I'm assuming that's because opiates and alcohol use were widespread, and those are stronger analgesics and anesthetics than cannabis. For anxiety, tobacco was the preferred drug.
That does put a question on the whole modern medical cannabis industry. But of course, cannabis today is much stronger, so who knows? I don't think I could survive an amputation on modern cannabis alone, however. Or even ignore lancing a blister.
It's not an all-or-nothing proposition.
My dad was a cancer patient with severe chronic pain. Cannabis did not eliminate the need for opiates for chronic pain, but reduced the amount of opiates he needed by about half. Using cannabis actually allowed him to be MORE lucid.
Crumbling is not an instant's Act
A fundamental pause
Dilapidation's processes
Are organized Decays —
'Tis first a Cobweb on the Soul
A Cuticle of Dust
A Borer in the Axis
An Elemental Rust —
Ruin is formal — Devil's work
Consecutive and slow —
Fail in an instant, no man did
Slipping — is Crashe's law —
