You can do the Jell-O thing if you think your going to get tested. But if its a random and you don't have time to do this stuff. Tell the nurse you went to the bathroom before you came, they will let you have water, or a certain amount of water, anyways, when you finally go in there...piss in the toilet as much as you can then into the test cup, because THC rest's in the bottom of your kidneys thus the closest thing to your bladder. Yet again as he says it will still show up in your system, but so low of an amount that it doesn't count, but they never tell you that.

P.S. I just read some others notes, yet again, just do what mine stats if its a random drug test, that way you don't hold urine on your person that looks all bad.

I know this works, because I know all people that grew up on the streets, and this has worked for them when it came to THC problems.
