First and foremost thanks to all who have created this fantastic board as well as thoughs giving information.

Situation:
Getting a job w/ local hospital
Almost 100% positive they are going to use a UA for drug screening
And Blood test for other things such as Hep B etc

Heavy Smoker
5'10 175lbs low metabolism

At first I was thinking of trying to mask my piss. After doing some reseach on this site it seems that subing would be the best option. I have a couple of issues that are keeping me up at night, that and not smoking the green.

-since they are doing blood test will they do any cross examination that would prove that it is not my piss?
-should I also mask, as a back up plain. (stupid me trying to smoke b4, but I know it is not worth it so I will stay clean and detox)
-I went to Wally World and they do not sell any digi therm. that do not beep. If anyone as used a Vicks ComfortFlex please let me know how they disabled the sound?
UPDATED: I open the back panel and disconnected the speaker wires. KUDOS TO ME

Any other thoughts or suggestions would be greatful.
I will deff. smoke a big fatty w/ whoever helps. virtually 420

THanks so much
