Kate, I'm missing and having Al Bundy withdrawls, maybe we should call him in?
Lucky--Come on--thinks could not be that bad to what the "number clown" back---Sun
Oh but he was so entertaining for a day. No?
The thing with him was I really think he believed what he was saying--and that is scary---LOL---Sun
Yes, it was intense to say the least. I think Kate knows about as much as anyone about this stuff. She's amazing, and oh so patient with people. Hats off to Kate!!!
Dan! What did I miss? See what happens when I have a girls night....I miss the good stuff
Dan! What did I miss? See what happens when I have a girls night....I miss the good stuff
OMG you don't even want to know. You'll get a migraine reading it. LOL
There is some good info below on acrolein but the part that really reassured me about using VG was this:
Acrolein is a clear, colorless, or yellow liquid with a pungent, suffocating odor. It is very flammable and may polymerize violently.
So if your liquid starts to smell really bad watch out for the fire/explosion and stop vaping it. You will then know what that big gooey lump is on your atomiser! Other symptoms are listed which would warn us of any potential danger.
Has anyone suffered any of these symptoms with VG and not with PG? Many people report dry throats etc but that is probably down to the inherent properties of PG/VG, they are humectants that help to stop food drying out by absorbing moisture, which is why you need to keep your fluid levels up when vaping.
There should be some radical VG liquid on the market in the UK in a few weeks but I am sworn to secrecy!

Medical Management Guidelines
for
Acrolein
(C3H4O)
Synonyms include 2-propenal, 2-propen-1-one, prop-2-en-1-al, acraldehyde, acrylaldehyde, acrylic aldehyde, allyl aldehyde, ethylene aldehyde, aqualine.
- Persons exposed only to acrolein vapor do not pose secondary contamination risks. Persons whose clothing or skin is contaminated with liquid acrolein can secondarily contaminate others by direct contact or off-gassing vapor.
- At room temperature, acrolein is a clear, colorless to straw-colored liquid with a pungent, suffocating odor. It is highly flammable and burns to produce toxic gases (peroxides and oxides of carbon). It is volatile, producing toxic concentrations at room temperature. Vapors may travel to a source of ignition and flash back. The odor of acrolein may not provide adequate warning of hazardous concentrations.
- Acrolein is toxic by all exposure routes. Exposure causes inflammation and irritation of the skin, respiratory tract, and mucous membranes. Delayed pulmonary edema may occur after inhalation. Systemic effects may occur after exposure by any route.

Description
Acrolein is a clear, colorless, or yellow liquid with a pungent, suffocating odor. It is very flammable and may polymerize violently. Acrolein should be stored in a cool, dry, well-ventilated area in tightly sealed containers separated from alkaline materials such as caustics, ammonia, organic amines, or mineral acids, strong oxidizers, and oxygen. Acrolein is soluble in water, alcohol, ether, and acetone.
Routes of Exposure
Inhalation
Inhaled acrolein is highly toxic. Acrolein is irritating to the upper respiratory tract even at low concentrations. Its odor threshold of 0.16 ppm is similar to the OSHA permissible exposure limit (0.1 ppm); thus odor may provide an adequate warning of potentially hazardous concentrations. Acrolein vapor is heavier than air, but asphyxiation in enclosed, poorly ventilated, or low-lying areas is unlikely due to its strong odor.
Children exposed to the same levels of acrolein vapor as adults may receive a larger dose because they have greater lung surface area:body weight ratios and higher minute volumes:weight ratios. In addition, they may be exposed to higher levels than adults in the same location because of their short stature and the higher levels of acrolein vapor found nearer to the ground.
Skin/Eye Contact
Direct contact with liquid acrolein causes rapid and severe eye and skin irritation or burns. Exposure to vapor produces inflammation of mucous membranes and it is a potent lacrimator.
Because of their relatively larger surface area:body weight ratio, children are more vulnerable to toxicants affecting the skin.
Ingestion
Acrolein produces chemical burns of the lips, mouth, throat, esophagus, and stomach. Nausea, vomiting, and ........ also occur.
Sources/Uses
Acrolein is produced by oxidation of propylene.
Acrolein is principally used as a biocide to control plants, algae, molluscs, fungi, rodents, and microorganisms. Acrolein has also been used in the manufacture of other chemicals, as a warning agent in gases, as a test gas for gas masks, in military poison gases, in the manufacture of colloidal metals, in leather tanning, and as a fixative in histology.
