I have to call bullshit on the statement.

my beautiful state into a joke. They are like a disease that has descended on Harrisburg.

Considering that the workforce of the USA worked through the 60s' 70s, 80s, and a good portion of the 90s, without mass mandatory drug testing and did fine (not counting the idiocy of corporate managements, the auto industry, heavy industry, etc).
Allowing/forcing Corporations to hold what private citizens do in the privacy of their homes and on their own times with no real consequences in regard to workplace safety due to time of inebriation vs time of any test (testing which shows a positive exposure up to and including 30 days in the past) to fight an anti-drug war forty years in the losing, might be counter productive.
Unless the excuse of rampant drug use is just the current strawman for your failed programs.

Especially the last line!

In addition to showing that our Governor is out of touch, this comment raises other important national questions.

Are employers refusing to hire people because they decide to smoke a little pot on their own time?

I can certainly understand that we want to be extra careful with pilots, bus drivers, etc. I also understand that no one should be buzzed or drunk while on the job. (My kids are subject to random drug tests for their summer jobs). I can also understand employer concerns about hard drugs.

But are people getting turned away from warehouse jobs because of what they do on their own time?

Are employers using drug tests as a way to try to screen employees for other behaviors, in the same way that they may refuse to hire people with bad credit ratings?

I remember an article a couple years ago about the huge percentage of applicants for jobs to be a Philadelphia cop never come back for an interview after they find out that there will be drug screening. I know of a guy who was kicked out of an interview to be a state cop in another state because he honestly admitted he had smoked pot within the last 5 years (it was 4 years prior). He was hooked up to a lie detector at the time. He actually would have made a great state cop.

Are we warping the type of people who can become police officers if we only consider people who have never ever been stoned?

"a study in 2011 by the Society for Human Resource Management revealed that 57 percent of the organizations surveyed conducted pre-employment drug tests on all new hires. Many of those surveyed reported that drug testing improved absenteeism and productivity. Other motivators included better safety records and lowered insurance rates."

Here's a posting about how long a drug test can detect marijuana after it has been used. It says it does not show up for long in a blood test, but can show up many days later in a urine test. I don't know the reliability of this this post:

"Our clients would hire more employees, but all the applicants flunk drug test." Well, I always call them on it and ask who these potential employers are so I can send people to fill those jobs......I have never once gotten a tip on who has jobs for friends that I know will pass the drug tests. Never once.

It sure sounds good, though, doesn't it???? The argument they used before this one was "there are no qualified applicants in PA so we have to bring experienced people from TX and OK". With so many people now training for the drilling industry, they need a new excuse. Well, too many people know the truth, and I am hoping that they vote.

in other states? Because otherwise how could you explain the fact that PA is 49th in job creation?

here's one example of many many posts on this issue:
