These adults underwent only one session with their nicotine-free e-cigarettes, but it was a heavy one: Each person took 16 pulls lasting three seconds each. Doing so had three major effects on the artery and the blood that flowed through it.
Where Do These Effects Come From?
Because nicotine wasn’t a factor in this study, this study puts the focus on how traditional e-liquid components interact with the body. Two of these major ingredients in e-liquids are propylene glycol and glycerol. The e-liquid used in this study contained both.
Does vaping affect femoral artery?
Doing so had three major effects on the artery and the blood that flowed through it. That heavy vaping session changed reduced the dilation of femoral artery by 34 percent on average — which means that it didn’t relax in response to an increase in blood flow as much as it did before the vaping session.
Does vaping increase pulse velocity?
The real metric that bolsters their argument was a change in aortic “pulse wave velocity,” which is essentially a way to measure how stiff an artery is. It’s also used to predict heart disease risk. After a session of vaping, pulse wave velocity increased by three percent, which “suggests acute arterial stiffening.” That’s not a great sign, though Wehrli adds that we still don’t know whether this would translate to prolonged stiffening with repeated use.
Does vaping reduce hemoglobin?
Finally, they found that vaping decreased hemoglobin saturation by 20 percent. Hemoglobin is the protein in red blood cells that carries oxygen, so this suggests that the blood was less oxygen-rich after a vaping session.

Why are neutrophils fewer?
Significantly fewer neutrophil cells migrated in response to signals from bacteria after being exposed to e-cigarette vapor. Exposure to e-cigarette vapor also impeded the neutrophils’ ability to produce bacteria-fighting compounds.
How do neutrophils fight infection?
They play a key role in fighting infection. Neutrophils are attracted to chemicals given off by bacteria cells, allowing them to migrate to the sight of an infection. Once there, they create various compounds to wipe out bacteria cells. Past research has shown that exposure to environmental toxins such as cigarette smoke can make neutrophils less effective.
Why are neutrophils attracted to bacteria?

