Perhaps some influential wine critics do smoke tobacco and don't necessarily want that fact to be widely known. Because they have killed the majority of their taste buds and olfactory receptors, they give higher scores to over-extracted, unbalanced monster wines. That's bad and good news for us non-smokers. Bad, because the top winemakers are making a style of wine that I don't like, in order to get high scores from the tobacco-using wine critics. Good, because the traditionally styled wines with good acidity and reasonable extract and without excessive alcohol, will get lower scores and thus lower prices.
