They do and will show up but it requires a different test. So again as others said, not confirmed. Fact is crazy crap like this has occured from the others drugs esp PCP.
Andrew, a 22lr is, as iv said before one of the absolute best shtf weapons. Super cheap to stock up and frankly you can take any animal in north america with it and the right ammo. CCI stingers, CCI velocitor, CB shorts, remington yellowjackets, federal lightning(my rifles favorite) etc. its easy to find and would make an easy bartering tool.
As for prepping for zombies? Nah im not. I do try to prep what I can simply because id rather be prepared than not.
ya but not as many cases that are popping up like now...but they dont show up on parole or probation drug test thats why so many people are on it and tripping out cause they can get away with it trust me i know im on parole. but everybody will find out soon enough
