India accounts for nearly two-thirds of chewing tobacco users worldwide, with stroke and oral cancers being the leading health harms. https://vapeindia.org/science/2027-impact-of-non-tobacco-nicotine-products-on-postoperative-outcomes-in-soft-tissue/ https://vapeindia.org/science/2027-impact-of-non-tobacco-nicotine-products-on-postoperative-outcomes-in-soft-tissue/ Fri, 01 Jan 2027 00:00:00 GMT Researchers examined hand surgery patients and found that those using non-tobacco nicotine products (like e-cigarettes and nicotine pouches) in the year before surgery experienced higher rates of wound complications, blood clots, and infections after their procedures compared to non-users. https://vapeindia.org/science/2027-nicotine-and-tobacco-product-use-among-us-youth-in-10th-and-12th-grade-2023-2025/ https://vapeindia.org/science/2027-nicotine-and-tobacco-product-use-among-us-youth-in-10th-and-12th-grade-2023-2025/ Fri, 01 Jan 2027 00:00:00 GMT A US study tracking tobacco and nicotine use among high school students from 2023-2025 found that nicotine pouches are emerging as a growing concern, more than doubling in use over two years, while traditional cigarette smoking remained at historic lows. Most other nicotine products showed stable or unchanged use patterns, though many young users consumed multiple products simultaneously. https://vapeindia.org/science/2026-a-qualitative-assessment-of-oral-nicotine-pouch-use-topography/ https://vapeindia.org/science/2026-a-qualitative-assessment-of-oral-nicotine-pouch-use-topography/ Thu, 01 Jan 2026 00:00:00 GMT Researchers interviewed 44 regular oral nicotine pouch users to understand how they use these products. Users reported varying habits including where they place pouches in their mouth, how long they keep them in, and whether they use multiple pouches at once—all of which affect how much nicotine they absorb. https://vapeindia.org/science/2026-addressing-challenges-in-reviewing-e-cigarette-evidence-proposing-a-new-test-for/ https://vapeindia.org/science/2026-addressing-challenges-in-reviewing-e-cigarette-evidence-proposing-a-new-test-for/ Thu, 01 Jan 2026 00:00:00 GMT Researchers found that when reviewing evidence on e-cigarettes for quitting smoking, one large study (Hajek et al.) overwhelmingly influenced the overall conclusion, potentially distorting the true picture. They propose a new testing method to detect when single studies unfairly dominate systematic reviews, helping policymakers better understand the actual strength of evidence. https://vapeindia.org/science/2026-adolescent-use-of-nicotine-pouches-in-four-latin-american-countries-a-cross-sect/ https://vapeindia.org/science/2026-adolescent-use-of-nicotine-pouches-in-four-latin-american-countries-a-cross-sect/ Thu, 01 Jan 2026 00:00:00 GMT A survey of nearly 13,000 adolescents across four Latin American countries found that about 6% had tried nicotine pouches, with current use at 2.4%. Pouches were more popular in Peru than Argentina, appealed more to boys and wealthier teens, and were often obtained informally through friends rather than direct purchase. https://vapeindia.org/science/2026-adolescents-are-less-likely-to-attempt-to-quit-cannabis-than-tobacco-the-potenti/ https://vapeindia.org/science/2026-adolescents-are-less-likely-to-attempt-to-quit-cannabis-than-tobacco-the-potenti/ Thu, 01 Jan 2026 00:00:00 GMT A study of over 25,000 California adolescents found that fewer young people attempt to stop using cannabis (39%) compared to vaping (53%) or smoking cigarettes (48%). The lower quit-attempt rate for cannabis may be linked to young people viewing it as less risky than tobacco products. https://vapeindia.org/science/2026-affective-reactivity-to-a-remote-computer-based-trier-social-stress-test-during-/ https://vapeindia.org/science/2026-affective-reactivity-to-a-remote-computer-based-trier-social-stress-test-during-/ Thu, 01 Jan 2026 00:00:00 GMT When smokers trying to quit experience heightened anxiety during a stressful task