Plicatic and abietic acids from cedar and pine resin cause direct damage to human epithelial cells and chronic exposure can lead to either occupational asthma or (if the worker's response is worse) can lead to pulmonary fibrosis. Woodworker's lung is the name for the fibrosis associated with the chronic inhalation of pine or cedar dust.

Abietic acid is found in colophony, a derivative of pine trees also called rosin. Colophony has a number of industrial applications including solder fluxes, paper sizing, adhesives, paints, varnishes, printing inks, and plasticizers. Colophony is a major occupational health hazard and is the third highest cause of occupational asthma.Western red cedar and eastern white cedar can cause asthma.
