considering ive done it at least 5 times bro.

Once I failed the test but had to go back to the station for evidential test. When i got to the station I was all ' ayo officer I gotta take a piss' rocked up in the toilet, ate about half a tea spoon a there hardcore handwash/soap shit. Just passed the test.

It takes a reading of how many acoholic particals are in your breath (lamens terms) but if theres a stronger smell you have a good chance of passing, its when they want your blood you know your fucked.
