usually about 24 hours if the test is done during the week. sometimes it is possible to get them back the same day if you do it first thing in the morning.
Anywhere from 24-48 hours usually. ive always learned that if you dont hear anything back about it then your good to go
They have one that they swab your mouth right there instant results and ive had one pee in a cup right there and test the top 5 drugs on the spot..
I would imagine that a company like western express is a urine sample... and they swab your mouth and check the saliva and somehow that can detect drug use. I used to work for a construction company that used the swab test but idk exactly how it works
