[quote=live4cigars]Unfortunately there isn’t a lot you can do if the humidity where you are smoking is especially high or low[/quote]
For low humidity, yes there is. Hold the uncut cigar upright under slow-running tap water, turn it around (keeping it vertical!) so all sides of, and locations on, the wrapper get wet, then roll the cigar on a dry towel to absorb the excess. Cut, light, smoke. Helps tremendously in dry-air environments.
Also often improves the cigar in other environments too! Try it.
