ENDS Industry Whitepaper 2026: Compliance, Costs, True Puff & Market Shifts

Executive Summary: The Authority vs. Commodity Paradox

The global Electronic Nicotine Delivery Systems (ENDS) sector currently stands at a precarious inflection point, defined by a structural tension we identify as the Authority vs. Commodity Paradox. On one vector, the market has been inundated by the rapid proliferation of "Fast Moving Consumer Goods" (FMCG) in the form of high-capacity disposable vaporization devices. These products, characterized by their plastic chassis and increasingly aggressive marketing claims, have commoditized the nicotine delivery experience. Manufacturers now engage in a quantitative "arms race," advertising puff counts ranging from 25,000 to 50,000 per unit—figures that frequently defy the fundamental laws of thermodynamics, fluid dynamics, and battery capacity benchmarks.1

On the opposing vector lies a rigid, increasingly fragmented regulatory architecture. From the U.S. Food and Drug Administration's (FDA) rigorous Premarket Tobacco Product Application (PMTA) pathway to the European Union's pending TPD3 revision, the compliance burden has shifted from administrative oversight to pharmaceutical-grade validation. This regulatory tightening targets the very "marketing hyperbole" that drives current sales volumes, creating a regulatory chasm that threatens the viability of non-compliant enterprises.

This white paper posits that the resolution to this paradox lies in the operationalization of Truth. In an industry historically categorized under "Vice," the most valuable currency is no longer novelty, but Trust—specifically, trust derived from quantifiable, calculable, and scientifically valid data. By pivoting from a transactional retail model to one of an "Educated Middleman," stakeholders can leverage high-fidelity "Calculation Assets"—algorithmic engines rooted in pharmacokinetics, ISO testing standards, and macroeconomic tax analysis—to bridge the gap between consumer skepticism and regulatory expectation.

Section 1: The Regulatory Architecture and Compliance Matrices

The regulatory environment for ENDS is no longer a monolith but a complex, multi-jurisdictional matrix. Understanding the distinct compliance architectures of the United States, the European Union, and emerging markets is a prerequisite for any entity seeking institutional authority.

1.1 The United States: The PMTA Pathway and the "Appropriate for the Protection of Public Health" (APPH) Standard

The U.S. regulatory framework is anchored by the Family Smoking Prevention and Tobacco Control Act, specifically the requirement that all new tobacco products must receive a Marketing Granted Order (MGO) from the FDA. The statutory standard for this authorization is that the product must be "Appropriate for the Protection of Public Health" (APPH)—a rigorous benchmark that requires applicants to demonstrate that the product's benefit to adult smokers (switching) outweighs the risk to youth (initiation).3

1.1.1 The Authorized Product Landscape (2025)

As of December 29, 2025, the FDA has issued MGOs for 39 e-cigarette products.3 This list represents the entirety of the federally authorized ENDS market, a stark contrast to the thousands of unauthorized disposable products currently available at retail. The authorized portfolio is highly consolidated among four major manufacturers: JUUL Labs Inc., NJOY LLC, R.J. Reynolds (Vuse), and Logic Technology Development LLC.3

The notable absence of open-system e-liquids and fruit/dessert flavors from this list underscores the FDA's de facto ban on non-tobacco flavors in cartridge-based systems, a policy enforced to curb youth appeal.

1.1.2 The "Chain of Risk" and Nicotine Pouch Authorizations

In a significant regulatory shift, the FDA has introduced a "Chain of Risk" framework, acknowledging a continuum of harm where combustible cigarettes pose the highest risk and non-combustible products pose lower risks.5 This framework was operationalized with the historic January 2025 authorization of 20 ZYN nicotine pouch products and the subsequent December 2025 authorization of six on! PLUS products.6

These authorizations are critical precedents. They demonstrate that the FDA will authorize flavored products (Mint, Wintergreen, Smooth, etc.) if the applicant provides robust pharmacokinetic (PK) and abuse liability data showing that the products do not pose an undue risk of youth initiation while providing a viable switching pathway for adult smokers.6 The approval of on! PLUS was notably expedited under a new PMTA pilot program designed to streamline review efficiencies for products with established safety profiles.7

1.1.3 State-Level Bifurcation: PMTA Registries and Flavor Bans

While federal enforcement focuses on manufacturers, individual states have enacted legislation targeting the point of sale. A growing number of states, including Alabama, Louisiana, Oklahoma, and Wisconsin, have passed "PMTA Registry" laws.8 These statutes require manufacturers to certify that their products have either received an MGO or have a PMTA pending substantive review to be listed on a state directory. Products not listed cannot be legally sold, effectively purging the market of "grey market" disposables.

