Single Panel THC Drug Test Dip Card from Safe Care and Mr.  Nice Guy 420
One of the easiest and most convenient ways to drug test is with the use of urine dip-card drug test kits. The urine test strip is integrated in a plastic holder for your convenience. These cards can be used to test for a variety of different substances, but this one is for THC. Their ease of use makes them a practical solution for anyone interested in implementing a drug screening process for employment or any other business or personal purpose.
 
Instructions:
Open the sealed pouch by tearing along the notch. Remove the test device from the pouch.
Hold one side of the device with one hand. Use the other hand to pull off the cap and expose the absorbent end.
Immerse the absorbent end into the urine sample for about 10 seconds. Make sure that the urine level is not above the
“MAX” line printed on the front of the device
Lay the device flat on a clean, dry, non-absorbent surface.
Read the result in 5 minutes.

Negative: Two distinct colored lines appear.  One colored line should be in the control line region (C), and another colored line should be in the test line region (T). 
Positive: One colored line appears in the control region (C).  No line appears in the test line region (T). 
INVALID: Control line (C) fails to appear.  Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for the control line failure.  Review the procedure and repeat the test using a new test. 
 
Additional Information: 
When ingested or smoked, it produces euphoric effects. Users have impairment of short-term memory and THC use slows learning. Also, it may cause transient episodes of confusion, anxiety, or even toxic delirium. Long term, relatively heavy use may be associated with behavioral disorders. The peak effect of smoking THC occurs in 20-30 minutes and the duration is 90-120 minutes after one cigarette. Elevated levels of urinary metabolites are found within hours of exposure and remain detectable for 3-10 days after smoking.
 
The THC test kit for marijuana is based on the principle of the highly specific immunochemical reactions between antigens and antibodies, which are used for the analysis of specific substances in biological fluids.
