It took the Federal Court "5" years to reach their conclusion, after much research from medical sources helping the court.
And with exactly how much protest from the tobacco industry? I would like the names of these "medical sources" that directed the court as such with their "research".
As I see it, it took time before Bubba Clinton and his anti-smoking crowd were replaced with a more tolerant administration. The report you cited was generated under Bubba and thusly was tilted. Again, Federal Court rulings aren't without error - they'd have done the same if the report were overly whitewashed in smoking's favor.