Standards and Guidelines
OSHA PEL (permissible exposure limit) = 0.1 ppm as an 8-hr TWA concentration and 0.3 ppm as a 15-minute TWA short-term exposure limit (STEL).
NIOSH IDLH (immediately dangerous to life or health) = 2 ppm.
AIHA ERPG-2 (maximum airborne concentration below which it is believed that nearly all persons could be exposed for up to 1 hour without experiencing or developing irreversible or other serious health effects or symptoms that could impair their abilities to take protective action) = 0.5 ppm.

Health Effects
- Acrolein is severely irritating to skin, eyes, and mucous membranes. Inhalation of acrolein may result in respiratory distress and delayed pulmonary edema. Contact with the skin or eyes produces irritation and lacrimation, and can result in chemical burns.
- The mechanism by which acrolein produces toxic symptoms is not known, but the compound is highly reactive. No information was found as to whether the health effects of acrolein in children are different than in adults. Exposure to acrolein produces severe respiratory problems and individuals with pre-existing breathing difficulties or skin disease may be more susceptible to its effects.
The mechanism by which acrolein produces toxic symptoms is not known, but the compound is highly reactive, cross-links DNA, and inhibits the activities of some enzymes (including cytochrome P450 and glutathione-S-transferase) in vitro by reacting with sulfhydryl groups at the active sites. It has also been shown to suppress pulmonary antibacterial defenses, to release oxygen radicals, and to react with proteins. Onset of irritation is immediate, but pulmonary edema may be delayed and respiratory insufficiency may persist for up to 18 months after exposure.
Children do not always respond to chemicals in the same way that adults do. Different protocols for managing their care may be needed.
Respiratory
Acrolein produces irritation of the respiratory tract, increases airway resistance and tidal volume, and decreases respiratory frequency. It is also ciliastatic. Exposure to acrolein vapor concentrations as low as 10 ppm can lead to pulmonary edema and death. Inhalation may also cause an asthmatic reaction in sensitized individuals.
Acrolein is a weak sensitizer.
Children may be more vulnerable because of higher minute ventilation per kg and failure to evacuate an area promptly when exposed.
Dermal
Acrolein is a skin irritant. Contact with the liquid may cause skin burns, erythema, and edema.
Because of their relatively larger surface area: body weight ratio, children are more vulnerable to toxicants affecting the skin.
Ocular/Ophthalmic
Acrolein liquid or vapor can cause eye irritation and damage to the cornea.
Gastrointestinal
Acrolein causes burns of the lips, mouth, throat, esophagus, and stomach. Nausea, vomiting, and ........ have been reported. No data were located as to whether ingestion leads to systemic toxicity in humans.
Cardiovascular
Acrolein inhalation may cause hypertension and tachycardia.
CNS
Serious poisoning may cause CNS depression.
Immunologic
Acrolein may have the potential to be immunotoxic.
The immune system in children continues to develop after birth, and thus children may be more susceptible to certain chemicals.
Potential Sequelae
Respiratory insufficiency may persist for up to 18 months after exposure.
Chronic Exposure
Apart from rare cases of sensitization, no adverse effects in humans chronically exposed to low concentrations of acrolein have been reported.
Chronic exposure may be more serious for children because of their potential for a longer latency period.
Carcinogenicity
The Department of Health and Human Services has determined that acrolein may possibly be a human carcinogen. The International Agency for Research on Cancer has determined that acrolein is not classifiable as to its carcinogenicity to humans.
Reproductive and Developmental Effects
No studies were located that address reproductive or developmental effects of acrolein in humans. Acrolein caused developmental effects when injected into rats, but did not cause developmental effects when ingested by rabbits. No information was found as to whether acrolein crosses the placenta, but it has been measured in breast milk.
Acrolein is not included in Reproductive and Developmental Toxicants, a 1991 report published by the U.S. General Accounting Office (GAO) that lists 30 chemicals of concern because of widely acknowledged reproductive and developmental consequences.

Prehospital Management
- Victims exposed only to acrolein vapor do not pose contamination risks to rescuers. Victims whose clothing or skin is contaminated with liquid acrolein can secondarily contaminate response personnel by direct contact or by off-gassing vapor.
- Acrolein is a direct irritant to mucous membranes, skin, eyes, and the respiratory system. Acute inhalation exposure may lead to respiratory distress and noncardiogenic pulmonary edema.