while already deprived of nicotine, they are more likely to smoke cigarettes and relapse within 48 hours. The study suggests that measuring anxiety responses might help identify smokers at higher risk of early failure in quit attempts. https://vapeindia.org/science/2026-an-evaluation-of-anxiety-and-depressive-symptoms-in-terms-of-smoking-among-black/ https://vapeindia.org/science/2026-an-evaluation-of-anxiety-and-depressive-symptoms-in-terms-of-smoking-among-black/ Thu, 01 Jan 2026 00:00:00 GMT This study examined 498 Black daily smokers and found that anxiety and depression together—and sometimes independently—influence various smoking behaviors including difficulty quitting, dependence severity, and expectations about withdrawal symptoms. The combination of these two mental health conditions appears particularly important in understanding why some smokers struggle to quit. https://vapeindia.org/science/2026-anticipated-behavioural-responses-to-potential-regulatory-actions-to-reduce-nico/ https://vapeindia.org/science/2026-anticipated-behavioural-responses-to-potential-regulatory-actions-to-reduce-nico/ Thu, 01 Jan 2026 00:00:00 GMT Researchers surveyed smokers across four countries to understand how people might change their smoking behaviour if governments reduced nicotine in cigarettes to non-addictive levels. The study found that smokers anticipated various responses, including smoking more cigarettes, switching to other nicotine products, or quitting entirely. https://vapeindia.org/science/2026-assessment-of-heavy-metal-contamination-and-source-apportionment-in-smokeless-to/ https://vapeindia.org/science/2026-assessment-of-heavy-metal-contamination-and-source-apportionment-in-smokeless-to/ Thu, 01 Jan 2026 00:00:00 GMT Researchers found concerning levels of heavy metals like arsenic, lead, and chromium in smokeless tobacco products sold across India, with samples from Uttar Pradesh showing the highest contamination. While non-cancer risks appeared low, cancer risks from these metals—especially for regular users—were moderate to concerning and warrant urgent regulatory action. https://vapeindia.org/science/2026-association-between-perceived-relative-harm-of-electronic-cigarettes-versus-ciga/ https://vapeindia.org/science/2026-association-between-perceived-relative-harm-of-electronic-cigarettes-versus-ciga/ Thu, 01 Jan 2026 00:00:00 GMT When young adults believed e-cigarettes were as harmful as regular cigarettes, some quit nicotine products altogether, but others switched to combustible cigarettes or alternative tobacco products. This suggests that simply warning people about e-cigarette risks may not reduce overall tobacco use and could unintentionally push users toward more harmful alternatives. https://vapeindia.org/science/2026-association-of-smoking-reduction-with-comorbid-psychiatric-symptoms-including-ad/ https://vapeindia.org/science/2026-association-of-smoking-reduction-with-comorbid-psychiatric-symptoms-including-ad/ Thu, 01 Jan 2026 00:00:00 GMT A French study of 68 smokers found that those with childhood ADHD symptoms and higher impulsivity were more likely to fail at quitting or reducing smoking. Depression was also linked to poor smoking reduction outcomes. The researchers suggest that screening and treating ADHD and impulsivity early could improve quit rates. https://vapeindia.org/science/2026-associations-of-exclusive-e-cigarette-use-and-dual-use-of-e-cigarettes-and-combu/ https://vapeindia.org/science/2026-associations-of-exclusive-e-cigarette-use-and-dual-use-of-e-cigarettes-and-combu/ Thu, 01 Jan 2026 00:00:00 GMT Researchers analyzed studies comparing e-cigarette use and hypertension risk. Using e-cigarettes alone showed no clear link to high blood pressure, but people using both e-cigarettes and regular cigarettes had higher hypertension risk. Traditional cigarette smoking remained clearly associated with high blood pressure. https://vapeindia.org/science/2026-associations-of-motivation-to-quit-smoking-or-vaping-quitting-self-efficacy-and-/ https://vapeindia.org/science/2026-associations-of-motivation-to-quit-smoking-or-vaping-quitting-self-efficacy-and-/ Thu, 01 Jan 2026 00:00:00 GMT A study of 700 American smokers and vapers found that people using oral nicotine pouches tend to have lower motivation to quit smoking or vaping. Interestingly, among smokers, those who had attempted quitting more frequently used nicotine pouches more often, while among vapers, greater confidence in quitting was linked to higher pouch use. https://vapeindia.org/science/2026-baseline-quitting-self-efficacy-as-a-predictor-of-duration-of-vaping-abstinence-/ https://vapeindia.org/science/2026-baseline-quitting-self-efficacy-as-a-predictor-of-duration-of-vaping-abstinence-/ Thu, 01 Jan 2026 00:00:00 GMT A study of 389 people using a vaping cessation app found that those who started with greater confidence in their ability to quit vaping stayed abstinent about 2 days longer than those with low confidence. People with higher confidence were also significantly less likely to relapse within the first week. https://vapeindia.org/science/2026-beliefs-about-non-cigarette-tobacco-products-for-cigarette-smoking-cessation-amo/ https://vapeindia.org/science/2026-beliefs-about-non-cigarette-tobacco-products-for-cigarette-smoking-cessation-amo/ Thu, 01 Jan 2026 00:00:00 GMT A U.S. survey found that most adults are uncertain whether non-cigarette tobacco products help smokers quit, while about one in five believe they can help. People who had previously used e-cigarettes or other modified tobacco products were significantly more likely to believe these products aid cessation. https://vapeindia.org/science/2026-beliefs-about-the-relative-harmfulness-of-electronic-cigarettes-compared-with-ci/ https://vapeindia.org/science/2026-beliefs-about-the-relative-harmfulness-of-electronic-cigarettes-compared-with-ci/ Thu, 01 Jan 2026 00:00:00 GMT A survey of Israeli adults found widespread confusion about e-cigarette harms: only 29% correctly understood e-cigarettes as less harmful than regular cigarettes, while over half believed they were equally or more harmful. Smokers and older adults were especially likely to overestimate e-cigarette dangers, suggesting public health communication about relative risks has been ineffective. https://vapeindia.org/science/2026-cancer-screening-adherence-in-the-united-states-by-smoking-and-vaping-status-202/ https://vapeindia.org/science/2026-cancer-screening-adherence-in-the-united-states-by-smoking-and-vaping-status-202/ Thu, 01 Jan 2026 00:00:00 GMT A US study found that cigarette smokers are significantly less likely to get screened for colorectal, breast, cervical, and prostate cancers compared to non-smokers. Vaping showed mixed associations with screening rates that differed by gender and smoking history, but smoking remained the strongest barrier to cancer screening across all types. https://vapeindia.org/science/2026-cannabis-co-use-and-endocannabinoid-system-modulation-in-tobacco-use-disorder/ https://vapeindia.org/science/2026-cannabis-co-use-and-endocannabinoid-system-modulation-in-tobacco-use-disorder/ Thu, 01 Jan 2026 00:00:00 GMT Research shows that people who use both tobacco and cannabis are 25% less likely to quit smoking. However, a specific cannabis compound called CBD showed promise in reducing cigarette use by 40% and easing withdrawal symptoms, suggesting targeted cannabis-based treatments could help tobacco cessation. https://vapeindia.org/science/2026-cannabis-craving-and-cross-substance-substitution-during-cannabis-treatment-init/ https://vapeindia.org/science/2026-cannabis-craving-and-cross-substance-substitution-during-cannabis-treatment-init/ Thu, 01 Jan 2026 00:00:00 GMT When people reduce cannabis use, they may drink slightly more alcohol, especially if they experience cannabis cravings. However, cigarette smoking showed mixed patterns—sometimes increasing and sometimes decreasing with cannabis reduction. Medical treatments