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
