I've never smoked, but I wonder if I'd like my doctor to be high when he operates on me, or for an armorer to reassemble my rifle while high. Does marijuana influence attention to detail? Is there a way to ensure that people don't get high while at work, that they stay sober on the job? Anecdotally, from watching high people while I was in university, I don't think I'd trust their giggling selves with my life.
The way to ensure that people do a good job is fire them if they don't do a good job. No need for indirect methods.
I'm not so sure of that. Failing a marijuana drug test means that there's a measurable amount of THC in your body.
How about an eye surgeon that just had 3 big coffees? I think the fact that you haven't smoked makes your perception of cannabis' effects wildly out of step with reality. I wouldn't trust any of the sober university students I knew performing surgery on me.
In fact, it appears to be routine and required of medical residents in the US. Which is ridiculous.
Obviously this doesn't apply to surgeries, and I can't think of a surgeon who would smoke weed and operate. But in a hypothetical situation, it could allow a person to perform better.
However, if your doctor smokes weed or drinks alcohol in his free time, it doesn't make him a bad doctor.
The real world is more shocking. I know many doctors and surgeons who use cocaine. And there are surgeons who will intentionally do bad surgeries because the profit motive is so high.
Three doctors including a surgeon were arrested today (one from Beverly Hills) and are facing 50+ years in prison for insurance fraud.
Human nature is a scary thing.
It's foolish to think people will just throw caution to the wind and get high before doing their job.
Other than that, consumption of cannabis is correlated with a bunch of stuff that an employer may want to avoid (for instance increased impulsivity [1])
Given the fact that employers routinely choose to not hire somebody because of even the slightest misgivings, not wanting to employ a pot smoker can hardly be called irrational.

You can't tell, and 50% of the sales at Tucson dispensaries are edibles and concentrates.
So you will have to judge on the work, not if they are giggling. You should be more concerned if your surgeon is ethically compromised so that he would operate impaired by anything - no sleep, alcohol, weed, prescription pain killers. Same for anyone in a life/death job.
I own a factory, and use it for pain management. When I am using it (that day) I won't drive the forklift or use any machinery. I could hurt myself or others by being lost in a weed fog. Instead I do emails, meetings, R&D, etc. while sitting at my desk. Nothing that would kill me if I stopped paying attention for a minute. Forklifts and CNC machinery can definitely kill you if you aren't paying attention.
Your weed smoking armorer would probably not be using when working on weapons. His life could be at stake for a loss of concentration, and he knows it. It's smart to avoid weed induced problems, no altruism needed. Just cover your own ass.
Note: I am not strongly committed to this idea I am expressing at the time of this writing. I'm not even sure I am at all committed to it. I do think its a relevant position that seems worth considering, if nothing else.
you'd know this already if you weren't naive
Beyond this, most employment in the US is "at-will", meaning that you can be fired for any reason or no reason. [2]
Some things not explicitly listed as a protected class might still pose problems if its determined that the way in which is it enforced is discriminatory. [3]
