The same cannot be said for cannabis smoke, which is less studied and chemically distinct from tobacco smoke. That would happen, for example, if a person licked his or her fingers after touching a surface contaminated by cannabis smoke. They then exposed the surfaces to concentrations of ozone that could exist in indoor air. Plenty is known about second- and third-hand smoke (THS) — which are reactive chemicals that remain in the air or are deposited on surfaces like walls, windows, clothing and upholstery, respectively — from tobacco.

Although there’s nothing quite like the stale smell that remains after smoking tobacco, weed smoke also deposits compounds on surfaces that new research suggests can be reduced by ozone, which is found in both indoor and outdoor air.
