If I took a total of four ambien, and 1 hydrocodone, I am 145 lbs, and 25 years old and I have a drug test in 6 days, will I pass?

Yes, most likely. It's different for everyone and depends on your body fat, metabolism, and enzymes. Nonetheless, 6 days should be good and you took a very small amount of hydrocodone. Ambien is not usually tested for.
