eLiquid Juice Safety
Disclaimer: As per FDA regulations a e-Cigarette retailer engaged in the sale of vapor product can not make any health claims regarding electronic cigarette devices. The information found below is not a health claim on behalf of Zee Cigs Vapor and should not be viewed as such. These are quotes from recent news articles and should not be viewed as health claims made by Zee Cigs.
Welcome to ZeeCigs Vapor eLiquid / eJuice Safety and Information Section.
Of the many articles posted on this website this particular subject is vital to e-Cigarette safety and your health when using eCigs, in this article we will go over as much as we can including, eLiquid ingredients, proper storage of your refill eLiquid and eLiquid expiration dates. We feel even avid e-Cigarette vaporer’s might find some golden nuggets hidden through this article as we touch on every point regarding eLiquid / eJuice.
In 2009 we presented the best eLiquid information available at the time and any possible harmful ingredients, however with time and more public exposure to eCigs we found welcomed advice and in many cases expert opinions publishing articles supported with scientific facts, in many cases these opinions resulted in needed changes and welcomed transparency throughout the vapor industry.
This allowed for responsible vapor retailers to make needed changes and updates as new safety information became available. From eLiquid manufacturers to eLiquid flavoring suppliers we have seen some great changes allowing for responsible retailers to offer the best vapor e-Cigarette product available. Below is some of the most up to date information regarding eLiquid safety and in-depth information.
What is eLiquid / eJuice?
If you are brand new to vapor e-Cigarettes you might be wondering what is eLiquid, by the way eLiquid is also called eJuice, Smoke Juice, Nicotine Liquid, Nicotine Juice, Refill Oil and Vape Juice. Whatever you might call eLiquid it’s without a doubt the lifeblood of your vapor e-Cigarette. Both your vapor e-Cigarette and your refill eLiquid are equally as important as one will not work without the other.
However, understanding eLiquid quality and eLiquid ingredients is very important. eLiquid can come in hundreds of flavors with a wide range of quality, several base liquid formulations and dozens of nicotine levels. eLiquid is converted into vapor by your e-Cigarette’s heating element which is commonly called a coil head, this conversion mimics the feel of smoking a traditional tobacco cigarettes. When it comes to eLiquid you certainly get what you pay for so be careful when purchasing cheap vape juice.
What You Need to Know About eLiquid Flavoring and Ingredients.
There are several principal eLiquid ingredients found in a mainstream vapor electronic cigarettes. In this section we will review the base formulas, which are Propylene Glycol and Vegetable Glycerin. From there we will drill down other eLiquid ingredients including known harmful ingredients.
With eLiquid flavoring we will focus on any known harmful ingredients that can be found in your vapor e-Cigarette refill juice. That’s right, we did say harmful ingredients as the FDA regulation failed horribly in addressing this important matter of public safety allowing for USA made eLiquid to contain known harmful ingredients.
Propylene Glycol (PG) in eLiquid
Propylene Glycol or PG as it's referred to in the vaping industry is not only found in e-liquid but thousands of consumer products including food grade products as it’s a known as a non-toxic additive and has been around for a very long time, yes, you can even find Propylene Glycol in some known medications.
The FDA has categorized propylene glycol as "Generally Recognized as Safe." Even with prolonged direct exposure, there is little to no skin irritation or sensitization. Unlike its dangerous and frequently lethal cousin, ethylene glycol. PG is easily metabolized by the liver and approximately 45 percent of any ingested PG is excreted directly from the body and never even comes into contact with the liver. The elimination half-life for Propylene Glycol is approximately four hours.
Why is Propylene Glycol used in vapor e-cigarettes? PG does a great job at retaining food flavoring profiles in eLiquid over time and PG produces what is known as a “throat hit” sensation similar to what traditional tobacco cigarettes offer, however PG fails to produce adequate vapor which is why Vegetable Glycerin is commonly used as VG is great at producing vapor.
VG is known to restrict flavoring and lacks that “throat hit” sensation which is why both PG and VG is used in eLiquid. Propylene Glycol has been extensively studied for nearly half a century with the first extensive study taking place in the 1940’s over a seven year time period. More recent studies have also been conducted including human consumption by inhalation.