- There is no antidote for acrolein. Treatment consists of respiratory and cardiovascular support.
Rescuers should be trained and appropriately attired before entering the Hot Zone. If the proper equipment is not available, or if rescuers have not been trained in its use, assistance should be obtained from a local or regional HAZMAT team or other properly equipped response organization.
Rescuer Protection
Acrolein is highly toxic via all routes and is severely irritating to the eyes, mucous membranes, respiratory tract, and skin. Acrolein is highly flammable, can form explosive mixtures with air, and burns to produce irritating, corrosive and/or toxic gases. Acrolein vapor may travel to a source of ignition and flash back.
Respiratory Protection: Positive-pressure, self-contained breathing apparatus (SCBA) is recommended in response situations that involve exposure to potentially unsafe levels of acrolein.
Skin Protection: Chemical-protective clothing is recommended because acrolein can cause skin irritation, burns, and sensitization. Fully encapsulating, vapor protective clothing should be worn to deal with spills or leaks with no fire.
ABC Reminders
Quickly establish a patent airway, ensure adequate respiration and pulse. If trauma is suspected, maintain cervical immobilization manually and apply a cervical collar and a backboard when feasible.
Victim Removal
If victims can walk, lead them out of the Hot Zone to the Decontamination Zone. Victims who are unable to walk may be removed on backboards or gurneys; if these are not available, carefully carry or drag victims to safety.
Consider appropriate management of anxiety in victims with chemically-induced acute disorders, especially children who may suffer separation anxiety if separated from a parent or other adult.
Decontamination Zone
Patients exposed only to acrolein vapor who have no skin or eye irritation may be transferred immediately to the Support Zone. Other patients will require decontamination as described below.
Rescuer Protection
If exposure levels are determined to be safe, decontamination may be conducted by personnel wearing a lower level of protection than that worn in the Hot Zone (described above).
ABC Reminders
Quickly establish a patent airway, ensure adequate respiration and pulse. Stabilize the cervical spine with a collar and a backboard if trauma is suspected. Administer supplemental oxygen as required. Assist ventilation with a bag-valve-mask device if necessary.
Basic Decontamination
Victims who are able may assist with their own decontamination. Quickly remove and double-bag contaminated clothing and personal belongings.
Flush exposed skin and hair with copious amounts of water. Wash with soap and rinse thoroughly with water. Use caution to avoid hypothermia when decontaminating victims, particularly children or the elderly. Use blankets or warmers after decontamination as needed.
Flush exposed or irritated eyes with tepid water for 15 minutes. Remove contact lenses if easily removable without additional trauma to the eye. Continue eye irrigation during other basic care and transport. If pain or injury is evident, continue irrigation while transferring the victim to the Support Zone.
In cases of ingestion, do not induce emesis. If the victim is alert, asymptomatic, and has a gag reflex, administer a slurry of activated charcoal at a dose of 1 g/kg (infant, child, and adult dose). A soda can and a straw may be of assistance when offering charcoal to a child.
Victims who are conscious and able to swallow should be given 4 to 8 ounces of milk or water (not to exceed 15 mL/kg in a child). If the victim is symptomatic, delay decontamination until other emergency measures have been instituted.
Consider appropriate management of chemically contaminated children at the exposure site. Provide reassurance to the child during decontamination, especially if separation from a parent occurs.
Transfer to Support Zone
As soon as basic decontamination is complete, move the victim to the Support Zone.
Support Zone
Be certain that victims have been decontaminated properly (see Decontamination Zone, above). Victims who have undergone decontamination or have been exposed only to vapor pose no serious risks of secondary contamination to rescuers. In such cases, Support Zone personnel require no specialized protective gear.
ABC Reminders
Quickly establish a patent airway, ensure adequate respiration and pulse. If trauma is suspected, maintain cervical immobilization manually and apply a cervical collar and a backboard when feasible. Administer supplemental oxygen as required and establish intravenous access if necessary. Place on a cardiac monitor.
Additional Decontamination
Continue irrigating exposed skin and eyes, as appropriate.
In cases of ingestion, do not induce emesis. If the victim is alert, asymptomatic, and has a gag reflex, administer a slurry of activated charcoal at a dose of 1 g/kg (infant, child, and adult dose) if it has not already been administered. A soda can and a straw may be of assistance when offering charcoal to a child.