did not substantially change these substitution patterns. https://vapeindia.org/science/2026-changes-in-gambling-behaviour-and-harm-across-the-adult-population-among-priorit/ https://vapeindia.org/science/2026-changes-in-gambling-behaviour-and-harm-across-the-adult-population-among-priorit/ Thu, 01 Jan 2026 00:00:00 GMT A British survey tracking adults from 2021-2024 found gambling activity and related harms increased significantly, with daily gambling rates rising from 1.1% to 1.7% and treatment for gambling disorder doubling from 0.9% to 1.6%. People exceeding alcohol guidelines and cannabis users showed highest gambling rates, suggesting overlapping addiction vulnerabilities. https://vapeindia.org/science/2026-changes-in-human-biomarkers-of-exposure-after-complete-switching-from-cigarettes/ https://vapeindia.org/science/2026-changes-in-human-biomarkers-of-exposure-after-complete-switching-from-cigarettes/ Thu, 01 Jan 2026 00:00:00 GMT Researchers analyzed 60 studies and found that people who completely switched from cigarettes to e-cigarettes showed substantially reduced levels of harmful toxins in their bodies—reductions ranging from 61% to 92% depending on the specific toxin measured. However, the authors emphasize these findings show reduced exposure to measured toxins, not proof of reduced disease risk or long-term safety. https://vapeindia.org/science/2026-changes-in-preferred-e-cigarette-flavor-nicotine-concentration-wattage-and-air-v/ https://vapeindia.org/science/2026-changes-in-preferred-e-cigarette-flavor-nicotine-concentration-wattage-and-air-v/ Thu, 01 Jan 2026 00:00:00 GMT When smokers tried switching to e-cigarettes over 12 weeks, their cigarette consumption dropped by about 10 cigarettes daily. Users consistently preferred fruity flavors and specific nicotine strengths based on device type, with these preferences remaining stable throughout the study. https://vapeindia.org/science/2026-cigarette-smoke-and-e-cigarette-aerosol-extracts-induce-myelopoiesis-and-suppres/ https://vapeindia.org/science/2026-cigarette-smoke-and-e-cigarette-aerosol-extracts-induce-myelopoiesis-and-suppres/ Thu, 01 Jan 2026 00:00:00 GMT Laboratory research comparing cigarette smoke and e-cigarette vapor found both substances reduce the immune system's ability to fight infections and inflammation, while causing lasting changes to bone marrow cells that increase production of certain white blood cells. These changes persisted even after exposure stopped, suggesting potential long-term health consequences. https://vapeindia.org/science/2026-cigarette-smoking-trends-among-persons-with-psychiatric-disorders-1999-2026/ https://vapeindia.org/science/2026-cigarette-smoking-trends-among-persons-with-psychiatric-disorders-1999-2026/ Thu, 01 Jan 2026 00:00:00 GMT Between 1999 and 2026, smoking rates declined significantly among the general US population and people with bipolar disorder or depression, but remained unchanged for those with schizophrenia. However, all groups—including those with schizophrenia—smoked fewer cigarettes daily over time. https://vapeindia.org/science/2026-codevelopment-implementation-and-evaluation-of-an-ai-powered-conversational-inte/ https://vapeindia.org/science/2026-codevelopment-implementation-and-evaluation-of-an-ai-powered-conversational-inte/ Thu, 01 Jan 2026 00:00:00 GMT Researchers developed and tested a computer-based conversational tool (powered by artificial intelligence) designed to help people quit tobacco. The study followed a single group of participants before and after using this interface to assess whether it could support tobacco cessation efforts. https://vapeindia.org/science/2026-combination-bupropion-zonisamide-facilitates-rapid-reduction-in-smoke-exposure-a/ https://vapeindia.org/science/2026-combination-bupropion-zonisamide-facilitates-rapid-reduction-in-smoke-exposure-a/ Thu, 01 Jan 2026 00:00:00 GMT A medication combination of bupropion and zonisamide helped people who smoke cigarettes switch to