To date, PG firmly remains a non-toxic additive but a vapor user should note that PG is offered at different purity levels so keep an eye out for USP grade in the ingredient list, if the PG is not listed as USP grade then it can be a lower industrial grade which we do not recommend vaping. USP Grade means that a product meets all of the requirements as contained in the USP monograph for that the product is manufactured in a cGMP compliant facility. If there is no USP monograph, a material cannot be labeled as USP Grade.
Vegetable Glycerin (VG) in eLiquid
Vegetable Glycerin is produced from plant oil extracts, which includes palm oil, coconut oil and even soy oil. Vapor consumer will commonly assume that Vegetable Glycerin is healthy as the word vegetable is associated with health, however there has been no long term studies on the use of glycerin in vapor inhalants.
VG can be produced at different purity levels. It is highly recommended to seek out USP grade Vegetable Glycerin, if the VG is not listed as USP grade then it can be a lower industrial grade and can contain impurities which is not recommend to vape. USP Grade means that a product meets all of the requirements as contained in the USP monograph for that the product is manufactured in a cGMP compliant facility. If there is no USP monograph, a material cannot be labeled as USP Grade.
100% Pure Vegetable Glycerin eLiquid (VG)
There are very few eLiquid formulas made purely with Glycerin. It is known that VG fails to suspend flavoring properly. For this reason almost all food flavoring is suspended in Propylene Glycol as PG is a great carrier agent allowing for flavoring to properly distribute when eLiquid is mixed.
Vegetable Glycerin can cause the flavor profile to change over time and given enough time, VG will cause changes to the flavor profile, alternatively Propylene Glycol will provide a more stable flavor profile over time. Vegetable Glycerin eLiquids with a very high amount of VG will usually feature the name MAX VG as with MAX VG formulas the flavoring added will be suspended in Propylene Glycol.
Flavoring will account for approximately 10% to 20% of the eLiquids total volume with the rest being VG. One final point to make regarding Vegetable Glycerin is the amount of sweetness detected by vapor consumers. High amounts of Glycerin will result in a much sweeter eLiquid profile.
PG and VG Ratios
While researching different eLiquid brands you may come across PG to VG ratios (not every brand list’s the ratio) and they will look like this, 50PG/50VG, so in this example 50% of the eLiquid is Propylene Glycol and 50% of the eLiquid is Vegetable Glycerin. 50PG/50VG is a common formulation as it balances the flavor and vapor.
Ethyl Alcohol in eLiquid
Not much attention is given to ethyl alcohol but it is found in certain flavors in trace amounts as it is a common ingredient in food flavoring. Ethyl alcohol is not found in every flavor but some eLiquids do have trace amounts of ethyl alcohol. Ethanol and ethyl alcohol, aka grain alcohol or PGA as it's often referred to is all the same stuff. Before you go running to the hills or thinking an eLiquid is the same as NASCAR race fuel you should read on my friend.
Race car fuel is denatured and includes additives which in many cases are poisonous. The main reason for the additives is due to the federal taxation of alcohol, hello ATF agency (United States), without these additives race car fuel is the same thing as grain alcohol such as the popular brand EverClear. With these additional additives it now changes to a formulation not fit for human consumption and is not taxed.
So is ethyl alcohol safe to vape? Ethyl alcohol is the good stuff and it gets confused for methyl alcohol, which is the bad stuff, yup, just adding the “M” changes everything. If you pay attention, many organic food products use organic ethyl alcohol, which you can find in a product's ingredient list.
In many cases it is listed as alcohol with ethyl being omitted from the description, here at Zee Cigs Vapor we do list if an eLiquid has Alcohol in the Technical Specs Section of each eLiquid allowing for the consumer to decide freely.
Of course isopropyl alcohol is poisonous (rubbing alcohol) and you would not want to vape it, you should never use rubbing alcohol to clean your e-Cigarette parts. The issue here is many eCigarette users will scan a eCig forum and see allot of people mention the use of alcohol for cleaning, however they are speaking about ethyl alcohol, aka Everclear, aka cheap vodka.
