As smoking? Well one nutrition Regal Keto scientist replied that it would be potentially dangerous to compare the effects of smoking with the effects meat and cheese Why? Because a smoker might think "why bother quitting smoking if my ham and cheese sandwich is just as bad for me" So better not to tell anybody about the whole meat and dairy thing This reminds me of a famous Philip Morris ad a cigarette ad that tried to downplay the risk by saying look you think secondhand.
