    Studies Show: Switching From Cigarettes To Vape May Be Better For Heart Health

    Although E-Cigs have been getting a lot of attention recently for their popularity among kids and the recent illicit THC cartridge lung injuries, many have also looked to vaping as a less harmful alternative to smoking traditional cigarettes. On Friday, the Journal of the American College of Cardiology published new research suggesting that heart health among adult smokers’ could benefit from switching over to e-cigarettes.  The study consisted of 114 people and concluded that vaping e-cigarettes improved blood vessel health, and could be seen in “vascular stiffness” within just a month of making the switch from traditional cigarettes. “The ability of our blood vessels to widen and increase flow when needed has been linked to long-term outcomes,” explained Dr. Rose Marie Robertson, deputy chief science and medical officer for the American Heart Association. The study which states that people who switched over to e-cigarettes full time and those who had smoked cigarettes for less than 20 years, saw much more rapid results in improving their vascular function.  In addition, there was another study conducted at the University of Dundee in the United Kingdom where they had some new findings. Existing studies had suggested that vaping increased cardiovascular risks, for example finding certain compounds in e-cigarettes that were thought to have damaged cardiovascular cells and that vaping after just one use could change blood vessels. “The [new study’s] finding contradicts the findings of observational studies that find that people who vape are at higher risk of heart disease, because those studies are inevitably and irreversibly confounded by former smoking,” said John Britton, director of the UK Centre for Tobacco and Alcohol Studies.  In conclusion, all recent reports have shown that vaping is much more healthy than previously thought. Even though vaping is still a safer alternative to smoking, it should still be used responsibly.

  2. What Will PHE Do With The Vaping Situation In The Us

    What Will PHE Do With The Vaping Situation In The Us

    Since mid-September, headlines around the world have warned about an outbreak of serious lung disease across the US, said to be associated with vaping. As of October 22, 1,604 cases have been reported to the Center for Disease Control (CDC) from 49 US states, including 34 deaths.   Dr Dana Meaney-Delman, head of the CDC team investigating the outbreak has reported that “We've narrowed this clearly to THC-containing products that are associated with most patients who are experiencing lung injury. The specific substance or substances we have not identified yet”. THC is the main psychoactive component of cannabis and the CDC has said that the products identified are being obtained off the street or from other informal sources. The specific chemical or chemicals that are causing the illness and deaths have not yet been identified and it is not clear that all cases are the same kind of injury. The outbreak does not appear to be associated with long term use of nicotine e-cigarettes, which have been used in the US for over 10 years.  the responses we have seen to the problem in the US and in other countries may increase the already widespread misunderstanding about the relative safety of nicotine e-cigarettes, deterring smokers from switching and risk driving vapers who have switched back to smoking. There is a real risk therefore that such a reaction will mean people continue to smoke, which will undoubtedly put lives at risk. PHE’s advice on e-cigarettes remains the same PHE has not changed its advice on nicotine containing e-cigarettes: Smokers should consider switching completely and vapers should stop smoking.

