Like I asked, is safety a concern for EVERY occupation? Sounds like ideology rather than research talking.
Most company’s now have drug free workplace policies. They do this to get lower insurance rates. If a person is taking 4 Vicodin per day [...] Doesn’t matter if they’re a secretary or a laborer, they would not be in compliance.
It woul;dn't be practical (nor, perhaps, legal) for employers or their insurers to have a "drug free only for safety relevant positions" policy. That doesn't mean there aren't people capable of working safely while having a medical condition that requires that much pain medicine.
I deal in the real world. In the real world, there are many many many people taking opioids for chronic pain. They perform their jobs, they go home, crash on the couch or they go to Little League etc. Eventually, the house of cards comes down. The last to go is the job. They’ll show up for the job, even if their wife and kids have left etc.
I see these people before and then after treatment. It’s like night and day.
These are terrible drugs... terrible drugs.
