According to MSDS safety sheets for
PROPYLENE GLYCOL :
Potential Health Effects
----------------------------------
Inhalation:
No adverse health effects via inhalation.
Ingestion:
Relatively non-toxic. Ingestion of sizable amount (over 100ml) may cause some gastrointestinal upset and temporary central nervous system depression. Effects appear more severe in individuals with kidney problems.
Skin Contact:
Mild irritant and defatting agent, especially on prolonged contact.
Eye Contact:
May cause transitory stinging and tearing.
Chronic Exposure:
Lactic acidosis, stupor and seizures have been reported following chronic ingestion.
Aggravation of Pre-existing Conditions:
Kidney disorders.
My note: The only thing different between nicotine gum, patches, etc. VS. e-cigarettes, is propylene glycol. If the FDA and the medical community support gum, patches, and the like, why not vaping??
Now, on the other hand:
Tobacco smoke contains over 4,000 different chemicals. At least 50 are known carcinogens (cause cancer in humans) and many are poisonous.
Cigarette Chemicals (in Tobacco Smoke)
Benzene (petrol additive)
A colourless cyclic hydrocarbon obtained from coal and petroleum, used as a
solvent in fuel and in chemical manufacture - and contained in cigarette smoke. It is a known
carcinogen and is associated with leukaemia.
Formaldehyde (embalming fluid)
A colourless liquid,
highly poisonous, used to preserve dead bodies - also found in cigarette smoke. Known to cause
cancer, respiratory, skin and gastrointestinal problems.
Ammonia (toilet cleaner)
Used as a flavouring, frees nicotine from tobacco turning it into a gas, found in
dry cleaning fluids.
Acetone (nail polish remover)
Fragrant volatile liquid ketone, used as a
solvent, for example, nail polish remover - found in cigarette smoke.
Tar
Particulate matter
drawn into lungs when you inhale on a lighted cigarette. Once inhaled, smoke condenses and about
70 per cent of the tar in the smoke is
deposited in the smoker's lungs.
Nicotine (insecticide/addictive drug)
One of the
most addictive substances known to man, a powerful and fast-acting medical and non-medical
poison. This is the chemical which causes addiction.
Carbon Monoxide (CO) (car exhaust fumes)
An odourless, tasteless and
poisonous gas, rapidly
fatal in large amounts - it's the same gas that comes out of
car exhausts and is the main gas in cigarette smoke, formed when the cigarette is lit. Others you may recognize are :
Arsenic (rat poison), Hydrogen Cyanide (gas chamber poison)
I think it would be better for one to ingest nicotine and propylene glycol via vaping than the above (plus a few thousand more toxins) noxious chemicals found in analog ciggies....eh?
I, for one, am going to try vaping in an attempt to quit smoking analogs and, in the future, wean myself from the nicotine habit entirely. Now, since I'm entirely new to this e-cigarette thing, I need to find a reliable, reasonably priced source for e-cigarettes! Just got ripped of by SmokingEverywhere...they won't even answer my calls. Never recieved a thing, and am out over a hundred dollars.
