can any of these products produce a false positive on a drug test?

First of all DRUG TESTING THREAD. Second of all you could have asked this in the spice thread.

How many people here that have smoked this stuff really believe:

Baybean, Blue Lotus, Lion's Tail, Lousewort, Indian Warrior, Dwarf Scullcap, Maconha Brava, Pink Lotus, Marshmallow, Red Clover, Rose, Siberian Motherwort, Vanilla and HoneyIs really all this stuff contains? I cant say whether it would produce a false on your drug test but as a substance there is something fishy about it and I'm sure as hell there is something in it were not being told about.

I figured I would get more help by making my own thread, however redundant it may be. Also I searched the drug testing thread.

To the poster directly above me, I think that there is something we don't know about these products too. I don't see how these drugs could have such a strong buzz and not have anything illegal in them. Although then again, look at salvia. That shit gets you lost as fuck.