Additionally, Texas enacted SB 2024, effective September 1, 2025, which bans Chinese-manufactured disposable vapes and imposes strict packaging restrictions to eliminate youth-appealing imagery.9

In California, the enforcement of the flavor ban (SB 793) and subsequent strengthening measures (AB 3218) has led to a measurable impact. Post-implementation data from 2023-2024 indicates a 36.98% reduction in total e-cigarette nicotine sales and a 10.55% reduction in cigarette pack sales.10 However, the market has seen a rise in "non-menthol cooling" agents (synthetic coolants) to circumvent these restrictions.10

1.2 The European Union: The TPD3 Horizon

The European market currently operates under the Tobacco Products Directive (TPD) 2014/40/EU, specifically Article 20, which imposes strict technical ceilings:

• Nicotine Cap: Maximum
  $$20 \text{ mg/ml}$$
  (2.0%).11
• Volume Cap: Maximum
  $$2 \text{ ml}$$for tanks/disposables and$$10 \text{ ml}$$
  for refill containers.11

1.2.1 The Pending TPD3 Revision

The European Commission is drafting the third revision of the TPD (TPD3). Leaked drafts and committee discussions from late 2025 suggest a push toward:

• Nicotine Pouch Regulation: A potential total ban on nicotine pouches across the EU is being considered, or at minimum, strict flavor bans and nicotine caps.12 France has already moved unilaterally to ban nicotine pouches effective February 2025.14
• Taxation Harmonization: A revision of the Tobacco Taxation Directive (adopted as a proposal in July 2025) aims to introduce EU-wide minimum excise duties on new products, including e-cigarettes and pouches, to reduce price disparities across Member States.15

1.3 The United Kingdom, New Zealand, and Australia: The Ban Paradigms

• United Kingdom: The UK government has announced a ban on the sale and supply of single-use (disposable) vapes effective June 1, 2025.16 This legislation mandates that all legal devices must be rechargeable and refillable, aiming to mitigate the environmental disaster of lithium-ion battery waste.16
• New Zealand: A ban on disposable vapes came into force on June 17, 2025.17 New regulations also prohibit the display of vaping products in general retail stores and restrict flavor names to generic descriptors.18
• Australia: Australia has implemented the strictest model globally. As of July 1, 2024, the sale of vapes outside of pharmacies is illegal. From October 1, 2024, therapeutic vapes with nicotine concentrations of
  $$20 \text{ mg/ml}$$
  or less can be sold by pharmacists without a prescription (Schedule 3), subject to consultation. Higher strengths require a prescription.19

Section 2: Thermophysics and Stoichiometry of Nicotine Delivery

The efficacy of an ENDS product—its ability to transition a smoker away from combustible tobacco—is fundamentally a function of physics and chemistry. It relies on the precise stoichiometry of nicotine salts and the thermodynamics of aerosol generation.

2.1 Nicotine Stoichiometry: The Acid-Base Equilibrium

The "innovation" that catalyzed the modern vaping era is the protonation of nicotine. Freebase nicotine (

$$C_{10}H_{14}N_2$$
) is alkaline (

$$pK_{a} \approx 8.0$$
), causing significant pharyngeal irritation ("throat hit") at high concentrations. By reacting freebase nicotine with an organic acid, manufacturers create a nicotine salt, lowering the pH to a tolerable range (5.0–6.5) and enabling high-strength formulations (up to 50 mg/ml).21

2.1.1 Nicotine Benzoate Formation

Nicotine benzoate (

$$C_{10}H_{14}N_2 \cdot C_7H_6O_2$$
) is the industry standard. It is synthesized via the reaction of nicotine with benzoic acid.

Reaction Stoichiometry:

$$C_{10}H_{14}N_2 + C_7H_6O_2 \rightarrow C_{10}H_{14}N_2H^+ + C_7H_5O_2^-$$
Using molar masses:

• $$M_{\text{Nicotine}} \approx 162.23 \text{ g/mol}$$
  .23
• $$M_{\text{Benzoic Acid}} \approx 122.12 \text{ g/mol}$$
  .
• $$M_{\text{Nicotine Benzoate}} \approx 284.35 \text{ g/mol}$$
  .24

To achieve a stoichiometric 1:1 salt, the mass ratio required is:

$$\frac{122.12 \text{ g (Acid)}}{162.23 \text{ g (Base)}} \approx 0.753$$

Thus, for every 1 gram of nicotine, approximately 0.753 grams of benzoic acid is required to fully protonate the solution.25

2.1.2 Alternative Salt Formulations

• Nicotine Salicylate (
  $$C_{10}H_{14}N_2 \cdot C_7H_6O_3$$
  ): Formed with salicylic acid (
  $$M \approx 138.12 \text{ g/mol}$$
  ). Known for a smoother throat hit and lower oxidative stress in aerosol emissions due to the antioxidant properties of the salicylate moiety.26
• Nicotine Levulinate (
  $$C_{10}H_{14}N_2 \cdot C_5H_8O_3$$
  ): Formed with levulinic acid (
  $$M \approx 116.11 \text{ g/mol}$$
  ). Historically used by the tobacco industry, levulinic acid enhances nicotine binding efficiency.28

2.2 Systemic Nicotine Delivery (SND) and Nicotine Flux

To compare products accurately, we must move beyond "content" (what is in the device) to "delivery" (what reaches the bloodstream) and the rate of that delivery.

