Wrong. Not in a standard one, but they can easily test for it. I failed for LSD when I was on probation.
sweet, thanks for the info.but on topic again, unless you are tested specifically for the WHOLE range of drugs, or psychedelics especially, you wont show up with LSD. most piss tests are for alcohol or cannabis "abusers"
3 days in piss, but that test ranges around $800 so it's unlikely. Honestly if you know when your being tested just wait. If not proceed at your own risk.