e-cigarettes more successfully than either drug alone or placebo, with faster initial reductions in smoking and weight loss instead of weight gain. https://vapeindia.org/science/2026-communicating-the-nicotine-and-tobacco-risk-continuum-a-scoping-review-and-frame/ https://vapeindia.org/science/2026-communicating-the-nicotine-and-tobacco-risk-continuum-a-scoping-review-and-frame/ Thu, 01 Jan 2026 00:00:00 GMT Researchers examined how health messages about different nicotine and tobacco products compare in effectiveness. While messages helped people better understand the relative risks of lower-risk products, the way these messages were designed and delivered varied widely across studies, creating confusion about whether people should switch products entirely. https://vapeindia.org/science/2026-comparative-burden-and-projections-of-chewing-tobacco-attributable-lip-oral-cavi/ https://vapeindia.org/science/2026-comparative-burden-and-projections-of-chewing-tobacco-attributable-lip-oral-cavi/ Thu, 01 Jan 2026 00:00:00 GMT Chewing tobacco is causing an increasing burden of lip, oral cavity, and esophageal cancers globally and especially in China between 2000-2021. While oral cancer cases are projected to keep rising (particularly in men), esophageal cancer cases are declining. Population growth and aging are the main drivers of these trends. https://vapeindia.org/science/2026-cultural-drivers-modes-of-use-and-perceived-harms-of-traditional-and-non-traditi/ https://vapeindia.org/science/2026-cultural-drivers-modes-of-use-and-perceived-harms-of-traditional-and-non-traditi/ Thu, 01 Jan 2026 00:00:00 GMT Smokeless tobacco use in South Africa is driven by cultural, spiritual, and medicinal beliefs rather than just recreation. Users experience real health harms, but some believe spiritual practices protect them from danger, which may prevent them from quitting. https://vapeindia.org/science/2026-daily-patterns-of-opioid-and-stimulant-use-and-associated-risk-behavior-outcomes/ https://vapeindia.org/science/2026-daily-patterns-of-opioid-and-stimulant-use-and-associated-risk-behavior-outcomes/ Thu, 01 Jan 2026 00:00:00 GMT Researchers tracked daily drug use patterns in 87 people over two weeks and found that on days when people used opioids together with stimulants, they were more likely to engage in risky behaviors like injecting drugs or using other substances compared to days when they used opioids alone. https://vapeindia.org/science/2026-e-cigarette-and-nicotine-pouch-use-among-youth-united-states-2025/ https://vapeindia.org/science/2026-e-cigarette-and-nicotine-pouch-use-among-youth-united-states-2025/ Thu, 01 Jan 2026 00:00:00 GMT A 2025 U.S. survey found that e-cigarettes remain the most popular tobacco product among youth, with nicotine pouches rising as a secondary choice. Nearly all young users preferred flavored versions—particularly fruit flavors for e-cigarettes and mint for pouches—with Geek Bar and ZYN emerging as the dominant brands. https://vapeindia.org/science/2026-e-cigarette-heated-tobacco-and-cigarette-preferences-among-canadian-e-cigarette-/ https://vapeindia.org/science/2026-e-cigarette-heated-tobacco-and-cigarette-preferences-among-canadian-e-cigarette-/ Thu, 01 Jan 2026 00:00:00 GMT Canadian researchers found that on-product health warnings significantly discourage people from choosing e-cigarettes, heated tobacco, or cigarettes, with the effect strongest when warnings appear on all three product types simultaneously. Higher prices also reduced product preference, while lower nicotine concentrations in vape products were favored by both users and non-users. https://vapeindia.org/science/2026-e-cigarette-perceptions-among-adults-with-recent-myocardial-infarction-or-heart-/ https://vapeindia.org/science/2026-e-cigarette-perceptions-among-adults-with-recent-myocardial-infarction-or-heart-/ Thu, 01 Jan 2026 00:00:00 GMT A US study found that people who recently suffered heart attacks or heart failure showed little interest in