Nicotine Flux Formula (

$$J_{nic}$$
):
Shihadeh and Eissenberg defined Nicotine Flux as the rate of nicotine emission per second 29:

$$J_{nic} (\mu g/s) = \frac{Y_{puff}}{D_{puff}} \times 1000$$
Where:

• $$Y_{puff}$$
  = Nicotine yield per puff (mg/puff).
• $$D_{puff}$$
  = Puff duration (seconds).

Systemic Nicotine Delivery (SND):

$$SND = D_{content} \times Bio_{rate}$$
Table 2: Comparative Pharmacokinetics of Nicotine Delivery Systems

Scientific Context Notice: All pharmacokinetic values presented in this section are derived from population-level laboratory studies conducted under controlled experimental conditions. These values do not represent individual exposure, health outcomes, or personalized risk. They must not be interpreted as medical advice, treatment guidance, or product performance guarantees.

Insight: High-flux ENDS (e.g., 180

$$\mu g/s$$
) can mimic the pharmacokinetic spike of a cigarette, making them effective for switching but also raising abuse liability concerns.31

2.3 The "True Puff" Standard: Debunking the 25,000 Puff Myth

The most pervasive marketing distortion in the industry is the "Puff Count." To address this, we apply the True Puff (

$$P_{real}$$
) validity verifier using ISO standards.

True Puff Formula:

$$P_{real} = \frac{V_{liq} \times 1000}{C_{puff}}$$

• $$V_{liq}$$
  : E-liquid volume (ml).
• $$C_{puff}$$
  : Liquid consumption per puff ($\mu L$ or mg).

Hardware Variables (

$$C_{puff}$$
):

• ISO 20768 Standard: Defines a puff as 55 ml volume over 3 seconds.32
• Standard Wire Coil (1.2$\Omega$): Consumes ~2-3 mg per puff.4
• Dual Mesh Coil / Boost Mode: Consumes 5-10 mg per puff.4

Calculation Case Study: The "25,000 Puff" Disposable
Consider a popular device like the Geek Bar Pulse X, advertised as "25,000 Puffs" with an 18 ml capacity.33

• $$V_{liq} = 18 \text{ ml}$$
  *
  $$C_{puff} \text{ (Pulse Mode)} \approx 7.0 \text{ mg} \text{ (approx. } 6.0 \mu L)$$

$$P_{real \text{ (Pulse)}} = \frac{18 \times 1000}{6.0} \approx 3,000 \text{ Scientific Puffs}$$
Conclusion: The advertised "25,000 puffs" assumes a "Marketing Puff" duration of < 0.5 seconds. The True Puff count, based on the physics of vaporization and ISO 20768 standards, is approximately 12% to 15% of the marketing claim.

Section 3: Material Science and Environmental Impact

The shift toward disposables has transformed the industry into a linear waste economy. Analyzing the material flow reveals significant environmental liabilities.

3.1 Device Deconstruction and Elemental Analysis

A 2024 study by the University of Plymouth deconstructed contemporary disposables, revealing a complex assembly of over 21 distinct components.4

Table 3: Disposable Vape Material Composition (Median Mass: ~50g)

3.2 The Lithium Economy and Battery Costs

Each disposable contains a lithium-ion battery. With 1.3 million to 5 million disposables thrown away weekly in the UK alone 35, this represents a massive loss of critical minerals.

• Lithium Waste: UK disposable waste equates to 10 tonnes of lithium annually, enough for 1,200 EV batteries.37
• Battery Economics: Lithium-ion battery pack prices have fallen significantly, reaching a record low of $108/kWh in 2025.38 This price drop lowers the manufacturing barrier for high-capacity disposables, fueling the "puff count arms race" despite environmental costs.

3.3 Hydrometallurgical Recycling Efficiency

Recycling these devices is complex. However, advanced hydrometallurgical recycling processes (using aqueous chemistry to leach metals) can achieve recovery rates of >98% for Cobalt, Nickel, and Lithium.40 This method reduces greenhouse gas emissions by 37.7% compared to pyrometallurgy.40

---

Section 4: Economic Analysis and Market Dynamics

For the consumer, the decision to switch from smoking to vaping is often driven by economics. We quantify this using the Annualized Differential Cost (ADC) model.

