Switching to vaping improves COPD patients

Study: COPD Patients Improve After Switching to Vaping

Chronic obstructive pulmonary disease (COPD) is intricately linked to smoking. It’s estimated around 80% of cases of COPD are caused by smoking, and it’s one of the most important ways smoking causes death and disease. It might not be the first smoking-related condition you think of, but it’s right up there with lung cancer and heart disease as one of the major risks of smoking.


With all of this in mind, the impact of vaping on COPD risk and the effect of switching on smokers with COPD are two crucial areas for research to look at. A new study from Professor Riccardo Polosa and his team does just that, covering a massive three years of data from a group of smokers with COPD who switched to vaping, and comparing their results with smokers who didn’t switch. The researchers found that vaping “may reverse some of the harm resulting from tobacco smoking in COPD patients.” For smokers interested in making the switch to vaping, the study offers more excellent news.


What is COPD?


COPD is a broad term that covers many different specific conditions, including emphysema, bronchitis and non-reversible asthma. Doctors group the conditions together because they are all progressive lung diseases. This means you increasingly struggle to breathe as the condition progresses. Most sufferers are over 40 years old and have a history of smoking, and it’s estimated to affect about one in five smokers. As the condition progresses, sufferers may struggle to perform simple tasks like climbing a flight of stairs or walking to the mailbox without feeling breathless and exhausted. COPD is currently incurable and it is the third leading cause of death in the US. The World Health Organization estimates that it will also be the third leading cause of death worldwide by 2030.


Presently, the only strategy to reduce the impact of COPD and improve the prognosis of sufferers is to stop smoking. However, many COPD sufferers struggle to quit, and this is why the researchers investigated the potential impact of vaping: it could be a pragmatic solution to the problem, although likely not an absolutely ideal one.


The Study: What They Did

The researchers recruited two groups of smokers. One group consisted of 22 smokers with COPD who switched to vaping at the start of the study period. The researchers matched these smokers with another group of 22 smokers who didn’t switch to vaping, so they could compare their results to see if vaping had an impact on their conditions. The smokers were followed up with each year for a total of three years, with the results from the first two years first being reported a couple of years ago in a separate study.


What They Found: COPD Sufferers Who Switched to Vaping Saw Improvements

The researchers looked at several indicators of how the patients were progressing at each follow-up visit. These included their relevant symptoms, the number of cigarettes they smoked per day, the number of serious exacerbations of their condition (requiring treatment or a hospital visit) in the past year, standard lung function tests, their scores on a COPD health questionnaire and (for patients who agreed and were able to) the distance they could walk in six minutes. If these measures improved (for example, fewer exacerbations and a longer walking distance), this signifies an improvement in their COPD.


Vaping Helps COPD Sufferers Smoke Less Per Day


Firstly, the researchers noted a substantial reduction in the number of cigarettes smoked per day in the COPD sufferers who started vaping. At the first visit, they smoked an average of 22 cigarettes per day, which fell to just 2 per day after a year and continued to drop to an average of 1.5 per day by the third year. At the three-year mark, 13 of the 22 smokers who started vaping had completely quit smoking. In contrast, the control group continued to smoke the same number of cigarettes per day throughout the study.


COPD Sufferers Who Switched Had Fewer Exacerbations of Their Condition


The patients with COPD who switched to vaping had significantly fewer exacerbations of their condition at each of the three follow-up visits. The number of exacerbations declined from an average of 2.3 at the first visit to 1.3 at the three-year follow-up, which was a statistically significant improvement. In comparison, the control group saw no reductions in exacerbations, despite being at a similar rate of 2.1 at the beginning of the study. The difference between the groups at the end of the study was statistically significant. Notably, the vapers who also continued to smoke (dual users) also saw a significant decrease in their number of exacerbations over the three-year period.


Switchers Improved on COPD Questionnaire and Six Minute Walking Distance


The scores on the COPD questionnaire also significantly improved for the group who switched to vaping. In comparison, there was no improvement in the control group. By the third visit, the switching group’s score had improved by 5.5 points on the questionnaire, from around 20 to 15, compared to the control group scores, which remained at around 20 throughout. Again, both the dual users and the full switchers showed consistent improvements.


