THC liquid extract can fit anywhere, so cannabis oil vaporizers do not have to be as large as dry herb devices. In longer 2-week inhalation studies in rats, researchers from the National Institute of Environmental Health Sciences (NIEHS) found that repeated exposures to either 2,3-pentanedione or diacetyl can cause airway fibrosis, including obliterative bronchiolitis-like changes, in rats (Morgan et al. Similarly, diacetyl can cause changes in gene expression and other markers of damage in the olfactory bulb of the mouse brain (Hubbs et al. Furthermore, diacetyl reacts with proteins and a recent study demonstrating striking changes in protein homeostasis in the airways of diacetyl-exposed mice strongly implicates protein damage in airway epithelium as the mechanism for diacetyl-induced airway injury (Hubbs et al. Thus, NIOSH’s initial studies in a total of six microwave popcorn plants were not able to definitely determine if diacetyl exposure contributed to lung disease or was a marker for other hazardous substances that contributed to disease.
