    Are there any cancers that were found to be “caused by smoking” before 2003?

    Of those, are there any that have subsequently also been found to be “caused by” vaping (such as the tobacco-related ones)?

    If so, then it means vaping is indeed a cause (as opposed to the singular cause) of those cancers even though they were around before vaping was invented (in 2003).

    That’s why this meme is bad.

      If you focus on nicotine specifically, nicotine causes specific type of cancer. Change in the delivery mechanism would cause fluctuations in dosage, but it doesn’t matter in this case (we ignore other types of cancer not to bog down the analogy).
      If one would argue that Tylenol causes autism, two things should be shown, the delivery mechanism of Tylenol before it was invented/isolated, to explain pre-Tylenol cases of autism, and/or specific uptick in autism when it was started to be used as medication.
      It’s possible that the meme is good you just didn’t get it.
