Effects of Electronic Cigarettes and NRT on CVD in Smokers
Smoking is a major risk factor for many health conditions, including cancer and CVD. Electronic cigarettes may help smokers quit.

Smoking is a major risk factor for many health conditions, including lung cancer and cardiovascular disease (CVD). Although nicotine replacement therapy (NRT) and behavioral encouragement are the most effective ways to quit smoking, the high relapse rate indicates the need to reconsider smoking cessation strategies.


For example, 27% of smokers interested in quitting use electronic cigarette products, while 18% use NRT. However, evidence regarding the impact of electronic cigarettes on cardiovascular health is limited. Therefore, this randomized controlled trial aims to compare the CVD outcomes of smokers randomly assigned to receive nicotine-containing electronic cigarettes, nicotine-free electronic cigarettes, or NRT treatment at 3 and 6 month follow-ups.


A study conducted on a group of 248 individuals who smoked at least 10 cigarettes a day and aimed to quit smoking measured cardiovascular disease (CVD) outcomes such as flow-mediated dilation (FMD), mean arterial pressure (MAP), and skin microvascular responses to acetylcholine (ACh) and nitroprusside (SNP). The study found that all three groups demonstrated improvement in FMD at 3 months (β=3.33, 95%CI 2.61-4.05, p = 0.0001) and 6 months (β=2.69, 95%CI 2.02-3.35, p < 0.0001). However, there were no significant differences in other CVD outcomes such as skin microvascular responses to ACh and SNP, and MAP between the three treatment groups. Overall, the study concludes that quitting smoking leads to improved CVD outcomes at 3 and 6 months, but there is no significant difference in improvement between the treatment groups.

Special Report|From CrossBar 20K to 6-Methyl Nicotine KUMI: Two Routes Into U.S. State Vape Directories?
Several U.S. states have incorporated the September 9, 2020 PMTA filing deadline into eligibility rules for certain vaping products. CrossBar 20K drew attention after appearing on Pennsylvania's 163-entry directory. A broader 2Firsts investigation found that related registration businesses also listed KUMI and CROSSBAR SIX products, with 171 KUMI-related entries across Louisiana, Nebraska and Wisconsin. Corporate records link Scott Silverman to Blue Nine LLC and VR Products I LLC. PMTA compliance expert Mr. K said historical applications and nicotine-analogue products may offer two different approaches to state-directory access.

FDA Revises Import Alert 98-07 Rules, Bringing May Enforcement Priorities Into Unauthorized ENDS Detentions
FDA Revises Import Alert 98-07 Rules, Bringing May Enforcement Priorities Into Unauthorized ENDS Detentions
The U.S. Food and Drug Administration has revised the rules under Import Alert 98-07 to incorporate its May 2026 enforcement-priority policy for certain electronic nicotine delivery systems marketed without premarket authorization. The alert continues to allow detention without physical examination, or DWPE, for ENDS lacking required marketing authorization, while directing field divisions to apply the May risk-based framework. When necessary, detention or refusal decisions must also undergo review by the FDA's Center for Tobacco Products. Products including PACHA and Vuse Pro have already emerged as industry examples of the May policy, although enforcement discretion does not constitute FDA marketing authorization.

GSTHR Estimates 200 Million People Use Non-Combustible Nicotine Products as 28 Countries Show Rising Use Alongside Falling Smoking Rates
The Global State of Tobacco Harm Reduction, a project operated by Knowledge·Action·Change, estimates that about 200 million people worldwide use non-combustible nicotine products including vapes, heated tobacco, nicotine pouches and snus. Its 2026 report says use of these products rose alongside declining smoking rates in 28 countries it analyzed. The data do not establish that all 200 million users have quit smoking, nor do they prove a direct causal relationship. GSTHR also says regulatory restrictions on the products continue to expand in many markets.
