Saliva Drug Testing And One Important Question

Hi I just recently had a drug test(oral swab) yesterday for pre employment. I am a very frequent smoker every day toking but I stopped smoking on Monday this week(test was yesterday on Friday) so I know I'm probably good in that area the only thing that worries me a lot is on Thursday I was using the nickel trick with my grinder to score a lot of keif and when I go to clean off the keif scraper I stupidly put it in my mouth and licked it off -____- I didn't think about it until well after the fact. I did this at about 6 pm on Thursday and the drug test was at 4:30 pm on Friday do you still think I passed it? I also brushed my teeth and tongue and gargled all vigorously before my test I think I will pass it but I'm worried about the small amount of keif(literally not even measurable was on a real tiny keif scraper) making it come back positive please help qualm or reinforce my fears I need this job so bad.
