>Nicotine addiction is a terrible enslavement.

The interesting part I think is that physical nicotine addiction only lasts two weeks. It's the smoking ritual that is so potent. I have several ex-smokers in my family who even after decades still have situations where they associate certain cues with smoking.

Honestly, the mental aspect of addiction is what makes it difficult. Anyone can get through a couple of weeks feeling like shit, especially if you have support. But for years and years, you can be addicted to something that never even entered your body.
