I think there are two reasons for drug testing.
1. One as a pre-employment screening, and I think that’s what the article is looking at, with the argument that marijuana is becoming like alcohol use.
However the MAIN REASON for an employer to test for drugs including marijuana, and maybe the only reason, is to negate an injury if it occurs while the person is using.
AND I KNOW, I CAN HEAR EVERYONE NOW SAYING JUST BECAUSE THERE’S MARIJUANA IN SOMEONE’S URINE AFTER HE’S CHOPPED HIS FINGER OFF, DOESN’T MEAN HE WAS IMPAIRED.
In the real world, the Worker’s Comp Carrier will fight the case hard and will win it. At least here in Georgia.
So why is the impairing drug alcohol rarely if ever tested for?
