Black sheep from Holts?

Enhancing, dying call it what ever you want. All I know is that your lips shouldn't turn black after smoking a cigar. That's exactly what happened to me the last time I smoked a cigar from Victor Sinclair. I had black stuff on my lips where the cigar was. I didn't realize it until I looked in the mirror and saw it on my mouth. I interacted with several people at that point, they must have wondered what the heck it was.

From my understanding they do it because it's cheaper than properly aging the leaves.
