I had two cigarettes on top of my computer desk and the first cigarette I smoked and the second one I had picked up and ran outside to smoke it and when I put it up to my mouth I smelled dog urine (remind you I had the cigarette in my mouth). I smelled my hands thinking that maybe I might of touched something but it wasn't my hands, so I smelled the cigarette and it smelled JUST LIKE DOG URINE! I took it out of my mouth and threw it away, but now I'm not sure if the forst cigarette that I smoked had dog urine on it! If I did, Can it be harmful and do I need to be seen by a doctor or something?
