Salts are literally nic salts. They take an acid and mix it with the nic which is a base, and a salt is created. Mixing wise they’re identical. A salt acts just like freebase nic. The only difference is you can vary the throat hit.What's the difference between these? Right now I've been using normal nic based juice.
Absolutely no reason at all.Why would I use the nic salts based juice instead? I'm a higher wattage vapor if that matters
IIRC the way it went last time is you were referring to the JUUL research which only applies to their patented process that no one else can use anyway. afaik JUUL doesn’t sell bottled juice at all. Every salt juice not in a JUUL is by definition therefore using a different acid than what JUUL uses.There is alot more than that to the story. Do some proper research. This site has become very loose on correct information than it was early on.
Ok. I think I may be getting your point.I found this on the net its a good rundown on nicotine salts and is in line with the information hashed out in the above listed thread
"
Nicotine salts are simply when the alkali free base nicotine is combined with an acid to produce an ionic salt. Common acids used are citric, malic, tartaric (all food type additives). Salts are much more stable than the nicotine molecule - so for example nicotine wants to react with oxygen and this will degrade the product, however the salt is not as readily able to react because those bonds are already being used. Using salts may be key to ensuring high quality product for consumers in the future, removing issues around long supply chains and manufacture/warehousing requirements.
The amount of nicotine is not changed in a salt, but the molecular weight of a nicotine salt is higher. For example when nicotine(molecular weight 162) is combined with tartaric acid (molecular weight 150) at that exact ratio, you get a larger salt molecule nicotine tartrate (molecular weight 312). This means that when you create the salt only about half (52%) is the active compound - nicotine.
This means that when you see (for example) “50mg/ml nicotine salts” the nicotine is only 26mg/ml. This might have serious implications in jurisdictions where nicotine content is limited but makes no distinction between freebase and nicotine salts. So, for example we get a situation in the EU under the TPD where such devices can not be sold and they would not be effective anyway - 20mg/ml (TDP limit) of this type of nic salt is really only 10.4mg/ml of nicotine - less than half of what the Juul is supposed to use to be effective.
There’s also a factor in how the body “sees” nicotine salts compared to freebase nicotine. The nicotine alkaloid (freebase) is more readily absorbed in the linings of the mouth, throat and nose. This is one reason why nicotine is not so effective for lung inhalation - I recommend nose exhalation, rather like using a pipe, where it becomes *very* effective ;-)
Salted nicotine is more neutral in pH however, and is more effectively absorbed in the lungs. This may be one reason why the Juul device is recommended as being closer to the smoking experience if someone needs that to effectively switch to vaping. (It’s not the whole story though, as I’ll explain)
This is also what the tobacco companies are doing by treating tobacco with ammonia chemistry by the way - changing the pH of the molecule to make absorption in the lungs much faster. That’s the “dirty trick” that we didn’t really find out about until the late 90’s.
The other thing with nicotine salts is that because it is more pH neutral the experience is less harsh at high concentrations. While it’s not limited to high concentration use it can make the experience at these levels much more pleasant (eg Juul - 50mg/ml nic salts, but 26mg/ml nicotine).
I think the effectiveness of the Juul devices is more to do with the high concentration of active ingredient and the good user experience rather than the method of absorption however. High concentrations of freebase are also very effective, but the experience may be different - vapers tend to freak out if you talk about such high concentrations of nicotine, but accept without question the Juul type concentrations of salts. Juul were smart - they never made a big thing about the nic content in their device, and they only sell ONE concentration - very high on a very low power device.
DIYers have been doing this for some time as well. Adding small amounts of acid (usually citric or malic) can modify a flavour, but it can also make the vape much smoother as some of the nicotine is converted to a salt as well. Presumably if you want nic salt without so much flavour modification you would add the acid to the nicotine solution first and let it react, then add that to your e-liquid.
To answer the last part of your question, all of these technologies have been around for some time (a few years). The main technical developments are in delivery methods rather than in the e-liquid themselves. As I said, the difference between 26mg/ml nicotine and 50mg/ml nicotine salts probably isn’t that much really. There is much more difference between using low power mouth to lung devices and high power direct lung devices.
Probably the key thing for smokers wanting to switch to vaping to understand is that mouth to lung devices are much more similar to the smoking experience (tight draw, less vapour) but need much higher concentrations of nicotine in the liquid to deliver the same amount - beyond the TPD limit for sure. After that, the flavour experience and the “throat hit” become key characteristics in being more like a cigarette, or pipe, or cigar etc.
