The time that drugs can be detected on a drug test varies depending on the type of drug test kit used and the brand of drug testing kit that is used. This is often referred to as the window of detection for a drug. As a general rule, drugs can be detected longer in urine than in saliva.
How long are drugs detectable in urine and saliva?
Cut-off levels for drug test kits are brand specific and as a guide, the window period for drug detection using a saliva or oral fluid drug testing kit are shorter than the comparable urine drug test.
The amount of time drugs stay in the body and can be detected on a drug test depends on many factors such as:
The amount of the drug that has been taken
The strength and purity of the drug taken
The body weight of the person being drug tested
The rate of metabolism of the individual being tested
Whether the person being tested is a casual drug user or a long-term user