Victims who are conscious and able to swallow should be given 4 to 8 ounces of milk or water (not to exceed 15 mL/kg in a child) if it has not been given previously. If the victim is symptomatic, delay decontamination until other emergency measures have been instituted.
Advanced Treatment
In cases of respiratory compromise, secure airway and respiration via endotracheal intubation. If not possible, perform cricothyrotomy if equipped and trained to do so.
Treat patients who have bronchospasm with an aerosolized bronchodilator such as albuterol. Consider that acrolein inhalation may cause hypertension and tachycardia, in which case the use of bronchodilators that are known cardiac sensitizing agents may pose enhanced risk. Administer corticosteroids as indicated to patients who have persistent wheezing or hypersensitivity pneumonitis.
Consider racemic epinephrine aerosol for children who develop stridor. Dose 0.25-0.75 mL of 2.25% racemic epinephrine solution; repeat every 20 minutes as needed, cautioning for myocardial variability.
Patients who are comatose, hypotensive, or having seizures or cardiac arrhythmias should be treated according to advanced life support (ALS) protocols.
If evidence of shock or hypotension is observed, begin fluid administration. For adults with systolic pressure less than 80 mm Hg, bolus perfusion of 1,000 mL/hour intravenous saline or lactated Ringer's solution may be appropriate. Higher adult systolic pressures may necessitate lower perfusion rates. For children with compromised perfusion, administer a 20 mL/kg bolus of normal saline over 10 to 20 minutes, then infuse at 2 to 3 mL/kg/hour.
Transport to Medical Facility
Only decontaminated patients or patients not requiring decontamination should be transported to a medical facility. "Body bags" are not recommended.
Report to the base station and the receiving medical facility the condition of the patient, treatment given, and estimated time of arrival at the medical facility.
If acrolein has been ingested, prepare the ambulance in case the victim vomits toxic material. Have ready several towels and open plastic bags to quickly clean up and isolate vomitus.
Multi-Casualty Triage
Consult with the base station physician or the regional poison control center for advice regarding triage of multiple victims.
Patients who are seriously symptomatic (as in cases of chest tightness or wheezing), patients who have histories or evidence of significant exposure, and all patients who have ingested acrolein should be transported to a medical facility for evaluation. Others may be discharged at the scene after their names, addresses, and telephone numbers are recorded. Those discharged should be advised to seek medical care promptly if symptoms develop (see Patient Information Sheet below).
top
Emergency Department Management
- Hospital personnel in an enclosed area can be secondarily contaminated by direct contact or by off-gassing vapor from soaked skin or clothing. Patients do not pose contamination risks after contaminated clothing is removed and the skin is washed.
- Acrolein is irritating to mucous membranes, skin, eyes, and the respiratory tract. Acute inhalation exposure may lead to respiratory distress and noncardiogenic pulmonary edema.
- There is no antidote for acrolein. Treatment consists of respiratory and cardiovascular support.
Unless previously decontaminated, all patients suspected of contact with acrolein liquid and all victims with skin or eye irritation require decontamination as described below. Because acrolein reacts with the skin, don butyl rubber gloves and an apron before treating patients. Acrolein readily penetrates most rubbers and barrier fabrics or creams, but butyl rubber provides good skin protection. All other patients may be transferred immediately to the Critical Care Area.
Be aware that use of protective equipment by the provider may cause anxiety, particularly in children, resulting in decreased compliance with further management efforts.
Because of their relatively larger surface area:body weight ratio, children are more vulnerable to toxicants that react with the skin. Also emergency room personnel should examine children's mouths because of the frequency of hand-to-mouth activity among children.
ABC Reminders
Evaluate and support airway, breathing, and circulation. In cases of respiratory compromise secure airway and respiration via endotracheal intubation. If not possible, surgically create an airway.
Treat patients who have bronchospasm with an aerosolized bronchodilator such as albuterol. Consider that acrolein inhalation may cause hypertension and tachycardia, in which case the use of bronchodilators that are known cardiac sensitizing agents may pose enhanced risk. Administer corticosteroids as indicated to patients who have persistent wheezing or hypersensitivity pneumonitis.
Consider racemic epinephrine aerosol for children who develop stridor. Dose 0.25-0.75 mL of 2.25% racemic epinephrine solution; repeat every 20 minutes as needed, cautioning for myocardial variability.
