Check these ingredients...safe???

So when I run out of supplies that I need to order online, I often go down to the 7-11 and pick up a 3-pack of Metro cartomizers. Has anyone used these? They taste pretty decent, actually. Anyways, I was perusing their website, and they list all the ingredients in these, but they seem kind of crazy to me. They are as follows -

Is it safe to use METRO? What ingredients are in them?

The primary cartridge ingredient is propylene glycol, and the secondary ingredients are water, nicotine and a flavor to replicate the taste of traditional smoking. There are much less ingredients in a METRO than a traditional cigarette.

• Propylene Glycol - The Food and Drug Administration (FDA) has determined propylene glycol to be "generally recognized as safe" for use in food and propylene glycol is used in cosmetics and medicines. It is used in food coloring, and flavoring, as an additive to keep food, medicines and cosmetics moist, and in machines that simulate smoke, although usage in simulating smoking devices is not currently included in the list of uses recognized by the FDA. In METRO, propylene glycol functions to provide the vapor mist that looks like smoke and to suspend flavor
• Water - The water used in METRO cartridges is filtered via a reverse-osmosis process
• Nicotine - is an alkaloid found in certain plants, predominately tobacco, and in lower quantities, tomatoes, potatoes, eggplants, cauliflower, bell-peppers and some teas.
• Ethanol - is 200% proof alcohol (same as used in making alcoholic beverages) and is used to extract nicotine from the tobacco leaf.
• Glycerol (glycerin) - Glycerol is a chemical compound also commonly called glycerin or glycerine. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. For human consumption, glycerol is classified by the FDA among the sugar alcohols as a caloric macronutrient.
• Acetylpyrazine - Used in the creation and/or manufacturing of cocoa, coffee, roasted peanuts, tea, beer, breakfast cereals, ice cream, candy, and other food products and nicotine cartridges and has been deemed safe for use by people.
• Guaiacol - is an ingredient use to give the smoky taste.
• Myosmine- is found in nut products, as well as tobacco
• Cotinine- is metabolite of nicotine. Some studies have suggested that cotinine (as well as nicotine) improves memory and prevents neuron death
• Vanillin- is used in the food industry as a flavoring agent in foods, beverages and pharmaceuticals.

Can someone with some knowledge about these kinda things take a look at this and give me their opinion? Wondering if these are still safe to use.

That is actually a better ingredient list than most juice manufacturers have. The stuff I usually see is VG, PG, flavoring, and nicotine. Some say organic flavoring, some say food grade, and some say nothing. Most of the strange stuff you have is probably stuff they use to flavor it.

I would think it's as safe or safer than most of the stuff I stick in my mouth.

Of course I only play a medical researcher. ;-}
