Nearly 49,000 people said they had smoked tobacco in the 28 days before starting treatment. This is based on information collected at the start of treatment and a 6-month review as part of PHE’s treatment outcomes profile (TOP). Across all substance groups, males and females reported smoking at similar levels. And in all cases, the level of smoking was substantially higher than the smoking rate of the general population, 16.4% for males and 12.6% for females. Despite the high levels of smoking, only 3% of people were recorded as having been offered referrals for smoking cessation interventions.