Patients who are comatose, hypotensive, or have seizures or ventricular arrhythmias should be treated in the conventional manner.
Basic Decontamination
Patients who are able may assist with their own decontamination. Remove and double-bag contaminated clothing and all personal belongings.
Flush exposed skin and hair with water for 2 to 3 minutes (preferably under a shower), then wash thoroughly with mild soap. Rinse thoroughly with water. Use caution to avoid hypothermia when decontaminating victims, particularly children or the elderly. Use blankets or warmers after decontamination as needed.
Flush exposed eyes with plain tepid water for at least 15 minutes. Remove contact lenses if easily removable without additional trauma to the eye. If pain or injury is evident, continue irrigation while transporting the patient to the Critical Care Area.
In cases of ingestion, do not induce emesis. If the victim is alert, asymptomatic, and has a gag reflex, administer a slurry of activated charcoal at a dose of 1 g/kg (infant, child, and adult dose) if it has not already been administered. A soda can and a straw may be of assistance when offering charcoal to a child.
Victims who are conscious and able to swallow should be given 4 to 8 ounces of milk or water (not to exceed 15 mL/kg in a child) if it has not been given previously (see Critical Care Area below for more information on ingestion exposure).
Critical Care Area
Be certain that appropriate decontamination has been carried out (see Decontamination Area above).
ABC Reminders
Evaluate and support airway, breathing, and circulation as in ABC Reminders above under Decontamination Zone. Establish intravenous access in seriously ill patients if this has not been done previously. Continuously monitor cardiac rhythm. Patients who are comatose, hypotensive, or have seizures or cardiac arrhythmias should be treated in the conventional manner.
Inhalation Exposure
Administer supplemental oxygen by mask to patients who have respiratory symptoms. Treat patients who have bronchospasm with an aerosolized bronchodilator such as albuterol. Consider that acrolein inhalation may cause hypertension and tachycardia, in which case the use of bronchodilators that are known cardiac sensitizing agents may pose enhanced risk. Administer corticosteroids as indicated to patients who have persistent wheezing or hypersensitivity pneumonitis.
Consider racemic epinephrine aerosol for children who develop stridor. Dose 0.25-0.75 mL of 2.25% racemic epinephrine solution; repeat every 20 minutes as needed, cautioning for myocardial variability.
Skin Exposure
If the skin was in contact with liquid acrolein, chemical burns may occur; treat as thermal burns.
Because of their relatively larger surface area:body weight ratio, children are more vulnerable to toxicants affecting the skin.
Eye Exposure
Continue irrigation for at least 15 minutes. Test visual acuity. Examine the eyes for corneal damage and treat appropriately. Immediately consult an ophthalmologist for patients who have corneal injuries.
Ingestion Exposure
Do not induce emesis. If the victim is alert, asymptomatic, and has a gag reflex, administer a slurry of activated charcoal at a dose of 1 g/kg (infant, child, and adult dose) if it has not already been administered. A soda can and a straw may be of assistance when offering charcoal to a child.
Victims who are conscious and able to swallow should be given 4 to 8 ounces of milk or water (not to exceed 15 mL/kg in a child) if it has not been given previously.
Consider endoscopy to evaluate the extent of gastrointestinal-tract injury. Extreme throat swelling may require endotracheal intubation or cricothyrotomy. Gastric lavage is useful in certain circumstances to remove caustic material and prepare for endoscopic examination. Consider gastric lavage with a small nasogastric (NG) tube if: (1) a large dose has been ingested; (2) the patient's condition is evaluated within 30 minutes; (3) the patient has oral lesions or persistent esophageal discomfort; and (4) the lavage can be administered within one hour of ingestion. Care must be taken when placing the gastric tube because blind gastric-tube placement may further injure the chemically damaged esophagus or stomach.
Because children do not ingest large amounts of corrosive materials, and because of the risk of perforation from NG intubation, lavage is discouraged in children unless performed under endoscopic guidance.
Toxic vomitus or gastric washings should be isolated, e.g., by attaching the lavage tube to isolated wall suction or another closed container.
Antidotes and Other Treatments
There is no antidote for acrolein. Treatment is supportive of respiratory and cardiovascular functions.
Laboratory Tests
Routine laboratory studies for all exposed patients include CBC, glucose, and electrolyte determinations. Patients who have respiratory complaints may require pulse oximetry (or ABG measurements), chest radiography, and peak-flow spirometry.
