Preparing your own vape juice requires you to blend the main constituents that form an e-liquid: nicotine, base liquid of VG (Vegetable Glycerin) and PG (propylene Glycol), and flavors. Nevertheless, you do not necessarily require all these components, for example, perhaps you prefer a nicotine-free or unflavored e-liquid implying that the unwanted elements will be eliminated.
Although some people think the preparation method could be difficult, it isn't as complicated as people might think. There is no requirement for an advanced knowledge of chemistry. Anyone capable of making their own cocktail can prepare their own vape juice. Although preparing vape juice is perceived to be simple, sometimes the result ranges from just a liquid you might prefer throwing down the drain to the sweetest e-liquid ever.
Regarding the quantity of vape juice you need to make, you can learn how to prepare it anywhere, but there are key ingredients and equipment required: Vegetable Glycerin (VG), Propylene Glycol (PG), flavour, nicotine (in diluted form), and distilled water (alternatively vodka), though nicotine or vodka are not compulsory elements. PG, VG, and flavouring can be used at a bare minimum preparation process.
