So you just got the diagnosis: nicotine dependence.

Take a breath. Maybe you've been expecting this for a while, maybe it feels like it came out of nowhere, but either way, it's a real, official diagnosis now, and that word - "dependence" - can hit hard. It sounds serious. It sounds like a judgment. It sounds like something you should have been able to prevent or fix on your own. Let me stop you right there and tell you the most important thing this whole book has to say: this is not a moral failing, and it is not a character flaw. It is a medical condition, and with that diagnosis comes understanding, not guilt.

Let's start with the basics. What exactly is nicotine dependence? In its simplest terms, it's a condition where your brain has physically and chemically adapted to the presence of nicotine, a substance found in tobacco and many e-cigarettes, and it now needs that substance just to feel "normal." Not to feel good - though it can do that, too - but to feel normal. Without it, your brain and your body throw a fit. That fit has a name: withdrawal.