Disposition and Follow-up
Consider hospitalizing patients who have histories of significant inhalation exposure and are symptomatic (e.g., chest tightness or wheezing) or who have ingested acrolein.
Delayed Effects
Pulmonary edema may be delayed for 24 hours after inhalation exposure and respiratory dysfunction may remain for as long as 18 months after exposure.
Patient Release
Patients who remain asymptomatic for 24 hours after exposure may be discharged with instructions to seek medical care promptly if symptoms develop (see the Acrolein--Patient Information Sheet below).
Follow-up
Obtain the name of the patient's primary care physician so that the hospital can send a copy of the emergency department (ED) visit to the patient's doctor.
If significant inhalation or skin contact has occurred, monitor pulmonary function. In rare cases individuals may be permanently sensitized and may need to be removed from future work with acrolein; patients should consult an occupational medicine or pulmonary specialist before returning to work that entails exposure to acrolein.
Patients who have corneal injuries should be reexamined within 24 hours.
Reporting
If a work-related incident has occurred, you may be legally required to file a report; contact your state or local health department.
Other persons may still be at risk in the setting where this incident occurred. If the incident occurred in the workplace, discussing it with company personnel may prevent future incidents. If a public health risk exists, notify your state or local health department or other responsible public agency. When appropriate, inform patients that they may request an evaluation of their workplace from OSHA or NIOSH. See Appendix III for a list of agencies that may be of assistance.

Patient Information Sheet
This handout provides information and follow-up instructions for persons who have been exposed to acrolein.
Print this handout only.
24kWhat is acrolein? Acrolein is a colorless to pale-yellow liquid with a strong, pungent odor. Acrolein is principally used as a biocide to control plants, algae, molluscs, fungi, rodents, and microorganisms. Acrolein has also been used in the manufacture of other chemicals, as a warning agent in gases, as a test gas for gas masks, in military poison gases, in the manufacture of colloidal metals, in leather tanning, and as a fixative in histology.
What immediate health effects can be caused by exposure to acrolein? Low levels of acrolein in the air can irritate the eyes, nose, throat, and lungs and cause cough, chest tightness, and shortness of breath. Higher levels can cause a build-up of fluid in the lungs, which may cause death. If liquid acrolein comes in contact with the skin or eyes, it can cause severe burns. Generally, the more serious the exposure, the more severe the symptoms.
Can acrolein poisoning be treated? There is no antidote for acrolein, but its effects can be treated and most exposed persons get well. Seriously exposed persons may need to be hospitalized.
Are any future health effects likely to occur? Respiratory dysfunction may persist for over a year. In rare cases, after exposure to acrolein, certain persons can be sensitized so that even small exposures to acrolein or other irritants can trigger allergic reaction. Therefore, it is important to tell your doctor that you have been exposed to acrolein. The Department of Health and Human Services has determined that acrolein may possibly be a human carcinogen, based in part on limited evidence of cancer in rats that were exposed to acrolein in the drinking water for a lifetime.
What tests can be done if a person has been exposed to acrolein? Specific tests for the presence of acrolein in blood are not available. If a severe exposure has occurred, respiratory function tests and a chest x-ray may show whether lung damage has occurred. In some cases, lung damage may not be noticed immediately following exposure. Specialized tests exist for reacted hemoglobin in blood and for modified DNA in white blood cells.
I just read through the whole Al Bundy debacle. What I want to know is this - why didn't it occur to anyone to make up a "Peg Bundy" user name to converse with him? I'll admit, it's kind of troll-y but damn it would have been funny!
Folks,
The VG in our e-cigs will not convert to vapor if it does not hit the boiling point which is 290 °C (554°F). That is 10 more than the 280 required to decompose it into acrolein. So the real question that remains to be answered is that how much of that vapor has acrolein in it and how much of it actually does end up getting into our bodies.
P.S: I am new to e-cigs, just tried my first npro, not really happy with it. I'm hoping to get on to something else that will give vapor as much as a real cigarette and was really tending to buy the VG juice once I get my hands on the right device.

Brobby --put your mind at ease and read this report which confirms IMO there is no production of acrolein in our e-cigs---Sun

I pretty much concluded glycerin was safe to use but I do tend to keep an eye on the vapor.
Just to make myself feel a bit better, I went to the link and read. Now, in English, would someone explain how it's concluded that Glycerin doesn't produce acrolein.