switching from regular cigarettes to e-cigarettes, with only 4.5% expressing willingness to make the switch. Most participants (70%) believed e-cigarettes were very or extremely harmful, suggesting e-cigarette switching is unlikely to be an effective smoking reduction strategy for this high-risk cardiac population. https://vapeindia.org/science/2026-e-cigarette-puffs-per-day-and-changes-in-cigarettes-per-day-among-combustible-ci/ https://vapeindia.org/science/2026-e-cigarette-puffs-per-day-and-changes-in-cigarettes-per-day-among-combustible-ci/ Thu, 01 Jan 2026 00:00:00 GMT Among people with opioid use disorder who smoke, those who successfully reduced their cigarette consumption by at least half showed a distinctive pattern: they increased their e-cigarette use early on and maintained higher usage levels throughout a 4-week trial. Those who failed to reduce cigarettes showed stable or declining e-cigarette use, suggesting that adequate e-cigarette adoption may be necessary for switching away from combustible cigarettes in this population. https://vapeindia.org/science/2026-e-cigarettes-for-harm-reduction-among-copd-patients-who-smoke-a-pilot-investigat/ https://vapeindia.org/science/2026-e-cigarettes-for-harm-reduction-among-copd-patients-who-smoke-a-pilot-investigat/ Thu, 01 Jan 2026 00:00:00 GMT In a small pilot study, about half of COPD patients who smoke were able to reduce their cigarette consumption by at least 50% by switching to e-cigarettes over 12 weeks. Those who successfully switched showed measurable improvements in carbon monoxide levels and breathing-related quality of life scores, though other health improvements were more modest. https://vapeindia.org/science/2026-e-cigarettes-with-and-without-behavioral-support-for-smoking-cessation/ https://vapeindia.org/science/2026-e-cigarettes-with-and-without-behavioral-support-for-smoking-cessation/ Thu, 01 Jan 2026 00:00:00 GMT A clinical trial found that e-cigarettes alone helped smokers quit at nearly twice the rate of email support messages alone (11.3% vs 6.4%), and adding phone-based behavioral counseling to e-cigarettes doubled quit rates further (21.1%). This suggests e-cigarettes can be effective smoking cessation tools, especially when combined with professional support. https://vapeindia.org/science/2026-effect-of-a-collaborative-intervention-by-pharmacists-and-dentists-on-smoking-ce/ https://vapeindia.org/science/2026-effect-of-a-collaborative-intervention-by-pharmacists-and-dentists-on-smoking-ce/ Thu, 01 Jan 2026 00:00:00 GMT When pharmacists and dentists worked together to help smokers quit using counseling, nicotine replacement therapy, and digital follow-up, about a quarter achieved complete abstinence and another fifth cut their smoking in half within six months. Adding nicotine replacement therapy to counseling produced significantly better results than counseling alone. https://vapeindia.org/science/2026-effect-of-flavored-on-nicotine-pouch-products-on-smoking-behaviors-a-sequential-/ https://vapeindia.org/science/2026-effect-of-flavored-on-nicotine-pouch-products-on-smoking-behaviors-a-sequential-/ Thu, 01 Jan 2026 00:00:00 GMT This study tested whether nicotine pouches with flavors help people reduce cigarette smoking compared to unflavored versions. Both flavored and unflavored pouches helped smokers cut cigarette use by about half, though flavors may help non-responders and create more smoke-free days initially. https://vapeindia.org/science/2026-effectiveness-of-digital-therapy-added-to-the-usual-intervention-for-smoking-ces/ https://vapeindia.org/science/2026-effectiveness-of-digital-therapy-added-to-the-usual-intervention-for-smoking-ces/ Thu, 01 Jan 2026 00:00:00 GMT When doctors combined standard smoking cessation counseling with a digital therapy app, patients achieved higher quit rates and reduced cigarette use more than those receiving standard care alone. At 6 months, 50% of those using the digital tool had quit smoking compared to 36% with standard