I hope this section is helpful as almost no mention is ever given on this subject in the vapor world and we can see why as the word “ethyl alcohol” can seem scary without full disclosure. A recent news report by a popular news outlet used “ethyl alcohol” as a scare tactic to further the misinformation regarding eCigarette vaping.
In terms of eLiquid we are speaking of small amounts of ethyl alcohol with some flavors only having a trace amount. If you want to get really technical both Propylene Glycol and Vegetable Glycerin contain small amounts of alcohol.
Diethylene Glycol (DEG), Something You Do Not Want to Vape.
Another common Propylene Glycol misconception that has appeared over the years is the fact that first time eCig users will unknowingly buy a low quality eCigarette containing cheap eLiquid (commonly produced in china ). The most common complaint with these vapor liquids is throat irritation and sinus issues. This is usually due to low quality ingredients and in many cases a lesser known and much more inexpensive base liquid called Diethylene Glycol (DEG) which is known to be harmful.
Reputable eLiquid brands would not even consider using Diethylene Glycol (DEG) as it's harmful to humans. So if you're using a foreign brand eLiquid from china or elsewhere you have been warned, as almost all of these products do not have ingredients listed on the product.
Since we are on the subject of cheap eLiquids now would be a good time to mention that these cheap eLiquids can have other ingredients that can either be harmful or unwanted. In the case of ethyl alcohol we mentioned that small amounts of ethyl alcohol could be found in the flavoring.
Some foreign eLiquid brands may contain very high amounts of ethyl alcohol, in this case the question might not be harm as much as ingestion of unwanted levels of alcohol. A recent Yale University study on e-cigarettes mentions ethyl alcohol and the only conclusion we can make is that the ecigarette cartridges that were tested were a foreign brand as eLiquid is sold by bottle and not within a cartridge with consideration to mainstream vape retailers.
The exception to cartridge type e-Cigarettes here in the USA is found in big box retailers which are almost all made by big tobacco companies such as BluCigs made by Lorillard, Vuse made by RJ Reynolds and MarkTen made by Philip Morris USA.
Antifreeze in Your eCigarette.
Ah, one of the first big misinformation campaigns about e-cigarettes, funny enough it does keep popping up so let's take a moment and speak on this matter, as you do not want to vape antifreeze. Many of the ingredients found in vapor eLiquid are found in thousands of other products.
Vapor eLiquid is not made of antifreeze meant for your car's radiator. So in this instance you could say that “Snow Cones” contain antifreeze as many snow cones contain Propylene Glycol. This information simply is not true and these statements are nothing more than misinformation or worse, lack of proper knowledge.
Nicotine Purity Levels in Vapor Products
In 2009 the FDA banned the importation of electronic cigarettes after performing a study on several electronic cigarette refill cartridges and finding Diethylene Glycol (DEG), which is known to be harmful to humans. Tobacco manufacturers will commonly use Diethylene Glycol (DEG) as a humectant. During this time period nearly all of the nicotine used for making eLiquid was extracted from commercial grade tobacco leaves, which had been exposed to Diethylene Glycol (DEG).
This resulted in the FDA study finding trace amounts of Diethylene Glycol (DEG) enacting a nationwide ban on electronic cigarettes. A couple of years later a federal judge ruled that the FDA’s current evidence was not sufficient and Judge Leon reversed the ban. The FDA has now released eCigarette regulations, however nothing is mentioned in the FDA regulation with regards to possible toxins such as Diethylene Glycol (DEG).
Responsible manufacturers of nicotine liquid (eLiquid) opted to use 99.9% pure pharmaceutical grade nicotine as none of these possible trace toxins would be present compared to the process of extracting nicotine from commercial grade tobacco leaves which can have trace toxins. When purchasing eLiquid / eJuice make sure to check that the eLiquid contains 99.9% pure pharmaceutical grade nicotine as you will avoid the possibility of any possible toxins contained in the nicotine.