  3. Study In UK Finds Vaping Is Good For The Heart

    Study In UK Finds Vaping Is Good For The Heart

    Smokers can improve the health of their hearts within weeks of switching to e-cigarettes, the largest trial of its kind shows. The month-long study of 114 smokers suggests vaping has the potential to reduce heart attack and stroke risk.  The British Heart Foundation said stopping smoking was the single best thing you could do for your heart.  Chemical substances in cigarette smoke slim arteries since they get furred with greasy deposits increasing the risk of a fatal blockage. Ultimately smoking cigarettes doubles your risk of using a heart attack.  But the researchers mentioned the present evidence on vaping was "poor" and quite often examined the impact of any individual e-cigarette on cardiovascular system wellness.  So that they supervised people's bloodstream a month when they had been switched to e-cigs in the test.  They focused on how blood vessels increase whenever a wave of bloodstream rushes through, by calculating "stream-mediated dilation".  The more the bloodstream are able to broaden the much healthier they may be. Stream-mediate dilation ratings have already been closely linked to the long-term probability of heart attacks and stroke. The results, published in the Journal of the American College of Cardiology, showed: Healthy non-smokers had a score of 7.7percent Smokers had a score of 5.5percent But those who switched to nicotine e-cigarettes for a month had a score of 6.7percent So, switching to vaping got those smokers about halfway back to a healthy score. "They're not quite normal, but their vascular function improved quite significantly, just within a month," said one of the researchers, Professor Jacob George.  Prof John Britton, director of the UK centre for tobacco and alcohol studies at the University of Nottingham, said: "This randomised trial provides clear evidence of a reduction in a marker of cardiovascular disease risk in people who switch from smoking to vaping. "The finding of the study, that vaping is less harmful than smoking, is intuitively correct on the grounds of the lower range and levels of emissions known to be present in vapour relative to tobacco smoke."   The resources: https://www.bbc.com/news/health-50436296

  4. Vitamin E Acetate In Illegal E-Cigarette Is To Blame

    Vitamin E Acetate In Illegal E-Cigarette Is To Blame

    The centers for disease control and prevention (CDC) eventually all but acknowledged that e-cigarette deaths and lung disease had nothing to do with legal nicotine e-cigarettes. "For the first time, we have identified a potential toxin of concern in a patient's biological sample, vitamin E acetate," Dr. Anne Schuchat, the CDC's lead deputy director, said today. The CDC examined lung tissue samples from 29 patients in 10 states and found that all contained vitamin E acetate oil. "These new findings are significant," Schuchat said. "We have a powerful criminal." Legal e-cigarettes do not contain vitamin E acetate. But it is often used by drug dealers to cut THC vape bullets to increase their profits. "These findings provide direct evidence for the role of vitamin E acetate in major lung injury sites," Schuchat said. Given that e-cigarettes have been around for more than a decade, have tens of millions of users around the world, and have never had an outbreak of such a disease, the CDC should be clear that there is something more at work than nicotine. While e-cigarettes are ubiquitous in places like Canada and Europe, it should be especially clear that the United States is the only country in the world to have an e-cigarette epidemic. But the CDC insists that common e-cigarettes cannot be ruled out as a cause of the outbreak. As recently as November 1, the centers for disease control and prevention advised that "people should consider avoiding all e-cigarette or vaping products during the investigation because the specific compounds or ingredients causing lung damage are not known." "The national campaign for tobacco-free children and the Truth Initiative, the best-funded anti-tobacco group, have been highlighting the crisis, without mentioning THC or the black market. The centers for disease control and prevention (CDC) has been reluctant to give any recognition to e-cigarettes as a useful tool for smokers trying to quit and has not clarified to the public that e-cigarette use of legal nicotine products is highly unlikely to cause e-cigarette-related deaths and lung disease.

  5. Smoke Rings Tutorial : How To Do it

    Smoke Rings Tutorial : How To Do it

    There are many people in our life who are vaping. It is also very cool to be able to spit out a series of the shaped circle. So many people want to see how to smoke the smoke rings. Following our step to learn how to make the smoke rings.   Method 1 first. take a deep vaping, do not immediately swallow or spit, let the smoke in your mouth mixing, the mouth made "oh" sound, the front of the tongue outward with force to push the mouth of smoke, after pushing a tongue quickly back, then push a general a smoke can spit 3-4 complete circle ring.   Method 2 take a deep vaping, inhale smoke enough, pay attention not to the lungs, but to allow smoke to stay in the throat, and then back into O type, type O more standard, spit out the smoke turn more standard, has remained until finish vomit to form a loop and smoke turn, finally with the tongue flicking the tooth, the tongue bounces your teeth, bend your tongue down, and let the smoke out.   Push the ring with one hand   Some players have a slow hand cut during practice, possibly because they are afraid of breaking the smoke ring, which may cause the smoke ring to not move fast enough. some of them are too fast, which causes the smoke circle to be pushed off when a shot is taken. When practicing, you can push slowly and feel the speed of hand cutting. At the same time, pay attention to the distance of 5CM from the smoke ring. Once the feeling of pushing the ring is right, you can slightly accelerate the speed of the hand-cut, and finally, make the cough circle push the circle instead of seeing the circle push circle.   Push the ring with both hands   When pushing the ring with both hands, the palm of the hand gives the force of the smoke ring. and the fingers control the flight path of the smoke ring. After the first step is pushed down, keep the palm parallel to the shoulder, and then slowly push forward.

