Military urinalysis started in 1981, IIRC. I enlisted in 1984, and remember whizzing in the bottle when I got to Great Mistakes, and innumerable times thereafter. None of this, "Hey, in three days" crap. You showed up, the Chief said, "The magic number today is, "X" so YOU, Sparky, will provide before you leave the boat," etc.
Then I left the Navy and every job I've had has had drug testing as a condition of employment. My last job, if I didn't supply (ON SITE) within two hours, that was considered a refusal to provide and you were fired. Period. A positive test was a termination, although you could in theory reapply in five years, although it was all but certain you'd never get hired at any nuclear plant anywhere again.
To paraphrase a certain guy, "You don't want to piss hot? STOP TAKING DRUGS, ASSHOLE!"
Sparky, I believe it was in 1981 a start up operation and the mistakes were carear ending.
In just a few months after the piss tests started, a good 40+ of Mormon sailors were given the bum's rush and these kids did not even eat chocolate or drink coffee. False positives.
I at the time was doing rip outs and lagging on military ships and for sure the smell of pot was everywhere, from the gang plank to the bilges.
On one ship, I believe it was a good 40 feet from the deck to the engine room. Ladder straight up for access from the top. OOH OOH that smell, by the time I climbed slowly to the deck I was in a very good mood and have little memory of the job I did on that ship.
The words, Go smoke a roap come from the old time Navy, sort of liking cat nip, makes one woozy and sick.
