Even worse, continued vaping decreases the brain’s sensitivity to dopamine, leading to a need for more frequent vaping to trigger the pleasant effects. Regular use also alters the brain circuitry that controls learning, stress, and impulse control. These changes can contribute to withdrawal symptoms.
Is vaping better than smoking?
Some smokers use e-cigarettes to try to kick the habit, but new research shows mixing smoking and vaping is no better for your heart health than just smoking. Among 24,000 men and women, smoking cigarettes and e-cigarettes didn't reduce the risk of heart ...
What are the dangers of vaping?
The interchangeable use of smoking and vaping is most common in people under age 35. They face equal risk of heart attack or stroke than if they lit up exclusively. The takeaway is that there is no ‘best’ method of inhaling nicotine.

Vaping generally affects three main systems:
- Mouth and airways: Irritation, cough and increased airway resistance
- Heart and circulation: Chest pain, increased blood pressure and increased heart rate
- Stomach: Vomiting and nausea
What are facts about vaping?
Vaping is addictive. Vapes contain nicotine, an addictive chemical that is extremely hard to quit. Nicotine is the same drug used in cigarettes, cigars, and other tobacco products. Some vape pods have as much nicotine as 20 cigarettes (a pack of cigarettes). Because your brain is still developing until your mid-20s, you’re more likely to ...

The Effects of Nicotine on the Teen Brain – Mendez Foundation
The Centers for Disease Control and Prevention recently released a study that showed adolescent e-cigarette use tripled between 2013 and 2014. This new trend means we need to look not just at the negative health effects of smoking but at the overall negative health effects of nicotine on the developing teenage brain.
How to teach students about vaping?
As students revise their models, their models serve as formative assessments of their thinking. Teachers should look for the science content to be incorporated into their vaping explanations. For example, students’ models should include a feedback loop and cellular transport of nicotine. Based on the models, teachers may choose to include more experiences or investigations to scaffold the science content.
How common is vaping in high school?
Vaping (the use of an e-cigarette) is a common practice among teenagers; 26.7% of high school students report vaping in the last 30 days ( Johnston, Miech, O’Malley, Bachman, Schulenberg, and Patrick 2019 ), making this issue highly relevant. In order to make an informed decision about the use of e-cigarettes, students need to understand the impacts of vaping on their body, which makes the science content engaging and meaningful. We describe the Vaping Unit by giving an overview of the unit lessons and timeline, a description of key lessons with student examples, and results of a student survey. The entire unit is available at ri2.missouri.edu.
What should teachers look for in vaping?
Teachers should look for the science content to be incorporated into their vaping explanations. For example, students’ models should include a feedback loop and cellular transport of nicotine. Based on the models, teachers may choose to include more experiences or investigations to scaffold the science content.
Is vaping harmful to students?
In the students’ final products, the science is undisputed—vaping is harmful because nicotine disrupts homeostasis, and we do not know enough about other vaping impacts.
Is vaping a problem for teens?
Vaping is a growing epidemic among teenagers, making the issue of e-cigarette regulation extremely relevant to students. In this unit, vaping serves as an anchor phenomenon to teach the science of homeostasis, positive and negative feedback loops, macromolecules, diffusion/osmosis, and macromolecules.
What is the connection between vaping and mental health?
Vaping and mental health: What’s the connection? Vaping devices, also known as e- cigarettes, e-hookahs, mods, vape pens, vapes, tank systems, and electronic nicotine delivery systems, are used to inhale aerosols. Some e-cigarettes look like regular cigarettes, pipes, pens, or USB drives.
How does nicotine affect the health of a smoker?
Like with any addiction, nicotine affects the physical and mental health of smokers. The impact on mental health has been overshadowed by the concerns about physical health. Contrary to popular belief, nicotine content in some vaping devices is much higher than combustible cigarettes.
Why are e-cigarettes harmful?
Some of the flavors used may be harmful when heated and inhaled in form of aerosol. Social or peer pressure has been reported as one of the most common reasons for increased use by adolescents.
What does an e-cigarette look like?
Some e-cigarettes look like regular cigarettes, pipes, pens, or USB drives. It contains a heating element to vaporize a liquid that can include flavor compounds, nicotine, or cannabis-derived compounds such as tetrahydrocannabidiol (THC) and cannabidiol (CBD).