Diethylene glycol (DEG) is a poison that kills by damaging the liver and kidneys among other effects. It is very similar to PG in appearance, taste and characteristics,
What You Should Know About Diketones if You Vape
Before we dive into this important section regarding Diketones we want to make it perfectly clear that you have a choice in choosing e-Liquids that contain Diketones as Diketone-free e-Liquids are available, the choice is up to you as reputable brands of e-Liquids (vape juice) will state in writing if any Diketones exist in their flavor profiles (This information is listed in the “Technical Specs” section regarding vape eLiquids offered on this website).
If you’ve been vaping for awhile and you have been around the block in the eCig forums and eCig blogs you may have heard of diketones. Diketones are a recent concern for users of vapor products and we will go in-depth on this subject, as you should be aware of these chemicals.
Diketones are found in food flavoring with pretty much anything that has a buttery or creamy flavor. Within the food industry diketones are required to be tested so that the levels are safe for human consumption, however it is not required by U.S. law to be tested in inhalation products such as vapor eCigarette products since the FDA has not mentioned this in the recent e-cigarette regulation.
Diketones is not one chemical but a group of three chemicals, the chemicals are as follows, Diacetyl, Acetyl Propionyl and Acetoin. Diacetyl is without a doubt the most questionable out of the three and for good reason.
Diacetyl and Vapor Health Risks.
In the 90’s, employees at a factory producing microwave popcorn contracted bronchiolitis, which is a serious health condition. The employees had been inhaling Diacetyl at high levels for years, enough to cause bronchiolitis (aka Popcorn Lung) as the butter flavoring contained Diacetyl. Although the level of Diacetyl that was found in vapor liquid was relatively low compared to traditional tobacco cigarettes, most of the vapor industry decided to ditch the Diacetyl.
We do say “most” as some brands continue to use flavoring that is known to contain Diacetyl and we can think of at least one major e-Liquid (eJuice) USA brand that contains Diacetyl in their e-liquid, however they still have not disclosed any information regarding diacetyl to their consumers.
If you vaped a buttery or creamy flavor eLiquid (juice) in the past you may be concerned that you were exposed to Diacetyl, however we would like to point out that we are speaking of trace amounts that were found in e-Liquid. If you previously smoked traditional tobacco cigarettes then you were exposed to Diacetyl at much higher levels, how high?
A recent study from Dr. Farsalinos' showcased the exposure levels comparing tobacco cigarettes to vapor e-Cigarettes. The study showed a tobacco cigarette contained 6718 micrograms compared to a buttery or creamy flavored eLiquid that contained 9 micrograms of Diacetyl, a newer study was conducted by the Harvard T.H. Chan School of Public Health.
This study resulted in data that smoking a traditional tobacco cigarette resulted in inhaling 750 times more Diacetyl than an eLiquid (vaping e-juice) that contained Diacetyl (butter and cream flavoring). Here are a few of the popular e-Liquid flavors to focus on with regards to Diacetyl, banana nut bread, creamy banana flavors, strawberry and cream, flavors with milk and yogurt flavors, there are many more but hopefully this will give you a better idea into the flavors that might contain Diacetyl.
Acetyl Propionyl and Acetoin in Certain eLiquid (juice) Flavors.
Responsible vaping eJuice Brands and retailers wanted Diacetyl out of their eLiquid formulations as it’s a known health risk to the vaping public, this did become possible after the flavoring manufacturers changed the formula of these specific flavors and offered it in a Diacetyl-free version.
A quick fact regarding Zee Cigs, our Cloudchasor and ÜbberBliss (UbberBliss) premium eLiquid Brands never contained Diacetyl as we were aware of Diacetyl and decided not to offer these flavors until an alternative was available.
Diacetyl was removed by many of the flavoring manufacturers however Acetyl Propionyl and Acetoin were used in place of Diacetyl. These two Diketones are considered to be safe for inhalation, however it is important to note that there is no scientific evidence as to whether acetyl propionyl and acetoin are harmful or not in the form of vapor.
Many vapers avoid these ingredients when purchasing e-liquids since it’s easy to avoid. Simply avoid all e-Liquid flavors that contain buttery or creamy notes. Recent reports have confirmed that Acetyl Propionyl and Acetoin can ‘catalyze’ into small traces of Diacetyl either during the manufacturing process or when the eLiquid is converted from a liquid form into vapor.