Scores on the six minute walking distance test weren’t available for all participants, but there was a significant difference between the groups after three years. For the switchers, their walking distance improved by a median of 70 meters, but for the control group the distance actually decreased by 7.5 meters.


Is Vaping a Good Harm Reduction Strategy for COPD Patients?


The overall results of the study suggest plenty of benefits for smokers with COPD who switch to vaping. While the researchers didn’t see an improvement on lung function tests, they took the fact that their conditions didn’t get worse as a positive sign. Many advanced COPD patients continue to suffer reduced lung function like this. This is often true even if they quit smoking and remain completely abstinent from all forms of nicotine.


The remainder of the measures investigated in the study did show improvements. The researchers point to the reduction in exposure to carbon monoxide as the cause for this. Experts expect improvements in these cases, given that e-cigarette vapor doesn’t contain carbon monoxide, or many other harmful constituents of smoke. The fact that vapers who also continued to smoke showed similar improvements in their condition is likely because they reduced their smoking substantially, by over 75% of their baseline level. To be clear, it is the reduction in smoking that causes the improvements, rather than an effect of vaping itself.


The researchers conclude:


“[Vaping] may be exploited as a less harmful strategy to potentially halt or reverse COPD-related outcomes and, in general, to reduce the risk of smoking-related diseases or the harm from smoking-associated comorbidities. While the sample size in our study was relatively small, the results of this study may provide preliminary evidence that long-term use of [e-cigarettes] is unlikely to result in substantial health concerns in COPD patients.”


Overall, the study is really positive news for the potential of vaping for COPD patients who still smoke. While complete abstinence might be preferable, this isn’t always possible. In these cases, vaping might be able to make a substantial difference where nothing else could.

What is Naturally Extracted Tobacco E-Liquid?

E-juice, also known as e-liquid or vaping liquid, is the liquid that’s placed in the vaping device and subsequently atomized into vapor. When you go to buy e-juice, you’ll notice it contains a mix of several ingredients. These typically include vegetable glycerin (VG), propylene glycol (PG), some type of flavoring, and nicotine.

VG and PG form the base of the e-liquid. VG is a component used in food and personal care products; its role in e-liquid is to create a thick, dense vapor. PG is another popular solvent used in a variety of everyday items. It carries the e-liquid flavor, provides the “throat hit,” and enhances the vaping liquid’s ability to soak into wicks or cartomizer materials.

Nicotine is an optional ingredient, often available in different levels. E-juice also contains some type of flavoring.

Black Note leads the pack of tobacco vaping liquid by using only natural flavoring – extract from real tobacco leaves to produce real tobacco taste. When you go to buy e-juice from other companies, you may find any number of chemicals used to create synthetic flavors that include fake strawberry, manufactured vanilla, and even man-made tobacco flavors.

If your aim when you buy e-liquid is to experience the subtle nuances, genuine flair and authentic taste of real tobacco, then you’ll be on the mark if you buy e-juice from the Black Note lineup.

Best E-Juice

When you’re going to buy e-liquid, it’s only natural you’ll want the best e-liquid. But what, exactly, does it “best e-juice” mean? We’ll tell you.

For starters, you’ll want an e-juice that doesn’t contain all kinds of strange chemicals and concoctions that you can’t even pronounce. True, even the best e-liquid will contain vegetable glycerin (VG) and proplene glycol (PG), which serve as the base of e-juice, but you don’t necessarily need a host of other chemical compounds.

The best e-juice will stick to natural ingredients, like real tobacco extract, rather than rely on synthetic flavorings, colorings and other additives. Diacetyl is one of those synthetic ingredients that has gotten a pretty bad rap, although its use is not all that uncommon for producing sweet e juice flavors.

Definitely read the ingredient list before you buy e-juice to ensure you recognize what’s on it. Better yet, see if the e-juice company offers a lab report to confirm what’s actually inside the e-liquid.

