A strong obsession can easily have a dark side. They can be like a drug addiction and easily take control of your life and put you in the passenger seat, which can be a very scary, helpless and humiliating experience.
I agree that they can become addicting. As a youth, I drove my parents nearly crazy with two of my special topics: fireworks and poisons. I collected them to study and eventually learned how to make my own versions. Even today, fireworks is a dirty word around my mother, as she remembers how much I talked about them endlessly. I did transfer my knowledge of them into my career, so it was not a net loss.
