I'm sorry, this book really doesn't speak to the reasons why I smoked (cognitive stimulation, social connection, a reason to take a break).

I'm glad it's help other people but it feels out-of-touch in exactly the way that I highlighted in my comment above: it demonizes cigarettes, describing the harms of nicotine without the benefits.

In many ways, nicotine is similar to amphetamines or caffeine. Adderall isn't healthy but people take it for a reason. It doesn't help anyone to pretend like it's totally irrational to consume addictive stimulants.
