You do not have to keep it warm. All you have to do is give a fresh sample of urine for examination. They will provide you a sterile bottle to collect the urine. Rest is the responsibility of the the laboratory.
Well you shouldn't use someone elses urine nor should you use illegal drugs or prescription drugs that are not yours but the answer to your question is to put in a real good ziplock baggy then place in your underwear, being that they are already warm it would be helpful if the urine was 100 degrees first then go into the bathroom punch a hole and pee. Don't get caught!
By far the easiest method, and also the neatest, most convenient, least revolting,
and most legal method, is to keep it inside your bladder until the moment comes
to deliver it.
Gargling it usually works.
Some people say that you can use soap or bleach. Others say to use someone elses urine.

Can drinking enough water help me pass a urine drug test
No, they haven't studied the metabolites of psilocybin or psilocin enough to make a drug test or a field test for them.
no. adding water will cause the result to be diluted which they will consider a positive anyway
Yes, more than enough, it only requires a few drops.
Someone else's urine for a drug test will last about 10 seconds. Urine samples are checked by temperature as soon as they are collected. Urine that has been INSIDE your body is significantly warmer than urine in a baggy in your pocket. You are trying to fool drug screeners who do this all day long. If you want to pass a drug screen, stop doing drugs.
No. The only way to pass a drug test is to not do the drugs. If you substitute someone else's urine for your own, you will get caught, and that will count as a positive result.
if you breathe enough of it
They can if you also consume cat urine. Cat urine can sometimes be enough but antibiotics help make doubly sure.
that its old, fresh urine samples are usually between those temperatures. So if taking a drug test it can spotted that someone may have brought in someone else's urine because it isn't hot/fresh
