If you really wanted to do a scientific study on these myths you really should have access to blood testing. You would need to get accurate THC metabolite levels and urine levels can fluctuate from fluid intake. Home tests also don't give you a number only higher or lower than 50 ng/ml.

What goes on at a lab is no big secret. Most of the time immunoassay tests are conducted using machines (not test strips) and all non negative results are confirmed using GC/MS.

Debunking the drug testing myths So I was watching myth busters and with all the drug testing on my mind lately, I thought ti would be a cool thing to write into them to see if they can bust drug testing myths for all us smokers out there (I bet Adam and Jamie light up, come on). I imagine they wouldnt due to the nature of the myths, so I started thinking how I myself could do so. I was thinking of getting all the information of how drug tests at labs are conducted, seeing if I could purchase some high quality drug test kits, Rating: 5
