Compilation of UA safe drugs

[novaclay]

My hedgehog Stix undergoes random military drug testing with no beforehand notice and is wondering whether any one else with wayward pets know of drugs that for sure can't show up in a piss test.
If a similar thread already exists I apologize in advance, a link would be awesome.
If not however, Stix would appreciate if I passed anyone's input along to him.
Stix is somewhat interested in RC's and whether they are similar enough to show up or not.
From what we have read and can gather it would seem as though 2C-I and other drugs in the 2C family might be something that would be included in this compilation?
Cheers
