Drug Test as part of Physical??!!

This weekend...I basically stayed stoned 24/7 .....
I get home today and there is a message from my doctors office reminding my parents that I have a physical tomorrow afternoon. I have to get it to make sure I am physically able to participate on the Tennis team at my school.
I knew it was coming up but not THAT close....

Needless to say I got really scared that as part of the physical they'd drug test my urine. I ask those of you that participate in high school athletics, is a urinalysis part of a physical?

Either way, I wont be sure until it actually happens....so I'm going to take a lot of aspirin and drink lots of water and vitamin waters in the hours before the physical.

I'd be pissed off like a bitch if they pull one without them telling me before hand.

Also, I was looking for a part time job and asked a friend of mine if they drug tested her before hiring...

She said no...it's illegal for them to drug test for a part time job....
Is that true?
