Awful reasoning. You are judging health effects by secondary characteristics, which might be entirely irrelevant. Drinking Tea can make your teeth yellow, that doesn't dictate some latent health risk from having yellow teeth. Or that Tea is worse than snorting coke. What you should be comparing (and are not) is actual health outcomes. Typical stone logic :^)
