As someones whos family has a history of addiction and who strongly believes in moderation for everything this was an interesting read. I saw a lot of reviews complaining that the author used porn and romance novels heavily as reference points and I feel like those people arent quite understanding what the book is saying. It doesnt say everything that creates pleasure/dopamine is inherently bad for everyone but that everything is bad when done in excess. For some thats reading romance novels, for another its porn, for another its weed... everything is addictive if we let it. When we only do that thing to chase the dopamine it gives us then its no longer just an enjoyable thing but an addiction.
