I would substitute if I was out of my house cause if something went wrong my parents would flip a shit. My little brother is applying for the same job and has to take a drug test the same date I go in. He doesnt smoke weed cause' he thinks it will stunt his growth(lol) so I thought about having him piss in something before we leave our house and tape it to my leg and put a hand warmer down there but that is to risky for me. But I should pass without smoking until that first Test date so I'll just wait until after that to smoke again. And I will probably go to walgreens and get another At home test kit to test myself before I go in. If I fail it I'll choose my second test date to give me more time, but if I pass then I'll choose the first one.