  6. Proof: E-Cigarettes Reduce CO Emissions Compared To Cigarette

    Proof: E-Cigarettes Reduce CO Emissions Compared To Cigarette

    Carbon monoxide is produced when cigarettes burn. When carbon monoxide is inhaled, it combines with hemoglobin, producing carboxyhemoglobin, which greatly diminishes hemoglobin’s oxygen-carrying capacity. As a result, small amounts of carbon monoxide can dramatically reduce hemoglobin’s ability to transport oxygen. Common symptoms of carbon monoxide exposure are headache, nausea, rapid breathing, weakness, exhaustion, dizziness, and confusion. Hypoxia due to acute carbon monoxide poisoning may result in reversible neurological effects, or it may result in long-term irreversible brain damage or heart damage effects. So cigarettes increase the risk of heart disease. Cigarette smoke releases several toxic chemicals and carcinogens including carbon monoxide CO. This study examined the levels of exhaled CO in smokers switching to electronic cigarettes e-Cigs or a tobacco heating system THS and their level of compliance six months after switching.  40 male smokers unwilling or unable to stop smoking were switched to e-Cigs or THSs for six months. Nicotine addiction and levels of carbon monoxide in the exhaled breath eCO were measured. after six months. The two groups showed no difference, but a significant higher addiction score in smokers choosing THS. E-Cig and THS showed significant reduced levels of eCO after six months, which were within the range of non-smoker status. The THS group had a significantly lower reduction in levels of CO vs the e-Cig group.  Both e-Cigs and THSs are capable of significantly reducing eCO at least in the medium term, hence constituting a viable tobacco harm reduction approach in smokers who are unwilling or unable to stop smoking. references:https://www.ncbi.nlm.nih.gov/pubmed/31618949

