I live in Colorado and, since the air here maintains almost no humidity, I am concerned for the condition of my snuffs. Is a cigar humidor equipped with a Boveda pack (or an alternative humidity control device) a suitable storage for snuff? Or will this promote cross contamination between aromas, medicated and non-medicated snuffs for example?

Cross contamination would definitely be a worry. Keep mentholated away from non. As far as the humidor goes I’m not sure how much more it would help. Air tight glass jars is what I would recommend. They keep snuff fresh and moist.

if all are in well sealed glass jars, i believe that should be enough. i wouldnt recommend storing too close together unless they are within well sealed glass, as cross-scenting can be an issue.

Thanks to you both! I will purchase a set of glass jars then.
