My experimentation w Nic salts. Since I reside in Canada, I cannot buy Nic in salt formulation from U.S. suppliers so I decided to DIY Nic salts. This was my second try, it worked: This was my first try which sucked: The successful, version with a 10% benzoic acid solution has space for about 20% flavoring. This ejuice formulation should only be used with low powered Juul, MyJet type devices. The 100 mg/ml Nic solution used here is a regular NicSelect freebase solution. At first without doing any research, I though that heat was needed to create the salts, it turns out that the reaction is instantaneous. Heat does help to dissolve solids though. Sourced the Benzoic acid on Amazon.com: Benzoic Acid, Guaranteed Reagent. ACS Grade. (500 g) Ships from and sold by Medix Corp.. P.S. I am not affiliated with Medix Corps in any way.
