Hair Follicle Drug Test

Ok team Reddit, I have a hair follicle test approaching in a week. I smoked for my birthday a month ago and this job opportunity just jumped out at me about a week ago. My hiring manager just let me know I’m taking a hair follicle drug test next Monday (the 24th) and I’m freaking out. I’m not a smoker I smoked once on my birthday for the first time in a long time. What are the odds I’ll pass? If I bleach my hair will I be able to finesse the test. PS: This job is life changing and I wish I had known they were still interested. I applied last summer and totally forgot about it after a few months of calling and not hearing much.

UPDATE: Thanks for all the advice, they let me push my start date out 2 months so I could pass the test lol. Hopefully the comments will help someone else currently in some way. Thanks again 💪🏾
