My real question here, and I am serious, because it jumped right off the page for me, is whether or not the USPS hires people who fail drug tests? An applicant for the USPS tests positive for marijuana, and then they hire him? Is this true? I find that hard to believe, but that seems to be what the last bit of "information" in the quote above is indicating. Something's not right about this study as you're describing it, I suspect.
I can't see any federal government agency hiring someone who fails a drug test, when they don't have to. "This applicant is breaking federal law. Let's hire him!" Yeah, sure. I also find the stats you cite from that "study" highly questionable.
Maybe you could provide a link to this "study" of postal workers?
And BTW, CJ, I worked for the USPS for a number of years. One more reason I highly doubt what you are saying, both about hiring people who test positive, and those inflated, over-the-top statistics re absenteeism, etc. I think, from my personal experience, that this study, which I urge you to provide a link or citation for, is being described by you inaccurately. To say the least. And before you ask, the USPS did not administer a drug test prior to hiring me. Had they done so, I would have tested positive for marijuana. And they would not have hired me at all. And I like to think, for the time involved, that I was a model employee.
"Consequently, someone who smokes marijuana daily may be functioning at a reduced intellectual level most or all of the time."
CJ, your's is nothing if not the voice of inexperience and misinformation, IMHO....
