"...the majority of claims are related to acute exposures and aggravation of a pre-existing medical condition"

Claims about ETS exposure are pertinent to causation/aggravation of disease that is ATTRIBUTED to ETS - not PROVEN to be caused by ETS.

There is a substantial difference between attribution and causality. Stomach ulcers used to be attributed to smoking until it was discovered that they are caused by a virus. It is well known that any means is used to knock the use of tobacco by fanatical groups that seem to have gained control of the state. It is therefore logical that the WCB claims are paid on the basis of ETS causality in order to create the necessary legal bases to implement and augment the repression of public smoking.