Does Juul pod contain nicotine?
Some nicotine pods like the Juul pod contain as much nicotine as one pack of cigarettes. Researchers have studied several mental health issues associated with vaping in adolescents and young adults. Dependence on nicotine has been associated with impulsivity, mood disorders, anxiety, suicidality and depression.
Is vaping bad for you?
Vaping is often used as a cop ing strategy by individuals suffering from depression, anxiety or other mental health conditions.
Does nicotine cause depression?
Nicotine interrupts the cerebral dopamine pathway leading to an increase in depressive symptoms. Nicotine also increases sensitivity to stress, and alters the coping mechanism in the brain. These changes lead to an increased dose-response relationship – meaning an increase in symptoms with increased exposure to nicotine.
How many times more likely is vaping to cause depression?
The same holds true for former users: People who vaped in the past were 1.6 times more likely to have been diagnosed with depression than those who never pick up an e-cigarette.
How many times more likely are people to have depression than those who don't vape?
Daily users were 2.3 times more likely to have had a depression diagnosis than those who didn’t vape at all. They were also more likely to report poor mental health overall than those who didn’t vape. The same was true for those who vape less frequently.
Why do people smoke cigarettes?
Some studies support a “self-medication model,” which suggests that people start smoking cigarettes to cope with depression or anxiety. Others support an alternative theory — that consistent or prolonged smoking makes people more susceptible to anxiety or depression.
Does vaping cause depression?
These data don’t reveal whether or not that is the case. But the results do indicate that vaping may have a complex relationship with depression reminiscent of the one that’s seen in smokers. More work is needed before we can determine vaping’s affects on our brain, alongside the popular practice’s affects on the rest of our body.
Do vape users have depression?
The results confirm past preliminary evidence. A survey presented in March of this year, for example, suggested that vape users are more likely to report a depression diagnosis than non-users.
Does nicotine affect dopamine?
Previous research suggests that nicotine disrupts dopamine production in the brain, increasing sensitivity to stress and dampening the ability to cope with depression. Other than nicotine, some vape liquids contain heavy metals, which may also play a role, Obisesan says.
Is e-cigarette use related to depression?
Conclusions and Relevance: This study found a significant cross-sectional association between e-cigarette use and depression, which highlights the need for prospective studies analyzing the longitudinal risk of depression with e-cigarette use. If confirmed by other study designs, the potential mental health consequences may have regulatory implications for novel tobacco products.
How long does it take for nicotine to reach the brain?
When a teen inhales vapor laced with nicotine, the drug is quickly absorbed through the blood vessels lining the lungs. It reaches the brain in about 10 seconds. There, nicotine particles fit lock-and-key into a type of acetylcholine receptor located on neurons (nerve cells) throughout the brain.
Why does nicotine bind to acetylcholine?
Once nicotine binds to that receptor, it sends a signal to the brain to release a well-known neurotransmitter— dopamine—which helps create a ‘feel-good’ feeling.
When is nicotine dangerous?
Nicotine can spell trouble at any life stage, but it is particularly dangerous before the brain is fully developed, which happens around age 25.
Is vaping safer than smoking?
Weighing the pros and cons of vaping versus smoking is difficult to do. On the one hand, e-cigarettes likely do not produce 7,000 chemicals—some of which cause cancer—when they are activated, like regular combustible cigarettes do. However, the aerosol from a vape device has not been proven safe. Studies have found that it contains lead and volatile organic compounds, some of which are linked to cancer. Researchers are still gathering data on the possible long-term health effects from vaping. It’s notable that e-cigarettes have not been approved by the Food and Drug Administration (FDA) as smoking cessation devices. However, e-cigarettes may be a better choice for adult smokers if they completely replace smoking, according to the Centers for Disease Control and Prevention (CDC).

What’s more, recent animal study research and human brain imaging studies have shown that “environmental cues, especially those associated with drug use, can change dopamine concentrations in the brain ,” he says.
What is the food additive used to deepen e-cigarette flavors?
Diacetyl: This food additive, used to deepen e-cigarette flavors, is known to damage small passageways in the lungs.
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.
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.
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.
Is it safe to take vitamin E?
And, while it’s safe when taken orally as a supplement or used on the skin, it’s likely an irritant when inhaled. It’s been found in the lungs of people with severe, vaping-related damage.
Does diacetyl help with popcorn lung?
