Ever since Temperature Control came to the market, not a week seems to go by without someone stating that vaping with Nickel wire is dangerous, or at the very least unsafe due to a number of reasons. Every time, the person saying this is often well spoken and seems to be some what knowledgeable on the subject. So lets get into what the dangers are, if any, and what we currently know about Nickel and Ni200 wire.
1 Nickel Leeching
One that pops up semi-regularly is that Nickel apparently gets soft in liquids when hot and thus leeches into the liquid. Scary when you think of vaping Nickel infused juice, which, if possible, could lead to Nickel poisoning, lung cancer, and fibrosis. The problem with this fear is that while it is true, it is not true for how we use Nickel in vaping. Nickel melts at 2,651° F and is a rather stable metal. Which is why we see it used in orthodontics, in jewelry, and so on. You can cause Nickel to soften in liquids and leech into said liquids, but those liquids must be a strong acid, such assulfuric acid, and require the metal to be grinded fine and pulped. Nickel simply is not water soluble, nor is it soluble in PG or VG.Needless to say that our vaping equipment, even 200W devices, are incapable of causing Nickel to leech into our juice, unless you have a strong acid in your tank and in which case, you have far more serious issues to deal with.
2 Nickel Melting
Another fear that pops up occasionally, that also ties back into the fear about Nickel Leeching. Nickel melts at 2,651° F unless a strong acid is used to cause Nickel to melt. Our vaping devices do not reach such high temperatures. In point, Kanthal FeCrAl alloy has a melting point of 2,190°F (1,200 °C). Now, if you make a coil and it has a hot spot, then yes, if you fire your device at high wattage then the hot spot can cause the wire to overheat and snap, but there is no melting occurring. Also, a hot spot is typically found out far before you vape on said coil. In short, there is no need to worry about your Nickel wire melting. Think about it, if coils were melting on us in our devices, we would have figured it out long before Ni200 and Temperature Control hit the market.
3 Nickel Is Too New
This fear deals with how quickly we are moving towards using Ni200 wire and how new this wire is in the vaping community in it’s use. The concern leans heavily towards the argument that since it is new to vaping, coupled with the lack of studies dealing with vaping while using Ni200 coils, then there could be unknown dangers in using it. It is a good point. Whenever you are ingesting or inhaling any substance, it is always smart to understand what the dangers are and what the risks are. No once can say with any certainty that vaping is 100% safe. Everyone who vapes understands this, or at least they should. However, there are countless studies showing that vaping is FAR safer than smoking. Perhaps vaping is not as safe as breathing in unpolluted mountain air for every single breathe you take, but there are studies that show vaping is safer than walking around a city street. Another aspect of this fear is that those who spout it are seemingly unaware that Nichrome wire, which has been used throughout the vaping community until Kanthal overtook it in 2012 due to easier availability and lower price, is 80% Nickel. And Nichrome, being an alloy of Nickel, has a lower melting temperature than Ni200 does.
4 Nickel Allergies
This is one fear that does have a basis in truth. You can find jewelry that states it does not contain Nickel due to roughly 10-20% of the population has some sensitivity to Nickel, causing rashes when held against the skin for too long. While I have heard from many people who have a Nickel allergy state that they have no reactions when using Ni200 or Nichrome wire, there are also those who state that they get a sore throat or an itchy feeling in their throat while vaping and afterwards. If you have a Nickel allergy, I would recommend against using Ni200 coils, as well as Nichrome. If you do not have a Nickel allergy then there are no health concerns that I am aware of that should encourage anyone to stay away from using Ni200 coils for Temperature Control.
5 Vaping With Nickel Causes Carbon Monoxide
Heating Nickel can cause Carbon Monoxide, which is where this fear comes from. But there are some very specific conditions that must be met before Nickel produces Carbon Monoxide which are not capable in our vaping devices. First, the temperature of the Nickel must be near combustible temperatures, meaning over 2,000°F. Our vaping equipment does not reach that high, especially with wicking, juice, and airflow helping to keep the coils cool. Secondly, you must have a fuel-rich, i.e. low oxygen, environment, whereas our devices are oxygen-rich. Even if you were able to your Ni200 coils over 2,000°F then, coupled with the oxygen-rich environment in our tanks and RDA’s, the coils would produce Carbon Dioxide, not Carbon Monoxide. If there was any possibility of Ni200 coils could create Carbon Monoxide, the first person who used them would breathe the vapor in, where it would decompose, giving them a dose of carbon monoxide and depositing some nickel on their lungs. If they survived the first few hours, the nickel causes a form of pneumonia, coughing, breathlessness, extreme fatigue. This lasts for several days, often resulting in cardiovascular or renal failure and death. It is clear that this is not happening to anyone, much less everyone, who vapes using Ni200, or even Nichrome.
What Does All This Mean?
So there you have it. Vaping with Nickel is safe for the way that we use Ni200 wire. Is it 100% safe? I would think not, due to the very nature of vaping. It is safer than smoking, far safer, and it is safer than walking around a busy city street or sitting in traffic while breathing in car exhaust for a few minutes. There are no clear and present dangers while using coils made from Ni200 wire, especially for use with Temperature Control. In short, if you are wanting to use Temperature Control devices, keep using those Ni200 coils and vape on.
And if you have heard of any other theories and/or fears concerning Nickel and why we shouldn’t vape with it, let us know. That was we can research the issue and update this post with any and all relevant information. We are dedicated to keeping vapers aware of the issues that concern them.
