Is Nicotine Salt Safe?
Since the only difference between nicotine salt eliquid and standard eliquid is the inclusion of benzoic acid, nicotine salt is probably no more or less safe than freebase nicotine eliquid. But it is still very safe for people to vape, based on WHO safety instruction: no more than 5mg per kilogram of body weight per day, which would equal about 345 mg for a 150-pound person — probably an impossible amount to vape.
How Do I Use It?
Nicotine salts were created for a specific purpose — a strong nicotine hit from small, portable devices. Pod systems work great for them.
