drug testing at hospital

im going to be getting an interview at this hospital for a pharmacy technician spot but i know im going to have to take a drug test.

ive been smoking pretty much every day for about 5 months now i stopped for a week and started again for about 3 or 4 days but ive been clean since like the 7th.. i know not to long.

my buddy has some synthetic urine he is willing to sell me and im thinking about doing that. he says his friend just got a job at the post office using the same stuff so i figure it works. im just to worried to use it i guess. i was thinking about just drinking lots of water then on the night before taking some vitamins to make it colored but i dont know if that will do the trick.

how close are the at home tests to the ones i would have to be tested on at the hospital? i really need this job so any help would be wonderful.

Drinking water in the days before the test does not help.

Take B2 or BComplex 2-3 hours before the test for color.

The hometests have a similar cutoff to a majority of the tests. If you have the time, you can buy them much cheaper online (google it). I got mine for under $2 a piece.