How does smoking affect the hematopoietic system?
Indeed, smoking is associated with an increased risk of chronic obstructive pulmonary disease (COPD) and lung cancer but also with extrapulmonary diseases such as cardiovascular disease, diabetes mellitus, and bladder cancer. 2–6 In this context, observational studies have associated smoking with end products of hematopoiesis 7–18 and hematologic neoplasms. 19–22 Although all studies have observed a positive association between smoking and total white blood cell counts, there have been some conflicting results for the subpopulations. 9, 10, 13 Conflicting results have also been observed in the association between smoking and thrombocytes and some red blood cell indices. 8, 10, 13, 16, 17 Since observational studies are usually prone to confounding and reverse causation, it is still uncertain whether tobacco smoking causally influences the hematopoietic system. This is an important question, as smoking is a potential reversible risk factor, and if smoking is causally associated with the hematopoietic system, it can ultimately change the understanding of many hematologic diseases. 23
Does smoking affect thrombocytes?
Whether tobacco smoking causally affects white and red blood cells and thrombocyte counts is unknown. Using a Mendelian randomization approach, we tested the hypothesis that smoking causes increases in these blood cell indices.
Does smoking increase hematocrit?
Smoking causes increased blood leukocytes, neutrophils, lymphocytes, and monocytes, as well as increased hematocrit, hemoglobin, and mean corpuscular volume. In contrast, tobacco consumption was not causally associated with eosinophils, basophils, or erythrocytes.
What are the cells that make up the immune system?
White blood cells ( WBCs) are a heterogeneous group of nucleated cells that function mainly as immune cells. WBCs originate in the bone marrow, and can be classified into granulocytes (neutrophils, eosinophils and basophils), and agranulocytes (lymphocytes and monocytes). Cigarette smoking generates several chemicals that are implicated in oxidative stress pathways and systemic inflammation (Lee et al., 2012 ). Elevated WBC count in tobacco cigarette smokers have been well documented (Higuchi et al., 2016; Jensen et al., 1998 ), whereas tobacco abstinence is associated with sustained decrease in WBC count (Abel et al., 2005 ). While the prevalence of tobacco smoking is decreasing (Wang et al., 2018 ), the use of other combustible products such as cannabis is increasing in the United States (Grucza et al., 2016 ).
Is there research on cannabis and the immune system?
Research on cannabis use and the immune system in the general population is scarce (Friedman et al., 1990; Rajavashisth et al., 2012 ). The 2018 report of the National Academies of Sciences, Engineering and Medicine identified the lack of studies on cannabis use and immunity in healthy individuals as a research gap (National Academies of Sciences, 2017 ).
Does cannabis lower immune system?
Conversely, studies in adolescence and young adults indicated that cannabis use is not associated lowered immune responses (Ferguson et al., 2019; Costello et al., 2013 ). The reported anti-inflammatory effects of cannabis were greatly attenuated when body weight is controlled for. This suggests that the inverse cannabis-body weight association might explain the lower levels of circulating inflammatory biomarkers in adult cannabis users (Penner et al., 2013; Le Strat and Le Foll, 2011; Alshaarawy and Anthony, 2019 ), given the strong association of inflammation and adiposity (Esser et al., 2014 ). The results of the current study indicate elevated WBC count among heavy cannabis users, and persisted after adjusting for BMI. This increase might be related to the inflammatory effects of combustion by-products as the most common mode of cannabis use is smoking (Grotenhermen, 2003 ). The association of cannabis and WBCs was evident in heavy users only, which might indicate increased exposure to proinflammatory chemicals generated from smoking (Wei et al., 2016 ).
Does cannabis affect neutrophils?
Positive associations between heavy cannabis use, and total WBC and neutrophil counts were detected. Clinicians should consider heavy cannabis use in patients presenting with elevated WBC count. Research on heavy cannabis use and cardiovascular health is needed as systemic inflammation, increased cardiovascular risk and increased mortality risk have been all associated with WBC elevation within the normal physiologic range (Lee et al., 2001 ). Additionally, studies with repeated measures are needed to study immunomodulatory changes in cannabis users, and whether the mode of cannabis use can differentially affect immune responses.
Does cannabis increase WBC?
These alterations of immune responses by cannabis use might be associated with increased susceptibility to infections and hence the higher WBC count. Indeed, Tsai et al. have reported an association between regular cannabis use and suboptimal self-rated health status, independent of tobacco smoking (Tsai et al., 2017 ). Yet, it is possible that the elevated WBC and suboptimal health status contributed to cannabis use rather than cannabis use caused suboptimal health. This hypothesis, though, cannot be tested as NHANES does not collect information on cannabis use motives. Another potential mechanism can be through the effect of cannabinoids on stem cells. Pre-clinical studies suggest that cannabinoids stimulate hematopoiesis (Valk et al., 1997 ), and hence this stimulation to bone marrow tissues can be associated with increased circulating WBC count in cannabis users.
How do e-cigarettes affect neutrophils?
A new study published in the Journal Cell Physiology shows that e-cigarettes have toxic effects on neutrophils function, making them a threat to human health by increasing the likelihood of infection with Gram-negative bacteria. E-cigarettes are in wide use today, among 7% to 12% of adults and up to 37% of teenagers/new adults.
What is the purpose of vaping liquids?

Neutrophils in culture. The researchers found a 4-fold reduction in chemotaxis in human neutrophils exposed to e-cigarette vapor. Normally, their attraction to Gram-negative bacteria occurs in response to the cell wall component f-Met-Leu-Phe.
What is the role of e-cigarette smoke in the neutrophil attack?
They were also partially disarmed by e-cigarette smoke, which reduced reactive oxygen species (ROS) production within the immune cells by 48%. ROS are at the heart of neutrophil attack by what biologists call the neutrophil extracellular trap (NET). These fascinating antibacterial weapons are structures created from DNA strands coated with sticky proteins or peptides that fight microbes.
Is vaping safe?

E-cigarettes have become a topic of hot controversy, with some people arguing their safety vis-à-vis conventional cigarettes, and others pointing out the almost complete lack of knowledge regarding the safety of inhaled chemicals in e-cigarette smoke, and their physiological effects.
Can e-cigarettes affect endothelial cells?
Their RNA sequencing studies on lung tissue from these animals also show that endothelial cells may be impacted by the e-cigarette vapor, such that they have a lower production of proteins that stimulate the passage of leukocytes out of the blood vessel into the infected site.
Is it safe to smoke e-cigarettes?
E-cigarettes are in wide use today, among 7% to 12% of adults and up to 37% of teenagers/new adults. While touted as a safer alternative to conventional smoking, evidence shows that they can be extremely harmful and in fact, lethal, as the recent spate of vaping-linked deaths in America shows.
