Yes, the scent can linger depending on ventilation and the concentration of vapor released
As the aerosol evolves from its formation into the respiratory tracts, there is no longer heat supply, hence only phase changes that modify the phase partition and droplet sizes through other physical aerosol processes whose effects depend on particle sizes and chemical composition (coagulation, nucleation, impaction, gravitational settling, diffusion)
"People who smoke are more likely to have deterioration in gray and white matter, which provides a possible explanation as to why 14% of global Alzheimers disease cases could be attributable to cigarette smoking," they wrote in the study findings
