Hello Doug, I believe those little bubbles are "nicotine", and have gotten onto my lips and fingers probably like everyone else from time to time. Some folks say its because of not taking enough time in between puffs (or excessive puffing?), possibly a draw with a smidge of resistance, or as you've mentioned, just a darn right leaf with excessive nutrients. Its occurred to me with a draw that has a smidge of resistance...there may be others with better answers though
