wicker nervous about test

[90notch3]

alright so i went for my second interview for this job that my mom works at. i believe they will be calling me soon for the position and ill have to take a drug test at somepoint. i stopped smoking on thursday and will not smoke untill after i get the job. but im very sketched out because it is not an option to fail because its my moms work. i plan on trying to substitute and use the dilution method. im going to use a friends piss in a small bottle in a pair of tighty weightys. my mom says they leave the door open...but if i get sketched out there for somereason i will have used the dilution method and just try pissing. ive been drinking alot of water, im 6'1 about 150 pounds with a crazy fast matabolism. do you guys have any suggestions im just sketched out about them for some reason patting me down or the dillution not working. any suggestions or other ideas would be great!
thanks guys for the help and great information.

Since this is an employment-related test, the techs are not allowed to frisk or otherwise touch the donor in any manner. That constitutes groping and is against the law.
The techs can only have you remove jackets, hats, and have you empty your pockets.
