One underappreciated aspect of this. They will ignore marijuana at time of hire. But they will absolutely test you if there is ever an accident or if you are injured at work (even if you just strain your back picking up a heavy object) before you see an occupational health doctor. If you come back positive in the course of injury, they won't cover your workers compensation bills. They'll fire you (for being intoxicated) and you'll have to cover your own medical expenses without access to workers comp coverage or the emoyee health plan (because you've been fired).

The article seems to allude to that:

“If a delivery associate is impaired at work and tests positive post-accident or due to reasonable suspicion, that person would no longer be permitted to perform services for Amazon,” she said.

I mean, this has always been this case with alcohol hasn't it? it's legal to consume but not while at work or operating vehicles. if you do so and injuries/death result, you are held liable.

The test for marijuana aren't as useful as the tests for alcohol. Marijuana test may still come up positive long after you are impaired.

Yes, THC is lipophilic. Heavy users can take as long as 30 days to test negative.

Even longer, personally failed a drug test after not smoking for 4 months. I believe it's something to do with modern test involve looking for what THC breaks down into as the body processes it instead of THC itself.

Is that not a different kind of test, for current presence rather than past use?

[caymanjim]

There aren't any reliable tests for active marijuana intoxication. Blood tests are sometimes used in DUI situations, but the science is weak. It's not as definitive as alcohol testing. You can test positive for marijuana in hair and urine tests weeks after last use, and test positive in blood tests well beyond the point of intoxication (like the next day).

I has a friend who tested positive on urine test despite not ever consuming MJ. Turns out he took ibuprofen and the test came out positive.

Even if your friend truly did not consume marijuana how do you conclude it was the ibuprofen that caused that failed test?

[petre]

It was the only medication he was taking at the time because of a tooth ache. The authority requiring the test let it pass.

[14]

I would still want to rule out other factors before concluding ibuprofen had anything to do with it such as a mix up in samples or the tester doing something wrong like contaminating the tests. A single data point in this instance truly shows nothing.

No, cannabis is quite unique in that thc metabolites get stored in the fat, and there's not really a way to just check for acute intoxication. I've had friends who were heavy, heavy users who took 1.5 months to clear up. (Casual smokers can clear up in a few days or 1-2 weeks at most)