  7. Effects Of E-Cigarettes On Allergic Airway Disease

    Effects Of E-Cigarettes On Allergic Airway Disease

    Effects Of E-Cigarettes On Allergic Airway Disease Flavored e-cigarettes are preferred by the majority of users yet their potential toxicity is unknown. Therefore our aim was to determine the effect of selected flavored e-cigarettes, with or without nicotine, on allergic airways disease in mice. To determine if any effects were due to nicotine, we compared the effects of flavored e-cigarettes with and without nicotine at 12mg/ML. Mice were exposed to indoor air and e-cigarette fumes twice a day for 30 minutes, six days a week. Effect of e-cigarette exposure on weight The effect of e-cigarette exposure on weight gain was assessed by measuring weight on Day 21 before the assessment of lung function. There was no effect of HDM on weight in female or male mice exposed to the e-cigarette with or without nicotine. male mice exposed to PG/VG with nicotine had reduced weight compared to Room Air exposed mice. Effect of e-cigarette exposure on HDM-induced airway inflammation e-cigarettes without nicotine macrophages were increased in HDM mice exposed Black Licorice compared to Room Air, with a trend towards increased total leukocytes. PG/VG, Kola or Banana Pudding did not alter total leukocytes, eosinophils or macrophages. there was no difference in neutrophils between HDM mice exposed to Room Air and those exposed to any of the nicotine-free e-cigarettes. This suggests that flavored e-cigarettes without nicotine have variable effects on airway inflammation during allergic airways disease, with the direction of the effect and the type of inflammatory cells affected dependent upon the specific flavor.  e-cigarettes with nicotine all e-cigarettes containing 12 mg/mL nicotine dampened airway inflammation. Compared to HDM mice exposed to Room Air, mice exposed to PG/VG and all flavored e-cigarettes had reduced total leukocytes, eosinophils, and macrophages. the present findings suggest that the effect of flavored e-cigarettes without nicotine on HDM-induced airway inflammation is dependent upon the specific flavor. In contrast, nicotine universally suppressed airway inflammation regardless of the flavor. Effect of e-cigarettes on HDM-induced airway hyperresponsiveness In mice exposed to e-cigarettes without nicotine or with nicotine, HDM treatment increased AHR as measured by Rrs, Ers, Rn, G, and H, There was no difference between HDM treated mice exposed to Room Air and any of the e-cigarette exposures as measured by Rrs, Ers, Rn. Effect of e-cigarette exposure on HDM-induced airway remodeling In mice exposed to nicotine-free e-cigarettes, HDM treatment increased soluble content. In mice exposed to 12 mg/mL nicotine, soluble lung collagen was increased with HDM treatment but there was no difference between mice exposed to Room Air and any of the e-cigarettes. Summary there was a consistent suppression of airway inflammation without any effect on AHR or airway remodeling due to e-cigarettes with nicotine, regardless of the flavor. Flavored e-cigarettes without nicotine had significant but heterogeneous effects on features of allergic airways disease. This suggests that some flavored e-cigarettes may alter asthma pathophysiology even when used without nicotine. Reference:https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6754426/

  8. Comparison:E-Cigarettes And Nicotine Replacement Therapy

    Comparison:E-Cigarettes And Nicotine Replacement Therapy

    The objective was to compare the efficacy of refillable e-cigarettes and nicotine replacement therapy NRT products, when accompanied by weekly behavioural support. The NRT arm n = 446 received NRT of their choice, provided for up to 12 weeks. The e-cigarette arm n = 438 received an e-cigarette starter pack and were encouraged to buy addtional e-liquids and e-cigarette products of their choice.  RESULTS  The 1-year quit rate was 9.9percent in the NRT arm and 18.0percent in the e-cigarette arm. The e-cigarette arm had significantly higher validated quit rates at all time points. Participants in the e-cigarette arm showed significantly better adherence and experienced fewer urges to smoke throughout the initial 4 weeks of their quit attempt than those in the NRT arm, and gave their allocated product more favourable ratings. Participants assigned to e-cigarettes reported significantly less coughing and phlegm at 1 year than those assigned to NRT. CONCLUSIONS Within the context of multisession treatment for smokers seeking help, e-cigarettes were significantly more effective than NRT, Can be considered as an aid to smoking cessation.

