Source guidance

Definitions of terms used in this quality statement

NICE's guideline on stop smoking interventions and services states that success should be defined by a carbon monoxide monitor reading of less than 10 ppm at 4 weeks after the quit date. This does not imply that treatment should stop at 4 weeks.

Evidence‑based smoking cessation services

These are local services providing accessible, evidence‑based and cost‑effective support to people who want to stop smoking.
