At least you're peeing bro. I have a hair test and that's for sho gonna pick up something crazy unless i get some good tips.
For you tho bro, you should be good if you're clean for about 8 days. While looking for help for me i found this chart--geeky but layz it out nice:
Trimega Laboratories - UK Hair Drug Testing
Site says that saliva has the shortest detection. Can u request what kind of test you're getting? prolly not hey? lol.
