idk but firestone fucked around with me when they knew i failed. They had me come in and sign bullshit for a additional background check and the manager was a pussy ass bitch and didnt even call me to tell me i failed. They made ME call the fuckin lab and they told me. It took about 7days of bullshit to finally find out that i failed,

soo in your case idk they shouldnt take more than a day.

my last drug test for employment i got the results in 30minutes that i passed and i started the next day soo thats my slice on thangs
