Hi, I have a drug test for the Postal Service in a few days because I am getting a job working for them and I know that I will pass because my system is clean right now. Do I even need to worry about smoking after the test? I am just a little worried that I may have to go back for some odd reason. Yet my fear is probably irrational.

As best I know, USPS does both post accident testing and random testing. Simple solution is to always carry a bottle of Quick Fix. I face the same post accident and random testing for my CDL, so I never leave for work without my QF in my pocket.
Hope that helps. N2

Hmmm I researched that Quick Fix product. So do you heat it every time before you leave your house?

Also, I will only be working for 1-2 months (summer job) so I don't think I have a good chance of getting tested randomly...I hope...

I don't heat it to 98 everyday. I do ALWAYS have a bottle of QF in my pocket or fannypac anytime I'm at work. I've practiced enough to know that I can go from pocket temp, around 80-85, to body temp, 95+, in around 30 minutes with only my body heat. Read the substitution guideline linked to in my signature for the graffic details on crotch and carry.
Hope that helps. N2
