I’m not sure how they get around the drug tests. I did some part-time work at a grocery store between jobs that I know that the assistant manager passed the test using someone else’s saliva because he was the dope dealer for the store, including the store manager.
Marijuana apparently makes me have syncopic episodes (I faint due to a rapid drop in blood pressure) so I don’t partake, so I was asked but refused to do a saliva test for the assistant manager. No hair test for me as I’m bald.
I still find it interesting that Amazon is no longer testing AND financially supporting efforts to legalize weed at the national level.
