Im not against drugs by any stretch of the imagination, and not necessarily against addiction- despite the fact that dependency on anything must limit some aspects of your autonomy.

However! Nicotine itself is specifically not a good drug. In the vast majority of people, myself included, it induces cravings that quickly upgrade your brain's ACh receptors to the point where you no longer experience the enjoyable drug effects, and you're only left with a habit. Technology promises to limit the harm of that habit, which is terrific. But the habit doesn't provide any benefit to the vast majority of people, and technology hasn't made any progress on that front.
