What do I like look for? Seems like the juul uses my method

Nicotine salts exhibit faster uptake with similar Cmax in humans.

The reason freebase is more effective with a combustion product is because smoke molecules are smaller than vapor molecules, meaning the nicotine has greater exposure due to surface area. Theoretically speaking, if you removed the ammonia from a cigarette and smoked just the nicotine salts your body would receive a higher dosage than an equivalent amount of nicotine salts which were vaporized. It's the method of delivery which makes it more effective, not the type of nicotine. The transition from salts into freebase is merely a preservation method.

I'm not arguing that nicotine salts at the time of vaporization is something that may be worthwhile, depending on what the person wants. Personally speaking, I've tried nic salts and I'm not a fan, but they have their uses.

The issue I have is people who believe that adding benzoic acid to freebase nicotine creates a bottle of nicotine salts. Which simply isn't the way the chemistry works. If you want nicotine salts at the time of inhalation, it's an alright stopgap assuming you adjust the dosage to account for the non-nicotine additives. But if you want some of the additional properties of nicotine salts, such as increased shelf life, adding benzoic acid doesn't help; you end up with a bottle of freebase that has an additive in it.

But the people offering these solutions don't include these disclaimers. It's not "Get a nicotine salt experience with freebase", it's inevitably treated like some sort of alchemical "Turn freebase into nic salts" solution, which is at best a misunderstanding of the science, at worst disingenuous.

I'm not going to go into the process for a couple of reasons.

• It's available for people who want it. Being chemistry, it's just a matter of applying the correct process.
• I do not believe it can be done once the nicotine has been diluted with PG and/or VG. The vast majority(with one possible caveat, see later) of nicotine salt creation is done prior to dilution. Because talking about home use of anything above 100mg/ml is not allowed, I am not willing to risk it.

Now, the caveat to this is that it's possible Juul has decided to essentially take your route with nicotine salts; they create a nicotine/PG/Benzoic Acid solution, which then catalyzes into salts at the point of vaporization. I do not know Juul's operating structure, but if they do not create nicotine in-house it would allow them to get massive amounts of nicotine, of which freebase is the most plentiful, and then convert it into something which, for the purposes of vaping, acts as nicotine salts.

But, once again, it would not have the same properties of nicotine salts before the literal point of vaporization, meaning the shelf-life would be treated as freebase and the mixtures would need to be modified to account for the added benzoic acid.

I'm going to very briefly touch on how a company might broadly handle undiluted nicotine. Mods, if I'm out of line here, please feel free to delete this part.

Being as how they're a large company, though, I'm guessing they could course correct this by either mixing with undiluted nicotine, and treating benzoic acid as an additive to all their recipes, or if they dilute it in house for usage on an assembly line, taking the added benzoic acid into account so their final dilution is still XXXmg/ml. My guess is the latter, because undiluted nicotine is a bitch to handle and accidents would be catastrophic.
