The urge to run is overwhelming. The poisonous gas engulfs me, it seeps into my clothes, and it chokes me. I can feel the years of my life slipping away. I pick up the speed of my gait, and bolt out of the first open door, into the hot night air. I breathe deeply, relieved to be out of the nightclub and the thick, toxic, fog of smoke. The open air relieves my nausea and the lightheaded feeling, caused by the strangling secondhand smoke.
