thc is in your poop, about 40% more than in your pee. why dont people poop test? seems more effective
ahhhhh you got me, but when it comes to cost, how much more do you think poop tests cost ya know? compared to pee tests of course, hair and blood is different.
Who really wants to analyze poop? Even the people who do it for a living wouldn't want to.(well, maybe some do?)