Once you know all this, you’ll see that the TPD limit of 20mg/ml nicotine doesn’t actually achieve much except reduce the effectiveness of the products most useful to smokers wanting to switch to vaping. To a very large extent the industry has done a similar thing by emphasising the use of high power devices with low concentrations of nicotine. Many brands of liquid are impossible to get at over 6mg/ml of nicotine. Is it any wonder that many smokers find vaping to be ineffective"?

I just searched and found it -- It is an answer on quora by a vaper ... doesn't have any further info or citations.got a link by any chance?
Gah. I should have done that before I replied. Thank youI just searched and found it -- It is an answer on quora by a vaper ... doesn't have any further info or citations.

Ok. Read it. All 5 pages full. There so far as I can find no reference at all to a “Kurt the chemist” in the entire thread. This annoyed me greatly.Ok please excuse my frustration on this topic. This thread contains the info and frustrations lol. Read the whole thread, that is important and pay particular attention to Kurt the chemists quoted posts.
Should I switch to nic salts
There so far as I can find no reference at all to a “Kurt the chemist” in the entire thread.
The best explanation so far of nicotine salts and how they work I've been able to find anywhere--from our resident chemist, Kurt, posted years ago in one of our Juul threads.
"There was another inhalation device proposed by Altria some years ago that used the pyruvate salt of nicotine. Nicotine is a base (amine, to be precise). The form we are used to is the "free-base" form, meaning it is just nicotine. But in plants, since it is a base, it can react with any acids present (including water to a small extent), and turn into the "salt" or "acid" form. The chemistry is not hard, but it does require a knowledge of acids and bases.
Suppose there is citric acid (HCA) present with nicotine (Nic). A small amount of these will react:
Nic + HCA ---> Nic-H+ + CA-
CA- is citrate (conjugate base of citric acid). Nic-H+ is the nicotinium ion, which is just Nic with an H+ attached to the amine N. So the product is nicotinium citrate, also known as the citrate salt of nicotine. It is still nicotine, and if absorbed will behave as nicotine in the brain, but the salt has different absorption properties than the free-base Nic.
Oral absorption (mouth, throat, much of what we get when we vape): Generally slower than lung absorption. Free-base absorbs faster than the salt form. This is why some snus has sodium bicarbonate added, to act as a base and turn naturally occurring nicotine salts in tobacco to the free-base form. The HCO3- ion just pulls the H+ off the nicotinium ion.
Lung absorption: faster than oral in general, but hard to do in vapor form (droplets are generally too big to penetrate the lungs as much as orally). Salt form tends to penetrate deeper into the lungs than freebase wrapped in VG/PG droplets. This is because the salt form tends to be a fine solid. So if you could make the nicotine salt with a safe acid, like citric or pyruvic, and somehow atomize the powdery salt, it should get to the lungs more effectively than the free-base form.
But its not just free-base vs salt form. Gaseous free-base nic will get to the lungs just fine. The problem is that is not what we vape. We inhale relatively large droplets of VG/PG that has nicotine free-base contained in them. Make the droplets smaller, or no droplets at all, just gas-phase, and lung absorption increases. Higher heat and/or lower e-liquid viscosity will help this.
It looks like the idea with the Juul is to include nicotine salts (my guess is primarily pyruvate salt, but this is just a guess), and increase lung absorption. This is the only way to get the rapid spike in serum nicotine to mimic smoking, which is primarily lung absorption of naturally occurring nic salts in cured tobacco. This and a very high nic concentration, which also increases the amount absorbed in the lungs. These in combination should provide lung absorption better than just a 50 mg/mL vape.
As far as I can see, there are no other tobacco alkaloids or psychoactives present, just nicotine and nicotine salts.
If I see them being sold in a convenience store, I will probably try it, just to see. But I have been smoke-free for almost 2 years now, and don't think about smoking anymore. What would be of interest is a study that shows the Juul does better for quitting than even good ecigs.
Hope this clarifies things!"
And this:
"Additionally, I think a similar effect might be possible by simply lowering the pH of an e-liquid with a safe acid. I know Vermont Vapor uses citric acid to adjust the pH of their DIY nicotine base, down to about pH 8, which would be a significant amount of citrate salt form compared to free-base form. I have always found that nic to be particularly satisfying, also tastes really good, but I don't know if this is why. It would depend on how solvated the salt is in VG vapor droplets (they only use VG and water, no PG). I don't know if studies have been done on this. Would be expensive to analyze."
What's the difference between these? Right now I've been using normal nic based juice.
Why would I use the nic salts based juice instead? I'm a higher wattage vapor if that matters
Look the chemistry is clear but the rate of absorption will be different due to various salts and human factors.
And the amount of vapor generated by your device. Here's a nice tidbit about Juul, possibly, going for more vapor and less nic.
