My understanding is that the "states" sued the tobacco companies to recover the medical costs (damages) of treating smokers.
*nudge nudge wink wink*
That makes requiring actual damages even less of an issue.
If the states paid it was through Medicare Medicaid, so they had already received the funds to run it. They had no added financial burden because of tobacco because any tobacco problem was already there and factored in.
Plus that lumps all those "smoking diseases" that aren't caused by smoking into it without proof of those actual damages.
Here's the Wiki run down of the settlement.
Tobacco Master Settlement Agreement - Wikipedia, the free encyclopedia
"The states settled their Medicaid lawsuits against the tobacco industry for recovery of their tobacco-related health-care costs, and also exempted the companies from private tort liability regarding harm caused by tobacco use."
Got the actual damage? Sorry, you get nothing. Got unprovable financial damage that is simply claimed to be cause by smokers that you may or may not actually pay for? Sure, you can have the money.
Go down and see what Godshall has to say about it. It's protection money. Pay the government to protect you from liability.
The problem is they passed it off as legal precedence. So do we really need actual damages or can we get away with what the government had and just allege there could be possible damages?
The same with second hand smoke. There is no proof that it is harmful yet governments are passing laws to ban it for people's "safety". That makes it pretty hard for them to ignore forcing non-smokers into smoking areas as harmless until damages are proven.
