What is a short fill e liquid?
A short fill e liquid usually comes in a 50 ml bottle. These bottles, unlike others, are only filled to about 80 % of what they could be and are often nicotine-free. This is so that users can add their own nicotine to the bottles. Known as nicotine shots, these bottles are sold separately and are made of concentrated nicotine liquid. You can add as you please, most users adding around 10 ml of 18 mg nicotine to every 50 ml short fill bottle before shaking well to allow the two liquids to mix. This varies from person to person, each having their own tastes when it comes to nicotine hits in their vape juice.
Why do people use short fills?
Short fills fulfil a specific need, the juices being used having a wide range of tastes and the possibility for flexible nicotine intake.
With so many ex-smokers coming from differing ranges of addiction, the usual nicotine contents of prefilled vape juices range from 3 mg per 5 ml to 20 mg. The lower the nicotine content, the less ex-smokers used to smoke. With nicotine in prefills consisting of 3 mg, 6 mg, 12 mg, 18 mg and 20 mg, there are bound to be some vapers who have needs falling between these categories. Instead of settling for the prefills, they may want to mix and match to DIY their perfect concentration.
Nicotine-less vape juices
Some people may buy pre-fills due to wanting no nicotine at all in their vape juices. Whilst e cigarettes were originally designed as smoking cessation tools, vape juices have begun to be used by non-smokers who enjoy the taste and sensation alone, disregarding the nicotine. The safest option for these vapers, who may not want to risk addiction, is to go for the nicotine free short fills and use them as is.
TPD laws and short fill liquids
Another reason for the use of short fills is to bypass the Tobacco Products Directive, a set of laws which were laid out last year in the UK. These laws state that you cannot prefill bottles of vape juice with more than 20 mg of nicotine, which may frustrate the vaper who is used to vaping more. These vapers can buy their own nicotine shots and administer as much nicotine as they like to their juices. Take note though, in high concentrations, nicotine can be poisonous.
