THC 50 ng/mL Drug Test Strip

The THC 50 ng/mL Drug Test Strip is a reliable urine screening tool used to detect tetrahydrocannabinol (THC), the primary psychoactive component of cannabis.

With a 50 nanograms per milliliter (ng/mL) cutoff, it provides accurate detection of recent marijuana use while reducing the chance of false positives from trace exposure.

Easy to use and delivering results within minutes, this test strip is ideal for workplace testing, clinical screenings, and home use.

It meets industry standards for routine THC detection and supports effective substance use monitoring.
