This blog has previously chronicled attempts to scare people into persecuting smokers based on trumped up fears of “thirdhand smoke,” residue left on clothes and furniture after a smoker lights up. New research attempts to measure levels of this residue directly by artificially re-suspending particles left behind by a smoking device:
These quantitative data support the hypothesis of a resuspension from the cigarette smoke surface contamination. However, this airborne contamination through resuspension remains much lower (100 times) than that of secondhand smoke.
In other words, there’s nothing to worry about.
