The Evolution of Nicotine in E-Liquids

Must read

Electronic cigarettes were first introduced in the U.S. in 2006. They started as devices that gave people nicotine and have become more complex. People can change them and use them to take different illegal drugs.

The quick growth of electronic cigarettes (e-cigarettes) has changed how people use tobacco and start a big argument about how safe and helpful these devices are. E-cigarettes have liquids with nicotine in them, and these liquids have changed a lot since they first came out. In this blog, we’ll talk about how nicotine in e-cigarettes has changed from when it started to now. We’ll look at the improvements, problems, and what they mean for people using them.

The Early Days: Nicotine and E-Cigarettes

The idea of e-cigarettes goes back to the 1960s, but they started to look like the ones we now use in the mid-2000s. At first, the goal was to make something that people could use instead of smoking to get nicotine, but without the harmful things that come from burning regular tobacco. The liquids used in e-cigarettes, called e-liquids, became the way to give people nicotine.

In the beginning, the e-liquids had a type of nicotine called “freebase nicotine,” which is the kind mostly found in regular cigarettes. This nicotine is more robust and can become vapour at high temperatures. Because of this, e-cigarettes had to be used at higher temperatures, which could sometimes feel harsh on the throat, especially for people new to using them.

The Advent of Nicotine Salts

The desire to replicate the nicotine delivery experience of traditional cigarettes led to the innovation of nicotine salts in e-liquids. Nicotine salts are a modified form of nicotine chemically bound to an organic acid, creating a smoother and less harsh vaping experience. This breakthrough allowed higher concentrations of nicotine to be used in e-liquids without causing excessive irritation, making them particularly appealing to individuals looking to transition from smoking to vaping.

Nicotine salts also offer quicker nicotine absorption, closely resembling the rapid nicotine delivery provided by traditional cigarettes. This property made them famous for smokers seeking a satisfying and familiar experience. Additionally, the reduced vapourization temperature of nicotine salts meant that smaller, more discreet devices could be designed, further contributing to the widespread adoption of e-cigarettes.

About the Right Nicotine Strength

When you start using a vape, one of the first things people will suggest is to pick the right amount of nicotine for you. This is important for a few reasons. The most important one is that it should be strong enough to help you not crave cigarettes anymore. But you don’t want it to be too strong, or it might feel too harsh and make you dizzy.

For those switching from smoking to vaping, opting for a higher nicotine level, around 18mg to 20mg, might be the right choice. However, there’s a challenge with the most common nicotine type found in vape liquids, known as freebase nicotine. As the nicotine strength increases, the sensation in your throat can become more intense, potentially making it uncomfortable. On top of that, freebase nicotine can introduce a peppery flavour that might affect the taste of your chosen best e-liquid flavours.

Lately, something called nic salts has come out. They make it easier and more enjoyable for people to use higher nicotine levels when they vape. Nic salts were first used primarily on small devices called closed pod kits. But now, you can find them in different strengths in small bottles and disposable vapes.

Customisation and Gradual Reduction

With the growth of the vaping industry, a visible trend towards personalisation has developed. Vapers were no longer content with standardised options but instead clamoured for the ability to tailor their vaping experience to their individual preferences and requirements. This marked the genesis of a significant development within the industry – the creation of e-liquids encompassing a spectrum of nicotine concentrations.

This innovative progression catered to various vapers, acknowledging their varying nicotine needs. For those accustomed to heavy smoking, e-liquids with elevated nicotine levels provided a bridge to transition from traditional cigarettes. Concurrently, those seeking to curtail their nicotine reliance found solace in the availability of e-liquids with lower nicotine content or even nicotine-free alternatives. This assortment empowered vapers to take on a nuanced journey towards reducing their nicotine dependency at a pace that resonated with their comfort and preferences.

In response to this burgeoning demand for tailored nicotine intake, numerous e-liquid manufacturers swiftly adapted their offerings to encompass a comprehensive array of nicotine strengths. This proliferation of options mirrored the gradual approach often employed in nicotine replacement therapies, endorsing a measured step-down strategy that facilitated users’ pursuit of diminishing nicotine consumption. By embracing this methodology, individuals were better equipped to align their vaping routine with their aspirations of overcoming smoking habits, fostering a potentially more effective avenue towards smoking cessation.

In essence, the trajectory of the vaping industry was reshaped by the genuine quest for personalisation, wherein the realm of nicotine concentrations and customisation emerged as a pivotal cornerstone. This evolution showcased the industry’s responsiveness to consumer needs and underscored its commitment to supporting healthier lifestyle choices through tailored and adaptable solutions.

Challenges and Regulation

Despite the advancements, the evolution of nicotine in e-liquids has been challenging. The rapid growth of the vaping industry raised concerns about the accessibility and appeal of flavoured e-liquids to younger individuals. In response, regulatory bodies worldwide began implementing restrictions on flavours and marketing practices to mitigate the potential for youth initiation.

Additionally, the health implications of vaping and nicotine consumption remain areas of ongoing research and debate. While e-cigarettes are generally considered less harmful than traditional cigarettes due to the absence of combustion, questions about the long-term effects of inhaling nicotine and other e-liquid components persist.


The journey of nicotine in e-liquids has been marked by innovation, customisation, and the pursuit of harm reduction. From the early days of freebase nicotine to the advent of nicotine salts and customisable nicotine concentrations, the vaping industry has continually evolved to meet the preferences and needs of users. As regulations and research continue to shape the landscape, the future of nicotine in e-liquids will likely be influenced by ongoing efforts to balance harm reduction for smokers and potential risks for non-smokers, particularly the younger generation.