Diacetyl is frequently added to flavored e-liquid to enhance the taste. Inhaling diacetyl causes inflammation and may lead to permanent scarring in the smallest branches of the airways — popcorn lung — which makes breathing difficult. Popcorn lung has no lasting treatment. There are, however, treatments that manage BO symptoms, such as:
What is the psychoactive effect of THC?
Δ9-Tetrahydrocannabinol (THC), cannabis’ main psychoactive component10, elicits its acute psychoactive effects via the endocannabinoid type 1 (CB1) receptor (CB1R)11. THC has been linked to the rewarding aspects of cannabis and the induction of symptoms of mental illnesses and cognitive impairment. Lately the THC content of cannabis has been increasing12, synthetic THC analogues (potent cannabinoid agonists; termed ‘spice’) are now widely used13. The future consumption of cannabinoids through electronic cigarettes (‘cannavaping’) and edible products14changes the landscape further15. Given the widespread use of cannabinoids, and the links between THC exposure and adverse outcomes, it is imperative to understand the neurobiological effects of THC. Recently, we and others have found that heavy cannabis use is associated with reductions in dopaminergic function. Since the rewarding and psychotogenic effects of THC and its analogues are thought to be mediated by the dopaminergic system, demonstrating dopaminergic alterations in vivoin human users is of clinical relevance for the prevention and treatment of cannabis use disorders and psychoses. Therefore, we review the animal and human literature on the complex effects of acute and longer-term THC on dopamine synthesis, release, and its receptors, critically analysing the factors that contribute to effects, and variations between studies, before finally providing a framework for future research including pharmacologically dissecting these effects, especially in the developing brain.
Which striatum is directly associated with decreased motivational levels?
Lower dopamine synthesis capacity in the dorsal striatum is directly associated with reduced motivational levels76and reduced dopamine release in the ventral striatum is directly associated with negative emotion levels and addiction severity70
Which receptors does THC bind to?
THC binds to CB1 receptors on glutamatergic and GABAergic neurons disrupting normal endocannabinoid retrograde signalling from dopaminergic neurons137.
Does THC increase burst firing?
Dose-dependent increases in burst firing in the VTA in response to multiple THC administrations have been reported in nearly all murine electrophysiological studies48, with one exception79. In the substantia nigra pars compacta (SNpc), multiple THC dosing was associated with increased firing, although this was smaller in magnitude than in the VTA80,81. This suggests that VTA and SNpc dopamine neurons develop a differential response to repeated THC exposures. There also appears to be an effect of withdrawal from multiple THC doses whereby decreased firing is elicited by abrupt cessation of repeated THC or administration of the CB1R antagonist SR141716A82.
Does THC increase D2R?
Studies in rats have reported that multiple THC dosing results in increased D2R availability in the midbrain, striatum and PFC65,77and that this is associated with dopamine receptor sensitisation. There is further evidence of downstream dopaminergic effects of THC, as one study in rats78reported up-regulated postsynaptic dopamine receptor signalling in the NAc via increased adenylyl cyclase activity, which was proposed to underlie THC-induced changes in amphetamine-induced locomotive behaviour. These findings suggest that repeated THC dosing results in altered dopamine receptor signal transduction.
Does THC affect dopamine?
From the outset it was clear that THC exerts complex effects on the dopamine system. Early in vitrostudies in rodents using radiolabelled dopamine in synaptosomes found that THC caused increased dopamine synthesis31and release24(Fig. 2). However, the effects on dopamine uptake yielded conflicting results, with evidence of both increases32and dose-dependent decreases24. Subsequently biphasic and triphasic effects of THC were discovered, whereby low doses of THC produced increases in the conversion of tyrosine to dopamine, but high doses of THC resulted in decreased dopamine synthesis33. Likewise, complicated temporal relationships between THC administration and changes in dopamine levels were observed34, such that repeated dosing results in behavioural and neurochemical tolerance –highly pertinent to the mechanisms of dependence to the drug. The complex dose-specific effects of THC in rodents were thought to be due to dose-related decreases in precursor uptake32and dopamine-opioid interactions via μ-opioid receptors31.
Does amphetamine increase dopamine?