Diacetyl Versus Acetyl Propionyl and Acetoin
Diacetyl is known to cause lung conditions when inhaled, currently there is no evidence to show that Acetyl Propionyl and Acetoin will cause similar health risks. Additional research is being performed on eLiquid (e-juice) by professional eLiquid brands and universities across the globe and we will update this article if any new information develops. We recommend that you do not use e-Liquid (e-Juice) that contains Diacetyl as it’s known to pose a risk to your health.
But What About Microwave Popcorn?
Don’t fret, microwave popcorn with butter flavoring (which contains Diacetyl) is just fine for human consumption. Diacetyl becomes harmful when inhaling large doses for a long period of time. Even the heaviest vapor users won’t inhale anywhere near the levels of Diacetyl that the popcorn factory workers previously did, it is still important to note that Diacetyl is a harmful substance that is going straight into your lungs.
Ah, the new kid on the block! Before we dive into Butyric Acid we want to make it perfectly clear that you have a choice in choosing a vape e-Liquid that contains Butyric Acid as these are the buttery and creamy eLiquid flavors used for vaping. We previously spoke about responsible vaping eJuice brands and retailers staying far away from Diacetyl with many sticking with flavors that have Diketones but with the absence of Diacetyl.
Butyric Acid is an alternative to Diketones and many eLiquid brands have decided to use Butyric Acid in place of Diketones. Butyric acid in e-Liquids is viewed as safe based upon current scientific literature, however, to date no studies exist proving that Butyric Acid is safe or harmful by inhalation.
So what is Butyric Acid? Butyric Acid is found in dairy products such as milk, butter, Parmesan Cheese, and is a product of anaerobic fermentation, Goat, Sheep and Buffalo milk have higher amounts of Butyric Acid.
Humans do indeed host Butyric Acid, if you ever found yourself with the flu or had a bit too much to drink you’ve probably paid oral homage to the porcelain king. Afterwards you may have noted a sour smell in the bathroom, which of course is Butyric Acid.
It is a known fact that inhalation of butyric acid can result in throat soreness, burning sensations, difficulty breathing, and coughing. Butyric Acid levels in eLiquid flavoring is very low decreasing the potential of a bad odor or taste.
While there is a downside in terms of potential odor and taste with larger amounts, there's actually an upside to the use of the chemical in general. Butyric Acid inhibits the absorption of Diacetyl if it’s present, if flavoring has both Butyric Acid and Diacetyl then in theory the Butyric Acid will prevent the Diacetyl from being absorbed during inhalation. That doesn't mean that it makes it any safer in terms of inhalation as Butyric Acid has not been thoroughly studied in vapor form.
Storing your eLiquid / eJuice and Expiration Dates
eLiquid is sensitive to both hot and cold temperatures and proper handling and storage should be taken for optimal freshness. First, let's discuss flavoring at the molecular level, flavor molecules are dispersed throughout the eLiquid / eJuice and if properly cared for these flavor molecules will remain relatively intact for a minimum of two years with minimal change to the eLiquid / eJuice flavor profile.
Exposing eLiquid / eJuice to hot or cold temperatures can cause the flavor molecules to crystallize which would result in a loss of flavoring, the more flavor crystallization the more plain or bland the eLiquid / eJuice will taste when vaping. Flavor molecules can be different in size and weight and will act differently when exposed to hot or cold temperatures.
Hot temperatures and UV light causes the biggest changes as flavors with lighter molecules can change into a gas form and escape when the bottle is opened. eLiquid / eJuice flavors with light molecule’s are fruity, light tobacco and sweet flavoring. Heavier flavors such as caramel will commonly crystallize which will also change the flavor profile resulting in a plain or what can appear as a flavorless e-Liquid.
Exposure to UV light will excite flavor molecules, making them significantly more volatile (movers and shakers J). Think of heat and UV light like a form of cooking, as you simmer a soup on a stove the liquid will dissipate over time as you simmer the soup. This process is also true for eLiquid / eJuice. The longer the liquid is exposed to heat or UV light the more flavor molecules will escape resulting in a plain tasting or flavorless eLiquid.
