I vote for subbing! I subbed. If its for a job you should most certainly be allowed to pee unobserved. The only way to fail with synthetic is to get caught. The labs cant tell the difference. I can tell you I was a lot more calm, KNOWING I had passed then I would have been wondering if I had. Mine went smoooooth. Real smooooooth! Then you can keep smoking and be the happy flourpower I know you are!
