Can employers still drug test?

if legislation is passed in michigan to decriminalize 100 grams of marijuana,will employers still be able to deny you employment for testing positive for marijuana for a pre-employment drug screen?

if legislation in michigan is passed.wouldnt they treat marijuana like cigarettes?they could just test for the real drugs like cocaine.they would just take marijuana off their tests.someone please tell me im right

The problem with drug testing, is that it determines the use of a drug.
It however, does not differenciate as to whether or not you use the drug at work. Marijuana for instance will show up in your system for weeks, or even months. Long after the effects of the drug have worn off.
Realistically... an employer really doesn't have to list a reason for refusing to hire somebody, and can probably manufacture a reason to terminate employment if they want to.
So it doesn't really matter if they can legally fire you for the use of something that isn't illegal.
By the way, just because something has been decriminalized, doesn't mean it's been legalized, just that all criminal penalties for it have been removed.

Just because use is legal doesn't mean they have to hire users.

Drug screens are in place in order for employers to determine whether or not a person could be impaired, due to the use of any type of drug in a potential employee's blood work--whether marijuana is legal or not.

In today's America, you no longer have any rights to privacy regarding your body. Your employer can drug test whatever and whenever they please.

YES

yes it is at the employers discretion. Alcohol is legal but if u have vodka in ur pee they won't hire u.