Early animal studies described the interactions of amphetamine, which increases dopamine release, and THC23. These reported that amphetamine’s behavioural effects were potentiated or antagonised depending on the dose of THC leading researchers24to propose that dopamine was “a prime candidate for…the mode of action of Δ9-tetrahydrocannabinol”. Indeed, THC produces complex effects on the dopamine system, contributing to the drug’s recreational and harmful effects. However, there are inconsistencies between the preclinical and clinical findings which challenge the field. It is thus timely to review the evidence and provide a framework for understanding the inconsistencies between the preclinical and clinical findings.
How Does Nicotine Affect Dopamine?
Nicotine also has an effect on dopamine, which is also a neurotransmitter. Dopamine is associated with feelings of euphoria and pleasure and is responsible for activating the dopamine reward pathway. The dopamine reward therapy works in that behavior naturally instigates the reward therapy through the feeling of pleasure and reinforces the behavior so that it over and over again. [3] Once nicotine is in your body, it activates receptors in the brain, which in turn causes the release of various neurotransmittersincluding dopamine. The dopamine released makes the smoker feel good and have a feeling of pleasure.
How does dopamine work?
The dopamine reward therapy works in that behavior naturally instigates the reward therapy through the feeling of pleasure and reinforces the behavior so that it over and over again . [3] . Once nicotine is in your body, it activates receptors in the brain, which in turn causes the release of various neurotransmittersincluding dopamine.
Why does nicotine withdrawal occur when you stop smoking?
Even when you try to stop smoking, since the receptors in your brain do not receive nicotine, the pleasure response is cut off thus resulting in nicotine withdrawal symptoms.
What neurotransmitters does nicotine release?
In the brain, nicotine triggers the release of several neurotransmitters including dopamine, serotonin, epinephrine, glutamate, and acetylcholine.
How long does it take for nicotine to get into your system?
On inhaling nicotine, it takes a few seconds for the drug to reach your brain and a few minutes to get into your bloodstream. Some of the immediate effects of nicotine in your body include an increased heart rate and rise in blood pressure. Nicotine has adverse effects on your body, well-being, and also interferes with several transmitters in ...
Does nicotine affect serotonin?
As much as nicotine results in increased levels of serotonin, a continued release of the neurotransmitter results in a decline over time, which impairs the functionality of serotonin in the long run. As a result of decreases serotonin levels, an individual experiences stress, anxiety, poor memory, fatigues, insomnia heart diseases, smoking addiction, and insulin resistance among other complications. Epinephrine is a catecholamine neurotransmitter that is associated with the fight or flight response of the sympathetic nervous system. This neurotransmitter exerts its tissue-specific effect by binding with particular receptors expressed in the target tissue. Nicotine results in an increased level of epinephrine. [2]
Does nicotine interfere with acetylcholine?
It transmits messages related to heart rate, respiration, alertness, memory, and muscle movement. Nicotine interferes with acetylcholine and its receptors because nicotine is shaped similarly to the neurotransmitter and thus can bind with the receptors that acetylcholine binds with.
How does nicotine affect young brains?
Research on young mice and rats shows how nicotine hijacks brain systems involved in learning, memory, impulse control and addiction. The link between vaping and severe lung problems is getting a lot of attention.
What is the role of nicotine in the brain?
Nicotine also acts on the brain's dopamine system, which plays a role in desire, pleasure, reward and impulse control.
Does nicotine fool the brain?
So nicotine is able to fool brain cells that have something called a nicotinic receptor.
Does vaping cause lung problems?
The link between vaping and severe lung problems is getting a lot of attention. But scientists say they're also worried about vaping's effect on teenage brains. "Unfortunately, the brain problems and challenges may be things that we see later on down the road," says Nii Addy, associate professor of psychiatry and cellular ...
Do teens smoke or vape?
For example, studies suggest that physically active teens are less likely than their peers to smoke but no less likely to vape. Another challenge is that it's hard for scientists and regulators to keep up with the rapid pace of change in the vaping world.
Can you use an e-cigarette again?
Research shows that "if the first e-cigarette that you used was flavored, then you're more likely to go on and use an e-cigarette again," Audrain-McGovern says. Another promising approach is to make nicotine-vaping products more expensive.
Does vaping affect your brain?
Animal research by another Yale University scientist suggests that vaping during adolescence can lead to long-term brain changes, like attention deficit hyperactivity disorder, Addy says. "If there's exposure to nicotine early on, that can influence attentional processes later in life," he says.
