It's similar but not what I'd call equivalent, because the risks of smoking and vaping are different and differently understood in their respective PR battles.

It's similar but not what I'd call equivalent, because the risks of smoking and vaping are different and differently understood in their respective PR battles. The science is still out on how safe vaping is in the long term, but apart from liquids having certain additives like diethyl that are known to be unsafe now, it appears to be reasonably safe. The undercutting of understanding the risks of cigarettes was happening when the risks would have been blatantly obvious to researchers, unlike with current vaping products. So while the PR technique is similarly appalling, the context is different.
