I've been reading 📙 The Biology of Desire, a fascinating book about Addiction by Marc Lewis, who became a professor of neuroscience as he himself was recovering from a decade of compulsive drug use. He, like many others, challenges the "brain disease model" of addiction, describing addiction instead as an especially potent and harmful instance of the same processes of desire-driven learning that is normally adaptive and integral to finding safety, happiness, and well-being.