4.1 Annualized Differential Cost (ADC) Model

$$S_{annual} = (C_{cig} \times Q_{cigs} \times 365) - \left( \frac{Q_{cigs} \times N_{cig\_yield} \times 365}{N_{vape\_eff}} \times C_{vape\_unit} \right)$$

• $$C_{cig}$$
  (Cost per Pack): Highly variable by jurisdiction.
  • New York (High Tax): ~$14.55 (State Tax $5.35 + NYC Tax $1.50).41
  • Missouri (Low Tax): ~$6.11 (State Tax $0.17).42
• $$Q_{cigs}$$
  : Packs per day (Assumption: 1 pack/day).
• $$N_{cig\_yield}$$
  : Bioavailable nicotine per pack (~22 mg).
• $$N_{vape\_eff}$$
  : Bioavailable nicotine per device (~600 mg for a 20ml / 5% device, adjusted for
  $$Bio_{rate}$$
  ).
• $$C_{vape\_unit}$$
  : Retail price of disposable (~$20.00).

Calculation: New York Smoker (1 Pack/Day)

• Cost of Smoking:
  $$14.55 \times 365 = \$5,310.75$$
• Cost of Vaping:
  • Annual Nicotine Demand:
    $$22 \text{ mg} \times 365 = 8,030 \text{ mg}$$
    * Devices Needed:
    $$8,030 / 600 \approx 13.4 \text{ devices}$$
    * Annual Vape Cost:
    $$13.4 \times \$20.00 = \$268.00$$
• Annual Savings (
  $$S_{annual}$$
  ): ~$5,042.75

Insight: Even in low-tax states like Missouri, the savings are substantial (~$1,960/year). However, proposed federal tax increases in 2025 could alter this equation by taxing vape products at rates comparable to cigarettes.43

Compliance Notice: This economic model is provided solely for the purpose of analyzing cost structures between different nicotine delivery systems. It does not constitute health advice, product endorsement, or encouragement of use. Economic cost differences must not be interpreted as indicators of safety, suitability, or health benefit. Regulatory status, legality, and accessibility of nicotine products vary significantly by jurisdiction.

4.2 Youth Usage Trends (2024 Data)

The 2024 National Youth Tobacco Survey (NYTS) reveals shifting brand preferences.

• Overall Use: 5.9% of students reported vaping in 2024, down from 7.7% in 2023.44
• Brand Shift: Elf Bar usage dropped significantly to 36.1% (from 56.7% in 2023) due to FDA enforcement, while Breeze (19.9%) and Mr. Fog (15.8%) gained traction.44
• Flavors: 87.6% of youth users prefer flavored products, primarily Fruit (62.8%) and Candy (33.3%).44

---

Section 5: Future Outlook and Technological Innovation (2025-2030)

The industry is pivoting away from simple resistive heating toward advanced material sciences and smart technologies.

5.1 Ultrasonic Atomization: The "Coil-Less" Future

Emerging brands like Surge Vapor and Lost Mary (Ultrasonic 35K) are deploying piezoelectric ultrasonic technology. Instead of heat, an ultrasonic chip vibrates at 3 million times per second to cavitate the e-liquid into an aerosol.45

• Advantages: Eliminates "dry hits" (no burning cotton), reduces thermal degradation of terpenes/flavors, and operates at lower temperatures, potentially reducing toxin emission.46
• Market Impact: This technology addresses the "burnt taste" reliability issue inherent in high-capacity disposables.

5.2 Ceramic Coil Evolution: FEELM Max

FEELM Max technology utilizes a microporous ceramic substrate rather than a cotton wick.

• Efficiency: Improves e-liquid utilization by 30%, yielding more puffs per ml compared to mesh coils.47
• Purity: Reduces aerosol impurities by 78%.47

5.3 Smart Screens and AI Integration

Devices like the Geek Bar Pulse X and Raz DC25000 now feature "Mega HD" screens.33 These interfaces not only display battery/liquid levels but also use AI to manage power curves (VPU chips) for consistent flavor delivery, marking the transition of vapes from simple circuits to smart consumer electronics.

Conclusion

The ENDS industry has graduated from a chaotic disruptive force to a mature sector governed by the rigorous principles of Chemical Stoichiometry, Fluid Dynamics, and Regulatory Compliance. The "Authority vs. Commodity" paradox is resolved not by louder marketing, but by deeper data.

For stakeholders—whether retailers, manufacturers, or regulators—success in 2025 and beyond requires a mastery of the Risk, Environmental, and Operational lenses detailed in this report. By anchoring operations in the mathematical realities of the True Puff, the Annualized Differential Cost, and the Systemic Nicotine Delivery models, the industry can build a resilient, ethical, and transparent framework that aligns commercial objectives with the imperative of public health.
