so im on house arrest and there is a sunoco up the road and they see posh what i want to know is if it will show up on drug tests. Ive been told by many people that it doesn't and Ive also asked cops and they either tell me they don't know what it is or that it doesn't show up, im worried because im on house arrest for smoking weed. and i get tested every time i see my p.o. so if you could help me out that would be amazing also posh is just like weed pretty much. it gives you the same high just isnt weed.