Long Term Storage of eLiquid / eJuice
For long-term storage of your eLiquid / eJuice it is recommended to keep the e-Liquid in a cool dark place within your home with a low level of humidity. You might think that your refrigerator would be the perfect place but the refrigerators colder temperature and humidity is not optimal for storage and can cause the eLiquid / eJuice flavor molecules to crystallize. Short-term refrigeration of eLiquid / eJuice is acceptable but long-term storage is not recommended.
Nicotine, Heat and UV Light Can Cause eLiquid / eJuice to Change Color
Normal temperature changes, body heat (keeping eLiquid in your pocket) and exposure to UV light (sunlight) will change the coloring of eLiquid / eJuice and this is normal. eLiquid / eJuice with nicotine can speed up this process and the more nicotine contained in the e-Liquid the greater the chances of the e-Liquid darkening in color, this too is normal.
Short Term Storage of eLiquid / eJuice
Normal shifts in temperature will not change the flavor profile of your eLiquid / eJuice but freezing temperatures or very hot temperatures will result in flavor crystallization and flavor molecules to escape in a gas form depending on the flavoring. These changes will result in a major change in the flavor profile so make sure not to leave your eLiquid / eJuice exposed to these extremes such as in a car on a hot summer day or a cold winter day.
Steeping your eLiquid / eJuice
You may have considered steeping hot tea but steeping your e-Liquid? Well many consumers of eLiquid swear by it so we will take a moment to explain this process. If you have a brand new bottle of eLiquid / eJuice it may have been manufactured just a day or so before you received it. In this case steeping the eLiquid is recommend as it gives the flavor molecules time to bind within the eLiquid.
How would you know when your eLiquid was made? Respected eLiquid manufacturers should list a expiration date (this is also a sign of a reputable eJuice manufacturer) which can be helpful as most e-Liquid manufacturers use the industry standard of two years from the date of expiration so this would give you a clue to when the e-Liquid was made.
Regarding Zee Cigs, our Cloudchasor and ÜbberBliss (UbberBliss) premium eJuice Brands all have a batch code. The batch code will be a series of numbers, for example 06062017A, in this case the eLiquid was manufactured on 06-06-2017, the A stands for the first batch of that day.
Steeping is a matter of personal preference, some consumers will let e-Liquid steep for up to two weeks if not more, if you are interested in steeping then you may want to start with steeping for a week (make sure to keep the eLiquid in a cool and dark place) from there you can shorten or prolong the steeping process based on your personal habit. Does steeping work? Some swear by it and other discount it as vaping mythology.
eLiquid / eJuice Expiration Dates
Throughout the information listed above we mentioned expirations and shelf life. If you have decided to jump to this section you might want to do yourself a favor and read this entire article to get a better understanding of what affects your eLiquid and how to preserve it’s freshness as consumer error can result in reducing quality and freshness anywhere from a few months, a week or even a few days from purchase.
An expiration date is only an estimation of the date that the product is guaranteed to be the same quality as when it was purchased. With e-Liquid this timeframe is anywhere from one to two years depending on the manufacturer's decision as both Vegetable Glycerin and Propylene Glycol have a established shelf life of two years.
It is accepted in the vapor industry that Nicotine (if properly stored) also has a shelf life of two years. The true wild card is flavoring as different flavors can outlast that two-year mark with some flavors lasting up to five years. Of course this is tied to proper storage, which we previously mentioned.
How Do I Know If My Vape Juice Has Gone Bad?
The first thing to check for is flavor separation. If the bottom portion of e-Liquid seems darker than the top portion than the flavoring has either separated or crystallized. Give the bottle a good shaking for about a minute or so, if the e-Liquid returns to a consistent color then you’re in luck. There is no guarantee as the flavor profile of the lighter flavors may have already dissipated.
