolites will show for 3-4 days after use.
Yes. It is still urine that has metabolites in it.
Drug matabolites are what your liver breaks drugs in the bloodstream into, to render them harmless. They are also what appear in one's urine that drug testing looks for.
No, they haven't studied the metabolites of psilocybin or psilocin enough to make a drug test or a field test for them.
In a swab drug test, they will test your saliva for drug metabolites and in the urine test, they look for the same thing, but in your urine. (PS. drug stay longer in your urine, than in your saliva)
Technically no, but the metabolites associated with THC (one of the chemicals found in hash) could be detectible in your urine for up to two months, depending on the level of exposure and your metabolism. These metabolites are what are measured in urine drug tests, not the drugs themselves.
Some of the drug is excreted in bodily fluids which tints it red. It's not a bad sign.
Urine screens are looking for drug metabolites. The human body breaks down the drug and the part your body can't use is eliminated in waste. The urine screen will not detect dissolved medications.
Yes. Cocaine metabolites will stay in your urine a maximum of 5 days, and hydrocodone metabolites will be gone in 3 days.
