A peek at the future of vaping technologies
By Stefanie Rossel
As sales of combustible cigarettes continue their downward spiral, reduced-risk products (RRPs) keep gaining ground. Euromonitor International estimated the retail value of the worldwide RRP market at $19.34 billion in 2023 and expects further growth.
Plxsur, the world’s largest group of independent vaping companies, reckons that the 12 markets it operates in are together worth $20.8 billion and will grow to $59 billion by 2033. The company expects RRPs to overtake cigarettes over the next 10 years. “Looking at the U.K. alone, the number of cigarette users is currently at parity with RRP users at around 12 percent of the population, with the latter expected to become the dominant format this year,” says Plxsur’s chairperson and co-founder, David Newns.
In terms of technology trends, a decade is a long time. In the past 10 years, vapers have moved from “cigalikes” to pods then to disposables and now back to reusables again. However, many current vape products still have shortcomings, particularly in areas such as user-friendliness, nicotine delivery and sustainability. Going forward, Newns sees two main considerations driving people to RRPs. “The first is cost-effectiveness, with reusables more cost effective than disposable vapes and certain cigarettes,” he says. “The second is user experience. Technology is constantly evolving, and the category continues to advance RRPs to replicate the delivery of nicotine in a cigarette in terms of speed of delivery and satisfaction.”
Innovation in the category, Newns points out, will depend on two key factors: the delivery of nicotine in a reduced-risk format that satisfies users to a point that they don’t feel compelled to return to cigarettes and the behavioral aspect of smoking. “In order to ensure RRPs are attractive to smokers, the behavioral patterns must not differ dramatically,” observes Newns. This, he says, explains why nicotine patches or gum alone often aren’t successful in helping smokers quit. “Smokers are most successful at quitting when using vapes, either on their own or in combination with other products,” says Newns. “Given the ritualistic elements that vapes provide, which [are] similar to smoking, they are often seen as a natural next step for those looking to quit.”
According to Newns, devices will likely also feature more connectivity functionality in the future.
Enhancing Nicotine Delivery
Optimizing nicotine delivery has been front and center in recent innovations. The German startup Splash, for example, has developed a product that generates a foam instead of vapor (see “Bubbles of Bliss,” Tobacco Reporter, December 2023) while U.K.-based Qnovia has designed an inhaler that works without heating (see “High Tech Quitting,” Tobacco Reporter, March 2023).
Ispire Technology Co-CEO Michael Wang expects constant introductions of novel and unique entries into the nicotine-delivery space going forward. “However, the key factor to consider is efficacy—the actual effectiveness of nicotine delivery, its impact on the body and its absorbency,” he says. “Methods like Splash, which deliver nicotine through a foam in the mouth, or pouches like Zyn result in a different neurological uptake of nicotine. These methods take longer to be absorbed into the bloodstream, delaying the time it takes to reach peak effect. Research supports [the idea] that aerosolization is the most efficient and optimized way to deliver nicotine into the bloodstream for immediate absorption. This efficiency is largely due to particle size and how it is distributed in the body. Aerosolized nicotine, delivered to the lungs, ensures rapid absorption and immediate effect, unlike oral or sublingual methods, which take longer to act.”
Both Wang and Newns anticipate the development of better heating systems that eliminate the metal emissions associated with nichrome wire-based heating systems. “The performance and safety of the core vaporizer technology are critical concerns,” says Wang. “Many devices rely on ceramic heating elements, which, while cost-effective and easy to manufacture, present risks. If the manufacturers do not hold themselves to the highest standard in their manufacturing process, then over time and with repeated heating cycles, ceramics can become brittle and potentially release harmful particles into the vapor. This underscores the need for the industry to move away from ceramics and adopt safer alternatives.”
Wang views the introduction of heating chip technology, as recently launched by Greentank (see “Heated Breakthrough,” Tobacco Reporter, June 2024), as a significant step forward as it performs better on key safety metrics, including the reduction of harmful and potentially harmful constituents. “By using biocompatible materials and moving away from ceramics and heavy metal-producing heating elements, we can improve the safety and performance of vape devices. These innovations aim to minimize health risks and enhance user experience by providing cleaner and more efficient vaporization.”