If after a minute of shaking the eLiquid has not balanced out in consistency then the flavors have crystallized and no amount of shaking will fix this issue as this process takes place on a molecular level. We would recommend you dispose of the liquid (always safeguard eLiquid from children, unknowing adults and your valued pets).
If your e-Liquid appears fine in coloring you can still do a quick sniff test as you can note abnormalities just by smell, If the eLiquid appears fine but upon vaping the flavoring seems lacking then the flavoring has either dissipated or crystallized. We would recommend you dispose of the liquid (always safeguard eLiquid from children, unknowing adults and your valued pets).
“Vapers Tongue” or as it's also called “Vapor Tongue” is a known situation where you can no longer properly detect or taste a particular e-Liquid flavor. Ironically this has nothing to do with your tongue or taste buds. Your nose detects the majority of flavors and some consumers are more sensitive than others at detecting flavors as over time your senses can fail to detect the flavoring.
The fix in this case is an easy one, just switch your flavor, switching flavors kick-starts your senses, in this case having multiple flavors is a good thing. Of course you can always return to the original flavor as your senses will pick up the flavors that previously were absent.
If you are new to e-Cigarettes you should not confuse “Vape Tongue” with tar build up as vape consumers who are new to vaping commonly use tobacco cigarettes or recently used tobacco cigarettes. In this case tar from smoking has coated your mouth and tongue, which reduces flavor detection. A smoker's taste buds can detect sweet and salty flavors fairly well but a whole spectrum of flavors are missed due to the tar build up, fortunately the tar will dissipate over a week or so.
Cold, Flu and Seasonal Allergies Affects Vaping
Similar to “Vapor Tongue” your senses of detecting flavors can be severely hindered due to a sinus infection, cold, flu or seasonal allergies. Detecting your e-Liquid flavoring will be the first to go well before your detection of flavors in food as your taste buds pick up most flavoring in food. Since the majority of e-Liquid flavor detection is done by your nose these medical conditions will affect the flavor or lack of.
It is common that little or no flavor is detected when vaping, during these conditions lighter flavors are affected the most. When suffering from these medical conditions it is recommended to seek more powerful flavors that contain cinnamon, mint or menthol as you have a better chance at detecting these e-Liquid flavors. You can even mix one of these flavors with your normal “go to” vape flavors, grab a bottle of spearmint and when one of these conditions arises just add some spearmint which increases the flavor profile.
Is it True That Formaldehyde is in Vapor eLiquid
Have you come across “e-Cigarettes Contain Formaldehyde” statements, if not, sooner or later some know-it-all or media educated person might try and scare the pants (or dress) of you with this statement as we all know formaldehyde is harmful and is so toxic that enough of it can result in death.
So here is the real story, there is indeed an electronic cigarettes study that was featured by almost every major news outlet in the USA (aka junk media, oh, Walter Cronkite how we miss you and your generation of reporting). It featured this headline “electronic cigarettes contain formaldehyde”. The real question on this topic is, truth or lie? With every lie there is often a truth or in this case a half-truth. A study was performed on electronic cigarettes and during the study electronic cigarettes passed every health and safety protocol.
At the end of the e-Cigarette study a very powerful vape model was used in testing, during this test the unit was set to maximum power and was fired non-stop with minimal eLiquid /eJuice (We suspect it was a 200 watt unit). During this time formaldehyde, heavy metals and all kinds of toxins were recorded. This is to be expected as the top end of the unit was extremely hot. At these levels no sane person would hold a unit in this condition let alone inhale, I doubt you could inhale, as your mouth would be burnt.
Just like a house fire, when materials burn it creates toxins because it's ON FIRE! Yet again we are presented with sound bites and headlines to shock us. The media reporting this story was legally justified as they also published a link to the full study, the problem is many viewers did not read the entire study which was hidden in a link at the end of the report.
This same study has also produced several articles featuring “Vapor cigarettes contain harmful heavy metals that could be inhaled”. This misinformation all stems from the same study that featured Formaldehyde, and finally, to answer the question “Is it true that Formaldehyde is in Vapor eLiquid”, we can positively say no, the case in point was in regards to a e-Cigarette model that was running with no eLiquid at all at very high temperatures.
