I had never thought about drug testing for FAs on AA before, but when I heard some of their candid remarks:

"...I have some real concerns about passing the test right now..."
"...It is not really as random as it should be given the 3 weeks notice..."
"...More of a problem for the younger FAs based on what they test for..."
"...You are not as likely to be tested if you are doing a "standup" or a "lean to"

Not sure what a "standup" or "lean to" means, but hopefully it has nothing to do with drugs!
