What do you know about the chemicals used in cigar manufacturing? We all know there is a ton of different chemicals in cigarettes and as I understand (talking to a buddy that has been smoking cigars for 10+years) most cigar companies (Cuban and Non Cuban) use different levels of additives to keep cigars fresh and enhance flavors. I was told that PG is added to moisten the leaves during the rolling process and it also keeps the cigars fresh Can anyone shed some light on this?