Precision dosing and dosing control, Wang stresses, are essential yet often inadequately addressed aspects of vaping technology. “Accurate nicotine delivery is crucial for both consumer satisfaction and regulatory compliance,” he says. “There is a growing demand for solutions that help users manage and reduce their nicotine intake effectively.”
Age-Gating is Key
Progress will be driven not only by hardware developments but also by the characteristics of nicotine. “Certain clean technologies such as synthetic nicotine could further reduce risk and improve delivery,” says Newns. “We are already seeing this rolled out in markets across the world. We believe that such development can only be a positive thing if the developments are carried out from a scientific point of view. That is, keeping in mind the nicotine user’s journey from cigarettes to safer alternatives, complying with regulation and placing responsibility to the customer and environment front of mind.”
Wang expects novel nicotine particulates to enhance the speed and efficiency of nicotine delivery, building on the foundation laid by innovations like nicotine salts. “Nicotine salts improved the speed of delivery and provided a stronger throat hit, closely mimicking the experience of smoking combustible cigarettes,” he says. “This similarity, along with the availability of various flavors, greatly contributed to the success and adoption of reduced-risk products.”
According to Wang, the success of flavors in helping smokers transition to e-cigarettes underscores the importance of continuing to develop advanced nicotine-delivery systems that provide a satisfying and effective alternative to traditional tobacco products.
Preventing underage access to nicotine products will remain an important objective for manufacturers. To ensure its products never get into the hands of minors, Puff Store rolled out MyChekr, a technology that uses artificial intelligence to estimate the ages of would-be buyers (see “Beyond Face Value,” Tobacco Reporter, December 2023). The system is being adopted by a growing number of companies.
Ispire Technologies offers an age-verification system that uses a combination of Bluetooth and blockchain technology. “This system employs biometric verification, ensuring that only authorized users can access the devices, thus preventing underage usage effectively,” says Wang. “The integration of blockchain technology sets our solution apart from the competition by offering an unparalleled level of security and transparency. Blockchain’s immutable nature ensures that all age-verification data is securely stored and cannot be tampered with, providing a trustworthy system for both consumers and regulators. The use of Bluetooth enables a seamless and efficient user experience, making our age-gating technology not only secure but also highly accessible and convenient for users.”
Transitioning to Reusables
Meanwhile, disposable e-cigarettes face an uncertain future due to environmental concerns, with some markets banning the entire category and others considering restrictions. “Although the U.S. may not see immediate FDA [Food and Drug Administration] mandates on disposables, the long-term trend will likely favor pod systems and reusable products, significantly reducing e-waste and aligning with environmental sustainability goals,” says Wang. “We are confident that disposable vapes will either disappear altogether or become a smaller player in the market over time. While disposables are incredibly convenient, their environmental impact is prompting a shift toward more sustainable options. Moving forward, we anticipate a greater emphasis on devices with removable batteries and the adoption of pod systems to reduce waste.”
Newns believes that vaping companies have a responsibility to ensure that new regulatory restrictions, such as a ban of disposable vapes, do not prevent adult smokers from transitioning to safer alternatives. “We also know that disposable vapes, given the products’ convenience and price point, are vital for many adult smokers in the initial phase of the switch from cigarettes,” he says. “We hope to see regulation as a driving force for new technology and innovation to allow safer products to be developed with better inhalation techniques and quality.”
With this in mind, he says, Plxsur remains focused on supporting customers to migrate from disposables to pod-based systems. “We have worked closely with our partner companies to put commercial strategies in place to achieve this,” says Newns. “For example, in Q4 last year, Puff, the number one vaping company in Italy and part of Plxsur, successfully migrated many of its customers to pod and open devices, with these alternative products now outperforming disposable devices by volume for the company. As we remain focused on our responsibility to reduce our environmental impact, we continue to see such efforts on migration across the group.”
