Will THC Vape Juice Show Up on a Drug Test?

Yes, vaping THC will absolutely trigger a positive result on a drug test. Because vape liquids contain highly concentrated THC extracts, even a small amount delivers a significant dose of cannabinoids into your system. Standard drug screenings test for THC metabolites (specifically THC-COOH), which are produced when your body processes THC regardless of whether it was smoked, eaten, or vaped.
