Conclusion: Inhaled e-cigarette vapor augments PPE model AAA, accompanied by enhanced regulation of genes known to be involved in AAA development. While adding nicotine leads to more pronounced effects, e-juice vapor alone can lead to enhanced aneurysmal growth compared to room air. Footnotes
Can smoking cause brain aneurysms?
Vital Information: Researchers say smoking may cause the brain's blood vessels to develop multiple aneurysms, or weak spots. Doctors note that half the patients who suffer a ruptured aneurysm in their brain will die. Observers say they are not certain whether some people are born more vulnerable to brain aneurysms than others.
What are the health risks of vaping?
Mint vapes, for example, leave people more sensitive to the effects of bacterial pneumonia than mango flavoring. Researchers at University of California San Diego School of Medicine report that daily use of pod-based e-cigarettes alters the inflammatory state across multiple organ systems including the brain, heart, lungs and colon.
Can a brain aneurysm rupture from marijuana use?
An aneurysm is a dilation of a blood vessel (similar to a balloon) which as it expands has the potential for rupture. So when blood rushes suddenly to the head of a person with brain aneurysm, that blood vessel can rupture. I believe marijuana raises blood pressure significantly.
Why is vaping nicotine so addictive?
Vaping nicotine is addictive because of the way it works in your brain. Nicotine enters the brain quickly to activate reward pathways and cause the release of endorphins, your body’s natural pain-killers. Vaping is a particularly powerful way of exposing your brain to nicotine because the juices used have such a concentrated amount of nicotine.
What is a vape pen?
With vaping, a device (typically a vape pen or a mod — an enhanced vape pen — that may look like a flash drive) heats up a liquid ( called vape juice or e -liquid) until it turns into a vapor that you inhale. “Vaping is a delivery system similar to a nebulizer, which people with asthma or other lung conditions may be familiar with,” says Broderick. ...
What is the chemical that can damage your lungs?
Acrolein: Most often used as a weed killer, this chemical can also damage lungs.
Is second hand vapor safe?
Secondhand Vapor Isn’t Safe Either. It’s a myth that secondhand emissions from e-cigarettes are harmless. Many people think the secondhand vapor is just water, but this couldn’t be farther from the truth. The vapor emitted when someone exhales contains a variety of dangerous substances, which may include: Nicotine.
Does vaping affect the lungs?
Instead of bathing lung tissue with a therapeutic mist, just as a nebulizer does, vaping coats lungs with potentially harmful chemicals. E-liquid concoctions usually include some mix of flavorings, aromatic additives and nicotine or THC (the chemical in marijuana that causes psychological effects), dissolved in an oily liquid base.
Why are some people born with brain aneurysms more vulnerable than others?
If so, environmental factors like smoking and high blood pressure may trigger the problem .
What percentage of people with aneurysms have hypertension?
Of those with ruptured aneurysms, 58% had hypertension, and 71% smoked. Smoking was also linked as a possible cause of multiple aneurysms in patients. Of the 67 people who had several aneurysms, 75% had a history of smoking, says Krishnamurthy, a neurosurgical resident with the Milton S. Hershey Medical Center and Penn State College of Medicine.
Can smoking cause a stroke?
Vital Information: Researchers say smoking may cause the brain 's blood vessels to develop multiple aneurysms, or weak spots. These weak spots can rupture and cause bleeding that can lead to stroke, disability, and death. Doctors note that half the patients who suffer a ruptured aneurysm in their brain will die.
How common is an unruptured aneurysm?
Unruptured intracranial aneurysms are common, and 1% to 5% of the population may harbor an unruptured intracranial aneurysm. 1 Despite advances in management, subarachnoid hemorrhage from aneurysmal rupture still has high morbidity and mortality. 1 Tobacco contains >7000 different chemicals, including nicotine, and tobacco product use is associated with various cardiovascular and cerebrovascular diseases. 2 Tobacco cigarette smoking is an independent risk factor for intracranial aneurysmal rupture, and the rupture risk in current smokers is 3× higher than that of nonsmokers. 3
Is smoking a risk factor for an aneurysm?
Tobacco cigarette smoking is considered to be a strong risk factor for intracranial aneurysmal rupture. Nicotine is a major biologically active constituent of tobacco products. Nicotine’s interactions with vascular cell nicotinic acetylcholine receptors containing α7 subunits (α7*-nAChR) are thought to promote local inflammation and sustained angiogenesis. In this study, using a mouse intracranial aneurysm model, we assessed potential contributions of nicotine exposure and activation of α7*-nAChR to the development of aneurysmal rupture.
Does smoking cause aneurysm rupture?
Epidemiological studies have repeatedly shown a positive association between tobacco cigarette smoking and aneurysmal rupture (ie, aneurysmal subarachnoid hemorrhage). However, underlying mechanisms are not well understood nor is the specific role played by nicotine itself as opposed to other constituents of tobacco and of cigarette smoke. Our data indicate that nicotine exposure alone increases rates of aneurysm rupture in a mouse model and that this occurs through activation of VSMC α7*-nAChR. These observations are supported by studies showing that α7*-nAChR–selective antagonism or global knockout of nAChR α7 subunits abolishes the deleterious effect of nicotine exposure on aneurysmal rupture. Moreover, α7 KO specific to VSMCs, but not in inflammatory cells such as macrophages and granulocytes, abolished nicotine’s promotion of aneurysmal rupture.
Does nicotine increase aneurysm rupture rate?
Because nicotine increased the rate of aneurysmal rupture, we then investigated whether activation of α7*-nAChR mediates nicotine’s effects using an α7*-nAChR–selective agonist, AR-R17779. There was no significant difference in the incidence of aneurysm formations between vehicle or α7*-nAChR agonist treatment groups (62% versus 72%; n=16 versus n=18; Figure 2A ). However, the α7*-nAChR agonist significantly increased aneurysmal rupture ( Figure 2A; 40% versus 92%; P <0.05). Mice treated with the α7*-nAChR agonist had significantly worse symptom-free survival compared with vehicle (Kaplan-Meier log-rank P <0.05; Figure 2A ). There was no significant difference in blood pressure, aneurysm location, or aneurysm size between 2 groups (Tables I and II in the online-only Data Supplement ).
Does nicotine affect TGF?
Interestingly, nicotine reduced mRNA levels of TGF-β in our model, but an α7*-nAChR antagonist did prevent this effect of nicotine. Other nAChR subtypes, such as α9*- or α4β2-nAChR, may regulate TGF-β signaling instead. 33 As TGF-β can protect against pathological vascular remodeling, 34, 35 α7*-nAChR–independent downregulation of TGF-β by nicotine may further destabilize vascular wall and promote rupture of intracranial aneurysms.
Why is vaping so difficult?
This is due to the difficulty in correctly identifying what they inhaled, especially when they are intubated or unconscious.

How long does a vape last?
Did you know most cigarettes are smoked within two to five minutes? E-cigarettes on the other hand can last up to 20 minutes, delivering more nicotine and damaging chemicals to the lungs. In addition, some vaping mixtures can contain 20 times the nicotine that a single cigarette contains.
What is an e-cigarette?
E-cigarettes are battery-operated devices that heat a liquid solution — usually, but not always, containing nicotine — turning it into a vapor that can be inhaled . If the base nicotine mixture is not palatable, many flavors, such as mint, apple and others, can make vaping attractive, especially to adolescents.
