Do you eat sugary foods? Fatty foods? Ingesting sugar and fat causes your brain to release dopamine. Without this mind-altering biochemistry, people wouldn't be nearly as compelled to eat a piece of a chocolate cake or a piece of bacon.
(Note: dopamine reabsorption is also slowed by caffeine, which is why it improves your mood.)
My point is not to be pedantic, it's to say that no matter what you're ingesting, you're altering your mood. While I'd obviously agree that becoming addicted to mood-altering substances isn't a good thing, I think that (like sugar and fat) they can be used responsibly.
