That's the effect on brain chemistry I referred to.
Do you actually enjoy the smoke in your mouth, burning your eyes and lungs?
A cold beer on a hot day is refreshing just for its temperature alone. A fruity cocktail tastes good because sugar tastes good. What's enjoyable about the physical sensations produced by smoke?
I mean maybe we're arguing semantics, because the pleasure of eating sugar is possibly also an alteration of brain chemistry. But there is a difference.
