Idiots on here. The person is asking as obviously they are trying to use someone else's urine to pass a drug test. If a 50 year old man turns in urine that is determined to be from a 16 year old man, and they can tell, that means the test is failed.

no... but, drug tests show how old the urine is and the urine is always tested with a thermometer to make sure that it is YOUR body temp... the best way to pass a urine test is to know how long drugs will be in your system dont smoke weed one month before a drugs test dont take exstacy, cocaine, ketamine etc 1-2 weeks before a drugs test... LSD on the other hand (my specialist subject) cannot be traced after 6 hours of taking it... NO drugs tests test for acid :) hope this helps :)

No, three day old urine will probably not be useful for a lab test. Urine should be as recent as possible - preferably less than an hour old when tested.

Can old urine be used in a drug test?

Yes, but only if it has been freezedried and reconstituted within 2 hours before the test. Urine generally is of no use once it has been exposed to the air.
