What do those have to do with anything? A patient coming to a doctor looking for answers to what they’re struggling with does not mean they’re faking. The opioid epidemic was caused by doctors and pharmaceutical companies underplaying the addiction risks for far too long. That has nothing to do with patients who can’t get diagnosed. Pain is a common symptom of many diseases, but having pain doesn’t mean drug seeking. And if you’d bother to read anything (because clearly you’re not) you’d see that doctors are not prescribing pain medications when not warranted based on the presenting complaint to a huge extent, and that is even more true in todays world where they’re even going after pharmacies for not controlling opioid medications better and verifying abuse. Trying to discuss opioids in this context isn’t even the same thing.

And medical marijuana? What does that have to do with anything. You seem to be making an assumption that the people who are going undiagnosed are walking away with either an opioid prescription or using medical marijuana with zero data to support it. Stop distracting from the fact that you are absolutely wrong in your baseless assumption people who are undiagnosed after visiting a primary doctor are faking.
