how far back do saliva drug tests go?

if i have to take a saliva drug test, how far back will it go? like say i smoked pot a week ago, will it show up? any other information of saliva drug tests would be helpful.

1. I think the weed will show up because I heard it can take up to 30 days if you don't smoke a lot it can take around 15 days, but if you exercise it can be gone faster, maybe 2 days. so start exercising.
2. Your fine, saliva drug tests only go back a couple of days. Urine is about a month for weed
