THC Drug Testing Methods: How the "Potalyzer" Saliva Test is Changing the Game
With marijuana use becoming more common and legal across many states, fast and accurate drug testing methods are in high demand—especially for roadside enforcement. One innovative solution? A handheld saliva-testing device known as the "Potalyzer."
What Is the Potalyzer?
Engineered by Stanford University researchers, the Potalyzer uses magnetic biosensors to detect THC in saliva. A simple cotton swab collects a saliva sample, which is analyzed to determine whether the user is under the influence of cannabis.
Unlike traditional tests that take hours or days to process, the Potalyzer delivers results within minutes and transmits data directly to a smartphone. This makes it a practical solution for law enforcement seeking real-time feedback.
Common THC Drug Testing Methods
- Urine: Detects THC metabolites for up to 30 days. Most common in workplace screenings.
- Blood: Detects recent use within 24–48 hours. Often used in accidents or legal cases.
- Saliva: Ideal for detecting THC within the past 24–72 hours. Perfect for roadside testing.
- Hair: Shows long-term use over 90+ days but doesn’t confirm recent intoxication.
