See how words matter? Why do you do that? One positive and one negative on the SAME sample? I never said nor was I implying that. You're assuming the SAME sample was available for a retest, the THC disintegration rate in the sample was below the threshold for a positive, or even the initial test was flawed. Nope. Not rolling like that.
. . .and I looked. As I've also said, I've never tested positive for ANY illegal drugs. I will freely admit <self reported> use of CBD, but again, it's not about me. . .and I didn't test positive for any illegal drugs.
I'll suppose you'll simply say I've been lucky instead of saying the labels were accurate.
