Oh, no. It very much depends on the person. You have to take a holistic view. People who live long while smoking may have other habits that are healthy. Or it might be partially genetic. Or luck. Some associate lower caloric intake with long life, at least, in fruit flies. Perhaps that's all it was. Maybe he just consumed fewer calories than average. And while alcohol is a carcinogin, there are things in some drinks that are anti-cancer. Then again, I know a long term smoker/drinker who died in a fire from his drunken smoking. His lungs were actually pretty clean given his long term smoking. And yet he died from drinking and smoking nonetheless.
And consensus is often just a majority of people who are wrong. I would endeavor to say most voters were wrong in quite a few elections. I won't say which, and I bet you might agree with me in principle. Consensus does not equal the truth. (I still think Democracy is the best system though anyway btw.)
Random example of silly consensus:
This was once an effective political ad. I bet a consensus of "Citizens for Eisenhower" loved and endorsed it. And a majority of voters voted for Ike. And yet people would laugh at you if you tried such an ad today. They would laugh the politician out of the election. OR they would think it was just a bad SNL animation.
And consensus is a fleeting thing. I am only after the truth. Sure my personal examples may not effect you the way they effected me. You don't know the people personally.
Here have just one link that associates cancer with cell phone use:

Salivary gland
Last month, a study in the American Journal of Epidemiology, suggests that cell phone use contributes to at least some cancers.
The study found focused on cancer of the salivary gland, looking at 500 Israeli citizens who had developed the disease and 1,300 healthy subjects.
Researchers concluded that those who had held a mobile handset against one side of their head for several hours a day were 50 percent more likely to have a tumor in the salivary gland."
Oh, and aspartame is slowly being viewed more and more negatively, even though they used to think it was safe.
Some say aspirin would not make it to market if it was discovered and released today, given it's danger.
So to sum up. You have to review the evidence you see yourself and make up your own mind.
