We've managed to get lists of additives that the tobacco companies add to their cigarettes, but what about all the stuff that gets in there by accident? This document from the Brown & Williamson Tobacco Company (B&W) site lists contaminants that contribute to "off-taste" in cigarettes. I haven't seen any documents, though, that discuss the health effects that may arise when customers breathe traces of, for example, pyrolized (burned) pesticides, fungicides, cleaning solvents, printing inks and polystyrene foam ("barn foam").
It isn't much comfort, either, that in discussing the potential for contaminants to get into cigarettes in the manufacturing process, they say:
"...you name it -- it can happen."

QUOTES
OFF FLAVORS -PACKAGING AND PRINTING INKS
Most common source of contamination is from solvent residues from printing inks, lacquers and glues. Polyethylene films - musty, soapy, rancid off-odors... Polypropylene film - irritating off-odor due to 2-(ehtylethio)-propane found in resins Aluminum backed papers - off taste due to preservatives used in glues. Oxidation products of lithography inks - (e.g., rancid, fishy, paint, soapy, green, metallic and fruity off-notes).... Catty (urine) odor - from mesityl oxide used as printing ink & lacquer solvent...
OFF- FLAVORS - FUNGICIDES AND PESTICIDES
Microbial transformations of certain (chlorinated) phenolic materials gives rise to potent "musty" off-taste. One of the most common external sources of off-taste is caused by chlorophenols and chloroanisoles. ...Most common routes of contamination are from wood pallets, cardboard, jute sacks, glue, containers and warehouses. Sources are from microbial transformation of chlorinated fungicides and pesticides and chlorination of phenols in water treatment.
OFF-FLAVORS - OTHER POTENTIAL SOURCES
Pallets/shipping containers/trucks/storage areas - external odor contamination - you name it -- it can happen. ...Barn foam (polystyrene) in flue-cured tobacco A problem for the last few years...
Because of similar bulk density to tobacco it is almost impossible to completely eliminate in processing. Gives "sweetish" taste on pyrolysis in cigarette. Perfume and aftershave
No one handling cigarettes should be allowed to wear perfume of aftershaves containing musks... ...Things like perfumed soap in plant rest rooms are another possible source...
