A lot of people will tell you that it doesn't, and I used to agree with them. Until the day I tried to smoke an LFD after lighting it with a Bic. Maybe it was because I was outside and couldn't get it lit very well very quickly, but I DEFINITELY tasted the lighter fluid in that cigar. It was a terrible taste. With that said, if I were indoors and able to light it quickly, I'm not sure I would have tasted it nearly as much. Also, once it's really going, you probably won't taste it anyway.
