Third-hand tobacco smoke exposure and implications for public health. A background paper

The negative health effects of smoking and second-hand smoke (SHS) are well established. However the concept of third-hand tobacco smoke (THS) is an emerging area of interest in public health.

While THS is invisible in contrast to active smoking and SHS, it also leads to involuntary exposure to tobacco smoke products. This background paper provides a brief summary of current evidence relating to THS exposure and its implications for public health.
