E- Liquids – A comprehensive Guidebook

E-Liquid is a fluid which is an essential component of the E-cigarette that fuels it. All electronic cigarettes, irrespective of whether they are using pre-filled cartomizers or a fluid tank system, require e-liquid to produce inhaled vapor.
The main ingredients of E-liquids are Nicotine, flavouring agents and diluents.

  • Nicotine: Most e-liquids contain nicotine, but the level of nicotine varies in different liquids. You can get zero level nicotine e-liquids and different levels of it depending on your preference.
  • Nicotine is the stimulant in e-cigarettes and the substance that is addictive.
  • Flavouring: Since nicotine has no distinct taste, in order to produce taste in your e-liquid flavouring agents need to be added. There is a wide variety of flavours available in e-liquids today; you can name a flavour and you will get it. Few very popular flavours are tobacco, mint and fruit.
  • Diluents: this third ingredient of e-liquid performs three functions. The first function is to dilute the mixture of nicotine and flavours to the exact strength. Next, it adds the part of the solution that produces the vapor which is inhaled and carry the nicotine and flavour mix from e-cigarette to the user and lastly ,it generates the sensation known us ‘throat hit’, when smoke and flavour hits back of the throat.
  • Commonly used diluents to make vapor are:
    • Propylene Glycol (PG): This produces less vapor and more juice. It dilutes the nicotine flavour mixture to the correct thickness and helps to produce the ‘throat hit’.
    • Vegetable Glycerine (VG): vegetable glycerine is thicker and it helps to produce more vapor and adds little sweetness to the mixture.
    • Aqueous Glycerine (AG): As this is very thick, de-ionized water is added to reduce its thickness and this is used when you mix your own e-liquid at home.

E-Liquid Strength: The strength of your e-liquid is the amount of nicotine in a set volume of e-liquid.  Your individual e-liquid strength depends on many factors. There are different opinions on how much strength a daily one pack regular cigarette smoker needs; some say that it is 1.2% nicotine in their e-liquid and many say that they require more. Now e-liquid manufacturers are often referring to the percentage of nicotine in the solution. That is each 1mg/ml of e-liquid contains by volume 0.1% of nicotine, using this notation, an 18mg/ml e-liquid contains 1.8% nicotine.

If a conventional cigarette packet says that it has 1.8 mg of nicotine in the product, it means that each cigarette in the pack has 1.8mg nicotine in it, which makes the total nicotine content of a pack of 20 cigarettes 36 mg. When you consume or ’vape’ e-liquid with 1.8% strength, it means you are inhaling 18 mg of nicotine with each one ml of the e-liquid which makes it equal to the nicotine provided by 10 1.8 mg regular cigarettes.
E-Liquid Quality: No E-liquid will taste exactly like a normal cigarette because of the absence of tobacco in it. You can choose from a wide variety of E-liquids available, varying from natural and organic to nicotine free e-liquids according to your preference. Always remember to keep your e-liquid in a cool and dry place which is not exposed to direct sunlight.
