eduardo agreed that smoking causes cancer with the proviso that it doesn't always do so and then gave 2 instances where (unspecified) consequences would definitely follow from causes.
Eduardo did not do that, which is the point here.
Firstly, eduardo didn't even give cause and effect, but if we assume the effect is death then certainly that does not "definitely follow" from falling under a bus or falling from a ladder.
No more so than a cancerous cell results from activation of an oncogene.
The main distinguishing feature of Eduardo examples is that they are quick and visible, not that there is any more or less of a causal connection.
THommo made the point well:

Nonetheless cells with activated oncogenes and no blood supply don't cause cancer. Other conditions also must be present or absent.
That is true. It was what I was saying that there is no clear cause for cancer.
It is not simple like falling under a bus or off a ladder.
A fairer comparison might be, from general to more specific :
Smoking kills <--> traffic kills <--> Working at height is dangerous
Smoking causes cancer (etc) <--> Vehicles contribute to collisions with pedestrians (pollution etc)<--> Working at height causes high energy ground impacts
Cancer causes physical trauma <--> vehicles cause physical trauma <--> ground impact causes physical trauma
In each case some failure of essential biological processs causes death
Cancer, and other diseases caused by smoking, cause the damage on a longer timescale and are less visible, but why would that be less causal than a faster process?
It's pretty much arbitrary what you focus on and what you leave out. "falling under a bus" leaves out almost everything.
