NORML says a saliva test can only be detected 1-2 hours after smoking, and sometimes not at all. http://norml.org/index.cfm?Group_ID=6991 I was planning on smoking only on days where I didn't have to work the following day but I have some white rhino I want to smoke tonight and tomorrow is my first day. I wonder if I would get a random test on the first day but according to NORML it wouldn't matter. Is this true or what? I'm working in the Deli at Publix by the way and I already passed the pre employment test but I heard they do random tests.
