Please see the pics I just posted. I might have posted out of place. Both brands cut off at 50ng. Expiry date on both is into 2015. Check the vast difference.
And why would I FOR SURE test positive after only one or two puffs?? How could so little possibly raise my thc to detectible levels? And you can see that the strip on the right is clearly negative after two hits plus residual from one week ago. I've done test in the past taking two hits at a time until the test showed non-negative and it took almost 10 hits to start losing that line. Please explain - just trying to learn this tricky game. Thanks
drvrcrzy Reviewed by drvrcrzy on . Different test different results I have used several brands of THC strip tests. On one recent batch the second line is very faint even when testing a known negative and even tap water while another brand test used at the same time has a nice bold line. The test with the very faint line seems to be very sensitive to even the slightest amount of THC. After getting repeated negative results, then taking as little as one or tow puffs - the line becomes almost invisible. At the same time the other brand shows a clear second line. Rating: 5
