Detection window in urine after last use:

AMP = 1-5 days
BAR = 1 day-3 weeks
BZO = 2-10+ days
COC = 2-4 days
mAMP = 2-5 days
MDMA = 1-4 days
MTD = 1-3 days
OPI = 2-4 days
OXY = 1-3 days
PCP = 1-14 days
TCA = 1-7 days
THC = 2-90+ days
This is only a general guideline.

Contributing factors to the length at which drugs stay in the system:

Individual’s metabolism (BMI, height, weight, overall health, etc.)
Frequency used
Amount consumed
Potency/concentration of the product consumed

Prior to testing, abstain from using any THC, CBD, detox and/or diluting products. Additionally, do not drink an abnormal amount of water or any fluid. This may alter the natural state of the urine sample, resulting in an inaccurate and/or false-negative (clean) test result.

Instructions to detect the drug metabolite(s) in human urine:

1. Collect urine sample in a clean cup.
2. Open the sealed pouch by tearing along the notch. Remove the test from the foil pouch and take the cap off of the test.
3. While holding the test, dip the tip of the test (no further than the downward-facing arrows) into the urine sample for 30 seconds; do NOT submerge the entire test into the urine sample.
4. Remove the test from the urine sample; place the cap back onto the test and lay it on a flat surface.
5. For the most accurate results, read the test between 5-30 minutes after use.

The color of the T line may vary, even a faint “T” line = negative (clean) result

Positive (dirty)
