Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable chest radiograph demonstrates unremarkable mediastinal contours . There is stable mildly enlarged cardiac silhouette . There has been interval increase in diffuse alveolar opacities with a basilar predomince , left greater than right with loss of left hemidiaphragm silhouette . Given multiple prior studies demonstrating rapid increase and decrease of opacification and previously provided history of cocaine use , findings suggest acute non-cardiac pulmonary edema versus pulmonary toxicity .
    OUTPUT:
    
Increased asymmetric predominantly basilar diffuse airspace opacifications likely represent acute non-cardiac edema vs pulmonary toxicity from inhaled substance .
