lol.

My GF absolutely LOVES peeps. But only if they are stale on the outside. So she gets them (I give her some every Easter) and then she opens the pack and lets them sit for a few days. IDK why. Makes zero sense to me, but if she likes that cool.

Stepson gets a box of peeps, pokes holes in the plastic and lets set. I can't remember the last time I ate a peep; nothing against them, just, meh.

Eeeek! :shock:

Chocolate threats: Carcinogenic PAHs - Ezine - spectroscopyNOW.com

While children around the world are digging into their cache of Easter eggs, scientists are concerned about the amounts of carcinogenic polycyclic aromatic hydrocarbons that the treats might be harbouring. It is well known that cocoa butter contains higher levels of PAHs than other types of oils and fats as a result of poorer refining during processing and inadequate drying practices. They find their way into foods and sweets containing chocolate and contribute to the overall exposure of an individual. At particular risk are children, who tend to eat more chocolate than adults and have a lower safe threshold.

The European Food Safety Authority recently recognised that its criteria for detecting PAHs in food were deficient. They relied on the occurrence of a single PAH, benzo[a]pyrene, as a marker of PAHs but they have recently agreed to expand this to a panel of four PAHs from April 2013 in order to protect consumers.

OK Catt. Point made. The guy is way off base. lol.

Although you can argue that petroleum (from which comes the asphalt tar...I think) is oxidized/processed plant material.

Not that I'm about to argue with a chemist on that point at all. But I wonder how much ends up similar....

Fire = fast oxidation of plant material and hydrocarbons.
Oil = slow oxidation (and whatever) of plant hydrocarbons.

So ???????????

OTOH...maybe oil is anaerobic processing of the plant material and not really oxidized. IDK. Probably completely different chemically.

Wish we knew a chemist that we could ask about it...particularly one that vapes...and then see how far off base the guy really is.

.......................????????? ;)

(Since you brought it up)

So is it just a Wive's Tale? Or is there some validity?

In this area, you can be as knowledgeable as me Atty :D.

Wiki:
The substance is completely soluble in carbon disulfide, and composed primarily of a mixture of highly condensed polycyclic aromatic hydrocarbons; it is most commonly modelled as a colloid, with asphaltenes as the dispersed phase and maltenes as the continuous phase (though there is some disagreement amongst chemists regarding its structure). One writer stated although a "considerable amount of work has been done on the composition of asphalt, it is exceedingly difficult to separate individual hydrocarbon in pure form",[10] and "it is almost impossible to separate and identify all the different molecules of asphalt, because the number of molecules with different chemical structure is extremely large".[11]
Most natural bitumens contain sulfur and several heavy metals, such as nickel, vanadium, lead, chromium, mercury, arsenic, selenium, and other toxic elements.[citation needed] Bitumens can provide good preservation of plants and animal fossils.
Asphalt/bitumen can sometimes be confused with "tar", which is a similar black, thermoplastic material produced by the destructive distillation of coal. During the early and mid-20th century when town gas was produced, tar was a readily available product and extensively used as the binder for road aggregates. The addition of tar to macadam roads led to the word tarmac, which is now used in common parlance to refer to road-making materials.

Don't think you get the same thing from just burning tobacco. Cigarette "tar" is called this by the physical resemblance; although there may be some common constituents in "tar" and tar. ;)
