Use this form to report a figure that does not match its source, an out-of-date page, or a public source worth reading. The editors read every message.

The Quit Ledger is an independent publication. It offers no counselling, no quitline, no clinical service and no personal advice, and it cannot assess symptoms or answer questions about your own medicines. If you need help quitting, speak to a doctor, nurse or pharmacist. If you have symptoms that worry you, contact a clinician or emergency services.

What happens next

Sending the form opens your email program with a message addressed to the editors, so you can read it before it goes. Your address is used only to reply. A confirmed correction is made on the page and its check date changes. How that works is described on the sources and dates page, and the numbers page lists every figure.

The short version

Corrections and source suggestions are welcome. Personal health questions belong with a clinician.
