    There are many human variables involved in how long a substance or metabolite can be detected in an Oral Fluid sample. It also depends on the drug. Typically, Oral Fluid testing can detect drugs as soon as 15 minutes after ingestion, and then up to 24-48 hours after that. In some instances, the detection window is up to 4 days.
