The Quit Ledger

KeysKeys 1 to 5 are the stages of a quit. The sigma key opens the table of every figure.

Every figure on this site, with its source

One table of the headline figure from each topic page, linked to the publisher page the editors opened.

Updated 11 October 2026By the editors

This page gathers the headline figure from each topic page in one place. The table is generated from the pages themselves, so it cannot drift from them: if a figure changes on a topic page, it changes here. Every row names the publisher and links to the page that was opened.

How to read the table

The figure is exactly as the source states it, in the units the source uses. The year column is the year of the data or the page, not the year of this check. A survey figure describes the people surveyed, which may be adults in one country, so read the sentence next to each figure for who it covers. The rules for finding and dating figures are on the sources and dates page.

Before you rely on a figure

A population figure says little about any one person. Whether a particular medicine, product or approach is suitable depends on health, other medicines and circumstances, so questions of that kind belong with a doctor, nurse or pharmacist. To see how the evidence for each approach compares, start with quit methods compared, and for the pattern of recovery see what happens to the body after you quit.

The short version

One row per topic, one source per row, every link going to a publisher page the editors opened.
