I purchased my e-cig and vapor juices from I have the JOYE Ego-t with the upgraded battery. This site offeres PG (propoline Glycol) and VG (vegetable Glycerine) juices in many different flavors and nicotine levels. Very fast shipping. This is my first e-cig and I bought it to help me quit smoking. So far I've been doing well, taking a few drags when I have a craving. I've definately cut down the amount I smoke, since I was a pack a day smoker. I've heard a lot of people have problems because they use their e-cigs all the time. They taste good and you can use them anywhere so many people over do it. Your smoking a vapor and those liquid partcles collect in your lungs and if this is done too often, can cause pneumonia (fluid build up in lungs) The key is to use it in moderation and not over do it.

Okay let's get this straight:

Ethylene glycol is the most common type of antifreeze. It is a deadly poison.

Propylene glycol is used in a few brands of antifreeze such as Prestone Low-Tox. It is also used for winterizing water systems in campers, since it is non-toxic. It is also used in foods, cosmetics, and medicines. It is actually an antidote to several poisons such as ethylene glycol. You can buy it by the gallon from a veterinary supply catalog.

Methanol a.k.a. wood alcohol is poisonous. It is occasionally used as a radiator antifreeze, but it is more prone to boil over than ethylene glycol or propylene glycol. It is frequently used as an antifreeze for windshield washer fluid, where boil over isn't a problem.

"Propylene Glycol (Monopropylene Glycol)
Propylene glycol (PG), also called Monopropylene Glycol (MPG) is unique
among glycols in that its very low toxicity permits it to be ingested3. For
applications such as foods, animal feed, pharmaceuticals, cosmetics and
others involving possible ingestion or absorption through the skin, Dow
offers its Propylene Glycol USP/EP (PG USP/EP)4, which is produced and
handled according to current Good Manufacturing Practices (cGMP).

For other industrial and technical uses, Dow offers its Propylene Glycol
Industrial (PGI)5.
In common with the other glycols, PG is odorless and colorless, and has a
wide range of solvency for organic materials, plus it is completely soluble
in water. PG has inherent anti-microbial properties and can be part of an
effective food preservative system.6

Dow’s Propylene Glycol USP/EP is an important solvent in the flavor
concentrate industry, enabling manufacturers to produce low-cost flavor
concentrates of high quality. It is also an excellent wetting agent for natural
gums, greatly simplifying the compounding of citrus and other emulsified
flavors. Dow’s PG USP/EP finds additional use as a solvent in elixirs and
pharmaceutical preparations containing water-soluble ingredients, and
as a solvent and coupling agent in the formulation of sun screen lotion,
shampoos, shaving creams and other similar products. Certain esters of
propylene glycol such as propylene glycol monostearate, are popular as
emulsifiers in cosmetic and pharmaceutical creams.

Dow’s PG USP/EP is an effective humectant, preservative and stabilizer,
and may be used where allowed by local regulations, in such diverse
applications as bakery goods, food flavorings, salad dressings, shave
creams, and semi-moist pet food (with the notable exception of cat food
where propylene glycol use is not approved).7 Humectancy values and
example calculations are presented in another section of this brochure.
For indirect food contact applications, such as brewing and dairy industries
as well as refrigerated display cases, and fluids, Dow recommends its

Dow’s Propylene Glycol Industrial (PGI) is the preferred glycol for use
in high-performance unsaturated polyester resins when manufacturing
reinforced plastic laminates for marine construction, gel coats, sheet
molding compounds (SMC) and synthetic marble castings. It is an important
inter-mediate in the production of alkyd resins for paints and varnishes.
Aqueous solutions of Dow’s PGI display excellent antifreeze properties and
are therefore valuable as low temperature heat-transfer and aircraft and
runway deicing fluids. Dow’s PGI also functions well as a solvent in printing
inks, a solvent and enzyme stabilizer in liquid laundry detergents, and a
stabilizer in hydraulic fluids."

Propylene glycol is indeed automotive antifreeze, although much less common than ethylene glycol. Propylene glycol antifreezes are sold under the brand names Prestone LowTox and Sierra.

Propylene glycol isn't poisonous when ingested until after it is metabolized by the liver. It is digested by the same enzyme that metabolizes ethanol, which is drinking alcohol. The metabolites of propylene glycol are what ultimately cause death. Ethanol has a higher binding affinity to the enzyme than does propylene glycol. Translating the previous to lay terms, ethanol is the antidote for propylene glycol poisoning, but it takes a lot of ethanol. A near fatal dose of ethanol will keep a patient from dying from propylene glycol poisoning if treatment is administered soon enough. Or as I heard a college student say, "Just in case I may have unknowingly ingested antifreeze, I need immediate therapy."

Propylene glycol is used:

As an ingredient in the oil dispersant Corexit, used in great quantities during the Deepwater Horizon oil spill.[5][6]
As a solvent in many pharmaceuticals, including oral, injectable and topical formulations. Notably, diazepam, which is insoluble in water, uses propylene glycol as its solvent in its clinical, injectable form.[7]
As a humectant food additive, labeled as E number E1520
As an emulsification agent in Angostura and orange bitters
As a moisturizer in medicines, cosmetics, food, toothpaste, shampoo, mouth wash, hair care and tobacco products
As a carrier in fragrance oil
To produce polyester compounds
As a base in deicing solution
As an ingredient in massage oils
In hand sanitizers, antibacterial lotions, and saline solutions
In smoke machines to make artificial smoke for use in firefighters' training and theatrical productions
In electronic cigarettes, as a vaporizable base for diluting the nicotine liquid
As a solvent for food colors and flavorings
As an ingredient, along with wax and gelatin, in the production of paintballs
As a moisture stabilizer (humectant) for snus (Swedish style snuff).
As a cooling agent for beer and wine glycol jacketed fermentation tanks
As a non-toxic antifreeze for winterizing drinking water systems, and in applications where the used antifreeze eventually will be drained into the soil, water, or a septic system.[8]
As a less-toxic antifreeze in solar water heating systems
As a solvent used in mixing photographic chemicals, such as film developers
In cryonics
As a working fluid in hydraulic presses
As a coolant in liquid cooling systems
To regulate humidity in a cigar humidor
As the killing and preserving agent in pitfall traps, usually used to capture ground beetles
As an additive to pipe tobacco to prevent dehydration.
To treat livestock ketosis
As the main ingredient in deodorant sticks.
To de-ice aircraft.[9]
As an ingredient in UV or blacklight tattoo ink
As a lubricant in air conditioning compressors.
As a wetting agent, used to determine drying time in paints and coatings

Propylene glycol has properties similar to those of ethylene glycol (monoethylene glycol, or MEG). (Note: Infrequently propylene glycol may also use the acronym MEG, but as an abbreviation of methyl ethyl glycol- the industry standard acronym for propylene glycol is PG or MPG (monopropylene glycol)). The industrial norm is to replace ethylene glycol with propylene glycol when safer properties are desired.

What I suggest is make sure the product is USP grade. USP means the products has been certified for use in food. Ref site: [url][/url]. If you can get a kosher product (which a U enclosed with a circle) that is a bonus. This means the product was viewed by a a rabii of the orthodox church and the product was not packaged in someones garage. I read this at [url][/url]. You can also try Glycerin at [url][/url].

Pro smoke does not use PG, however, the do not make juice. Have to buy the whole package. Good tasting product.

Propylene Glycol is not Antifreeze. good grief

Yes it is food grade antifreeze! check wikipedia!