  9. Dependence Comparison: E-Cigarettes, Nicotine Gum And Tobacco Cigarettes

    Dependence Comparison: E-Cigarettes, Nicotine Gum And Tobacco Cigarettes

    Dependence comparison: e-cigarettes, nicotine gum and tobacco cigarettes   To assess dependence levels in users of e-cigarettes, and compare them with dependence levels in users of nicotine gums and tobacco cigarettes. Self-reports from cross-sectional Internet and mail surveys. Comparisons of: a. 766 daily users of nicotine-containing e-cigarettes with 30 daily users of nicotine-free e-cigarettes; b. 911 former smokers who used the e-cigarette daily with 451 former smokers who used the nicotine gum daily; c. 125 daily e-cigarette users who smoked daily with two samples of daily smokers who did not use e-cigarettes. Comparison of levels of dependence when vaping vs smoking In the 911 former smokers who used e-cigarettes daily, 74percentage rated their current dependence on e-cigarettes as “weaker” than their prior dependence on tobacco cigarettes, 21percentage as “same” and 3percentage as “stronger”. These 911 exclusive e-cigarette users reported that when they were smoking tobacco cigarettes, they smoked their first cigarette 23 minutes after waking, whereas they currently took their first puff on their e-cigarette 32 minutes after waking. Exclusive e-cigarette users rated their previous dependence on tobacco cigarettes at 90 on a scale of 0-100, whereas they rated their current dependence on e-cigarettes at 64. Among the 125 daily smokers daily dual users, 62percentage rated their current dependence on e-cigarettes as “weaker” than their current dependence on tobacco cigarettes, 28percentage as “same” and 3percentage as “stronger”. These dual users reported that they currently smoked 11.7 cigarettes per day, compared to 23.3 cigarettes per day before they started to use e-cigarettes. comparison of e-cigarette users dual users vs other smokers In daily smokers, vapers dual users rated their dependence on e-cigarettes lower 44.9 on a scale of 0 to 100 than smokers rated their dependence on tobacco cigarettes 68.6 to 84.5 on a scale of 0 to 100. comparison of users of e-cigarette vs nicotine gum In the subsample of short-term users of these products, there were few differences in dependence ratings between e-cigarette users and gum users. Results Dependence ratings were slightly higher in users of nicotine-containing e-cigarettes than in users of nicotine-free e-cigarettes. In former smokers, long-term users of e-cigarettes were less dependent on e-cigarettes than long-term users of the nicotine gum were dependent on the gum. Dependence on e-cigarettes was generally lower in dual users than dependence on tobacco cigarettes in the two other samples of daily smokers. Some e-cigarette users were dependent on nicotine-containing e-cigarettes, but these products were less addictive than tobacco cigarettes. E-cigarettes may be as or less addictive than nicotine gums, which themselves are not very addictive.

  10. Study The Dependence Of Smoking And Vaping On Nicotine

    Study The Dependence Of Smoking And Vaping On Nicotine

    Study the dependence of smoking and vaping on nicotine.   American Indian population has the highest percentage of smoking and EC use in the United States, focusing on the dual user subset, defined as people who smoked cigarettes and used ECs on some days or every day of the past 30 days. Study the dependence of cigarettes on dual users.   About two-thirds used a tanking product. Eleven percent used ECs without nicotine and another 9percentage were unsure of the nicotine content. A minority 40percentage enjoyed vaping more than smoking, and most 76percentage would smoke first on days they did both. Thirty-one percent vaped within 5 min of walking and another 24percentage within 30 min. Although the two-item heaviness of use index did not differ significantly between smoking and vaping, the ten-item Penn State Dependence Index PSDI suggested greater dependence on smoking than vaping 11.02 vs. 6.42, respectively; p less than .0001. The most common reasons for vaping were to reduce smoking 79percentage, enjoyment of flavors 78percentage, and the ability to vape where smoking is not allowed 73percentage. Perceptions of less harm to others 69percentage or to self were the next most common 65percentage. Fewer than half used ECs to reduce stress, for affordability, or because others used them. Individual measures show more dependence on smoking than vaping. The heaviness of vaping index and heaviness of smoking index did not differ significantly among the dual users p equal 0.22, but the mean PSDI dependence score for vaping was significantly lower than that for smoking 6.4−4.8 vs 11.0−5.0, respectively; p less than 0001. Results were unchanged when median values of the PSDI were compared via the Wilcoxon signed-rank test 6 vs 11, p less than.0001. The top three most commonly endorsed reasons for vaping were to cut down on smoking, liking EC flavors, and being able to vape in places wherein smoking is not allowed. Perceiving less harm to others or to oneself compared with smoking were the next most frequent responses. Less than one-half endorsed using EC to reduce stress, reduce cost, or because other persons important to them used EC. Other reasons write in for EC use were endorsed by only two 4.5percentage participants.   Results Nearly 20percentage of dual users used ECs either without nicotine or without knowing if the product containing nicotine. The PSDI indicated greater dependence on smoking than vaping. Reasons for vaping were nearly equal between smoking reduction and enjoying flavors.    References: https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-019-7523-5#Fig1
