A sensitive cannabis test detects THC (hashish, marijuana) in urine and drink samples 7-80 days after their use, depending on the amount and regularity of use.
Sensitive THC test sensitivity 20 ng/ml. Note. simply staying in the same state as marijuana smoke can cause a positive result in the test.
Instructions for use, sensitive cannabis test:
The head of the test strip marked with arrows is immersed in the urine or drink sample to a depth of about one centimeter (the maximum limit is marked on the strip) and held there for 15-20 seconds. Then the strip is lifted off and placed horizontally. The result is read after 5 minutes (no more than 10 minutes).
- Two lines (C and T) is a negative result, i.e. indicates that there is no observed amount of cannabis (THC) in the sample.
- The C-line alone (i.e. the absence of a T-line) indicates that the sample contains cannabis (THC).
- In the absence of a C-line, the test has failed and must not be interpreted in any way.
The active substance in cannabis Δ9-tetrahydrocannabinol (THC) is stored in fat tissues, from which it decomposes slowly. After stopping long-term cannabis use, the cannabis test can remain positive for up to more than a month.
