Good afternoon friends, I have a question that perhaps some of you can shed some light on. I read once upon a time that some cheaper aromatics contain things like propylene glycol as a humicant. My knowledge of chemistry would tell me that something like that would combust to form formaldehyde or acetylaldehyde... which are obviously not good things. One is used to embalm bodies, and one is the chemical that largely contributes to a hangover. Is this statement true? The only aromatics I buy are house blends from a very reputable pipe shop so I highly doubt they're putting any gunk in their leaf. I'm just curious if anyone else has heard of this/ if there are any tobaccos known to have chemical additives in them. I'd like to steer clear of those if they're out there. Thanks!
