I used to think so, too. But I've learned it's more complicated than that. There are choices in the beginning, often poor choices, but they are not choices to become an addict. And once addicted, it takes more than just "will power" to overcome it. There is a book, The Molecule of More, about dopamine that helped me get a better understanding of addiction. It is informative and engaging and well worth reading.

So it is a choice?