care only. https://vapeindia.org/science/2026-effects-of-china-s-e-cigarette-administration-measures-on-users-a-mixed-methods-/ https://vapeindia.org/science/2026-effects-of-china-s-e-cigarette-administration-measures-on-users-a-mixed-methods-/ Thu, 01 Jan 2026 00:00:00 GMT When China restricted e-cigarette flavours and online sales in 2022, most users continued accessing products through illegal channels. While some users quit, others increased consumption, and many believed remaining products were safer due to misleading labelling. The regulations achieved limited public health gains. https://vapeindia.org/science/2026-emergency-department-management-of-nicotine-use-a-white-paper-prepared-for-the-a/ https://vapeindia.org/science/2026-emergency-department-management-of-nicotine-use-a-white-paper-prepared-for-the-a/ Thu, 01 Jan 2026 00:00:00 GMT Emergency department doctors should screen all patients for nicotine addiction and offer evidence-based medications plus counseling before discharge, with referrals to ongoing treatment. This approach can help reduce serious health harms from nicotine use. https://vapeindia.org/science/2026-etiological-trends-defect-classification-and-prosthetic-rehabilitation-of-maxill/ https://vapeindia.org/science/2026-etiological-trends-defect-classification-and-prosthetic-rehabilitation-of-maxill/ Thu, 01 Jan 2026 00:00:00 GMT This study examined 246 patients treated for facial and jaw defects over nine years at an Indian hospital.

The law also showed signs of encouraging some young people to quit nicotine use entirely, though this effect was less conclusive. https://vapeindia.org/science/2026-frequent-mental-distress-associations-with-nicotine-use-behaviors/ https://vapeindia.org/science/2026-frequent-mental-distress-associations-with-nicotine-use-behaviors/ Thu, 01 Jan 2026 00:00:00 GMT Adults experiencing frequent mental distress are significantly more likely to use nicotine products, including cigarettes and e-cigarettes, compared to those without mental distress. Notably, people with mental distress who smoke are also more motivated to quit, suggesting they may be responsive to cessation support. https://vapeindia.org/science/2026-future-time-perspective-and-vaping-initiation-among-adults-who-smoke-findings-fr/ https://vapeindia.org/science/2026-future-time-perspective-and-vaping-initiation-among-adults-who-smoke-findings-fr/ Thu, 01 Jan 2026 00:00:00 GMT Smokers aged over 55 who think about long-term consequences were nearly four times more likely to try vaping. People who believed vaping was less harmful than smoking were also significantly more likely to start vaping, regardless of age or how they thought about the future. https://vapeindia.org/science/2026-global-burden-of-lip-and-oral-cavity-cancer-attributed-to-different-tobacco-use-/ https://vapeindia.org/science/2026-global-burden-of-lip-and-oral-cavity-cancer-attributed-to-different-tobacco-use-/ Thu, 01 Jan 2026 00:00:00 GMT Global research from 1990-2021 shows that while smoking-related mouth and lip cancer deaths have declined worldwide due to tobacco control efforts, cancer deaths from chewing tobacco have remained stubbornly high and are projected to stay that way through 2050. South Asia carries the heaviest burden, with women particularly affected by chewing tobacco. https://vapeindia.org/science/2026-guideline-no-470-nicotine-and-pregnancy/ https://vapeindia.org/science/2026-guideline-no-470-nicotine-and-pregnancy/ Thu, 01 Jan 2026 00:00:00 GMT A Canadian medical guideline recommends that pregnant women and those planning pregnancy be routinely screened for nicotine use from any source. The guideline advises behavioral counseling as the primary approach, with careful consideration of nicotine replacement or other medicines when needed, plus ongoing support after delivery to prevent relapse. https://vapeindia.org/science/2026-healthcare-providers-are-less-likely-to-ask-about-and-advise-cessation-for-non-c/ https://vapeindia.org/science/2026-healthcare-providers-are-less-likely-to-ask-about-and-advise-cessation-for-non-c/ Thu, 01 Jan 2026 00:00:00 GMT A large US survey found that doctors ask cigarette smokers about their tobacco use more often than users of cigars, smokeless tobacco, or e-cigarettes. When doctors do ask non-cigarette users about tobacco, they are far less likely to recommend quitting compared to cigarette smokers. https://vapeindia.org/science/2026-heated-tobacco-product-awareness-and-use-among-young-adult-texas-college-student/ https://vapeindia.org/science/2026-heated-tobacco-product-awareness-and-use-among-young-adult-texas-college-student/ Thu, 01 Jan 2026 00:00:00 GMT Among nearly 18,000 Texas college students in 2025-2026, awareness of heated tobacco products remained low at 15%, with only 2.5% reporting ever trying them and 0.6% using them in the past month. Use was concentrated among young adults already using other tobacco products, particularly e-cigarettes, with no evidence the products were being adopted for quitting smoking. https://vapeindia.org/science/2026-heavy-metals-in-nicotine-containing-products-sources-exposure-and-health-risks/ https://vapeindia.org/science/2026-heavy-metals-in-nicotine-containing-products-sources-exposure-and-health-risks/ Thu, 01 Jan 2026 00:00:00 GMT Researchers found that both traditional cigarettes and newer nicotine products like e-cigarettes, snus, and nicotine pouches contain dangerous heavy metals including mercury, lead, cadmium, and arsenic. While alternative products may reduce some smoking-related harms, users still face significant exposure to these toxic metals. Better monitoring and stricter regulations are needed across all nicotine products. https://vapeindia.org/science/2026-high-content-screening-comparison-of-1r6f-cigarette-smoke-extract-and-selected-h/ https://vapeindia.org/science/2026-high-content-screening-comparison-of-1r6f-cigarette-smoke-extract-and-selected-h/ Thu, 01 Jan 2026 00:00:00 GMT Laboratory testing of cell samples exposed to cigarette smoke, heated tobacco products, and e-cigarette vapour showed that cigarette smoke caused the most damage to cells and DNA, while the heated tobacco and e-cigarette products produced less damage under these specific test conditions. However, the researchers note these lab findings do not prove these products are safer for human health. https://vapeindia.org/science/2026-hybrid-human-digital-motivational-incentive-intervention-protocol-for-smoking-ce/ https://vapeindia.org/science/2026-hybrid-human-digital-motivational-incentive-intervention-protocol-for-smoking-ce/ Thu, 01 Jan 2026 00:00:00 GMT Researchers designed a program combining human coaching with mobile app technology and incentive rewards to help pregnant women on Medicaid quit smoking. The program tested whether offering gift cards for engagement and abstinence, paired with digital tools and phone support, could be practical and acceptable for this population. https://vapeindia.org/science/2026-illicitly-traded-tobacco-use-among-samples-of-people-who-regularly-use-illegal-d/ https://vapeindia.org/science/2026-illicitly-traded-tobacco-use-among-samples-of-people-who-regularly-use-illegal-d/ Thu, 01 Jan 2026 00:00:00 GMT Among people who regularly use illegal drugs in Australia, the use of illegally traded tobacco nearly doubled between 2024-2025, with affordability as the main driver. Illegal tobacco was typically purchased from tobacconists, and use was more common in Sydney than other major cities. https://vapeindia.org/science/2026-impact-of-increased-funding-for-stop-smoking-services-in-england-on-quit-attempt/ https://vapeindia.org/science/2026-impact-of-increased-funding-for-stop-smoking-services-in-england-on-quit-attempt/ Thu, 01 Jan 2026 00:00:00 GMT Between 2021-2025, England increased public funding for smoking cessation support services. This population-based study examined whether higher funding levels led to more people attempting to quit smoking during this period.
