Random drug testing

It’s a random surprise drug testing day at work.
Employees file into the main conference room, and a team of nurses pull out the testing kits.
Each employee picks up a test kit, breaks the seal, and looks inside.
I look inside my kit.
Heroin. Needle. Spoon. Lighter. Rubber tube.
Shit, I hate needles.
The credit manager opens their kit, and pulls out a joint and a lighter.
“Hey, can I trade with you?”
A nurse interrupts me. “It’s supposed to be random.”
I read the instructions, cook the nugget, and draw up a little blood before shooting it in.
