Drug testing city job

I’m so close to securing a job with the city but idk if I’ll pass the drug test as I only quit smoking a couple weeks ago and don’t wanna miss this chance to secure the job. Does anyone have details on when and what type of test you have to take. I wanna be honest about quitting but I know if I fail then I’ll lose my chance and be upset with myself….any ideas or information would be appreciated. When do you have to take the UA? Instantly or have to go somewhere please let me know
