The flavour in the eJuice varies from where it comes from, what components were used to make the liquid, and what flavourings were added. Naturally derived nicotine manufactured from organic plant sources usually taste better and are safer to use than synthetic nicotine. Natural flavourings from flavour concentrates are usually added to the liquid to give its distinctive flavours. These flavours are usually the same flavouring used to flavour food and candy.
What is eJuice made up from and what determines consistency?
eJuice is usually made up of mostly a propylene glycol (PG) or vegetable glycerine (VG) base. Most eJuice are made entirely of propylene glycol but produce less vapour as the (VG) caries the vapour and (PG) the flavour; some are made in a combination of the two depending on the consistency desired. Some people may be allergic to propylene glycol, so a vegetable glycerine base is better suited to their preference. These eJuice bases, flavourings, and sometimes a small amount of distilled alcohol or water are added all contribute to the flavour and throat hit of the eJuice.
Throat hit is the sensation felt in the back of the throat when the vapour is inhaled. In the early days of vaping, people felt vaping an e-cigarette were like inhaling air instead of the smoking sensation they enjoy compared to real cigarettes. Increased throat hit makes using an e-cigarette feel and taste more like real smoking. The liquid base, concentration of nicotine, and voltage of the e-cig affects the liquid’s throat hit.
eJuice is diluted with pure PG or VG to a safe concentration of 12mg – 24mg per millilitre of liquid. A typical full flavoured analogue cigarette contains about 18mg of nicotine. The nicotine concentration desired varies among people, but a normal typical range for most smokers is around 12mg - 18mg. As the concentration of nicotine increases, the throat hit is substantially increased. 0mg eJuice usually feel more like inhaling warm flavoured air, whereas 24mg may be more suitable for experienced or extreme vapours. Every nicotine concentration is unique for each person based on their tolerance level, years they have been smoking, and what type of tobacco they have smoked. Typically, it is recommend that new vapours begin with 6mg - 12mg to determine tolerance for a few weeks, then slowly decrease or increase the strength depending on how they feel. It is recommended that the concentration of the liquid is lowered about 4mg every 3-4 weeks with the goal to ultimately reach 0mg; slowly easing the body off nicotine dependence.
Is eJuice safe to use?
Most of these components in e-liquid are well known and are used in many food products such and household products. Currently only pharmaceutical grade (USP) or food grade PG and VG are safe to use. eJuice contains nicotine and should only be used and handled by adults 18+ or 21+ or older depending on your country's laws. Please be aware that nicotine is a known poison and stimulant. E-liquid should never be handled by anyone under-age and should only be used by people who are smokers and have a tolerance for nicotine. In small concentrations such as 18mg and below, e-liquid is safe to handle. Should any amount get on your skin, wash and clean with soap and water.