In addition to having as few chemical ingredients as possible, the best e-juice will have an amazing taste. For those who enjoy authenticity over imitation, the most amazing taste is the most natural taste, especially when it comes to tobacco. Since Black Note uses real extract from tobacco leaves, we not only avoid all those weird chemical flavorings, but we also produce the most authentic experience: tobacco vaping liquid that actually tastes like tobacco.

Vape Juice Ingredients

Vape juice ingredients can be pretty straightforward – or not. At the very least, most vape juice contains propylene glycol (PG), vegetable glycerin (VG), and some type of flavoring. Nicotine has largely become an optional ingredient that can be included at varying levels or left out altogether.

Vegetable glycerin (VG) and propylene glycol (PG) are usually the two main ingredients that make up the base of most vape juice.

VG is a plant-based substance with the ability to produce a dense, thick vapor. PG is an additive found in many food items and certain medicines. It carries the flavoring, provides the “throat hit” and enhances the vape juice’s ability to soak into the wicking materials.

Nicotine levels can vary, as can ingredients that make up the flavorings. The components that make up vape juice flavoring are where ingredients can get rather complicated.

Vape juice that relies on artificial flavorings can contain any number of extraneous chemicals and other additives, whatever it takes to recreate the flavor the ecig juice is going for.

Black Note uses only natural flavorings: extract from real tobacco leaves. That keeps our ingredient list incredibly simple, backed by a lab report to prove it. You won’t find any strange chemical concoctions used to produce our tobacco flavor, just real tobacco extract that delivers a real tobacco experience.

What is the Best Flavor for Ecig Juice?

From strawberry shortcake to banana rum, ecig juice comes in tons of flavors. While folks can debate and discuss all the fruity, sweet or food-like flavors all day long, the best flavor for e-cig liquid is straight-up tobacco.

Why? Vaping was originally created as an alternative for traditional cigarettes, mainly for those who enjoy the taste of tobacco. And when you can find an e-cig liquid that is able to recreate tobacco’s full-bodied yet delicate flavor notes and nuances, but without the harmful chemicals found in cigarettes, then you’ve found the best ecig juice.

Recreating tobacco’s complex flavor isn’t easy, especially when it’s attempted with artificial ingredients. That’s why Black Note sticks to the real thing, extracting the essence of real tobacco leaves to flavor our vaping liquid. Not only does this avoid the harmful chemicals in cigarettes, but it also eliminates the flavoring chemicals found in many ecig juices. The end result is real tobacco taste, an authentic tobacco experience and the best flavor for ecig juice you can find.

Notice also we said the best e-cig flavor was straight-up tobacco, not plain old tobacco. Black Note’s real tobacco vaping liquid happens to come in a variety of different blends, from the light and airy to the peppery and robust. Not all tobacco is created equal, and different blends capture the specialized subtleties that make each tobacco unique.

Best Sweet Tobacco E-Juice

When it comes to sweet tobacco e-juice, your options can be broken down into two categories.

The first category contains tobacco e-juice that overlays the tobacco flavor with artificial chocolate, caramel, vanilla, fruity or other dessert-like flavorings. We wouldn’t classify any such flavors as the best tobacco e liquid, simply because they typically use chemicals and other artificial ingredients to create the tobacco taste, the sweet taste, or both.

The second category of sweet tobacco e-juice is where you’ll find the best tobacco e-liquid, sweet or otherwise. This category contains vaping liquid created using only natural flavorings, which is exactly where Black Note fits in. Instead of concocting flavors using synthetic ingredients, Black Note uses an extensive extraction process that slowly and deliberately extracts the tobacco essence from real tobacco leaves.

The result is the best tobacco e-juice: tobacco vaping liquid that actually tastes like real tobacco. And if you’re going for the best sweet tobacco e liquid, we have a few tobacco blends that offer varying levels of sweetness.

Prelude is our sweetest tobacco e-liquid, containing golden Virginia tobacco. Made from fire-cured dark Virginia tobacco, Sonata is our Cavendish blend with a mildly sweet and nutty flavor. Solo is our menthol blend, giving you a semi-sweet minty taste created from natural menthol crystals extract from dried mint leaves.

For the best tobacco e-liquid that’s naturally sweet and remarkably delicious, Black Note is at your service.
