Thirty-six rabbits received the herbicide, paraquat (1,1'-dimethyl-4,4'-dipyridylium dichloride), by selective intrabronchial instillation in doses ranging from 0.1 gm to 1 pg. Sixteen additional rabbits were given paraquat dichloride (25 mg/kg of body weight) intraperitoneally, subcutaneously, intravenously, or orally. The lung of the rabbit proved to be highly sensitive to paraquat administered by intrabronchial deposition, moderately sensitive to intravenously administered paraquat, and resistant to the chemical when given intraperitoneally or subcutaneously. One picogram of paraquat dichloride delivered by bronchial catheter produced a 1.0-mm pulmonary lesion consisting of focal hemorrhage, congestion of capillaries, intra-alveolar macrophages, and moderate thickening of the alveolar septa. This finding suggests that pulmonary damage could potentially result from smoking marihuana that has been sprayed with paraquat.

Complications resulting from drug abuse more frequently affect the lung than any other organ. The spectrum of pulmonary complications associated with drug abuse is wide. The current practice of using mixtures of drugs is mainly responsible for the increase in pulmonary complications. The chief complications observed in a series of 241 drug abuse patients were aspiration pneumonitis (12.9 percent), pulmonary edema (10.0 percent), and pneumonia (7.5 percent).
