The base case assumes that vaping annually increases smoking initiation by 2% and smoking cessation by 10%. Sensitivity analyses raise the initiation rate increase to 6% while decreasing the cessation rate increase to 5%. Sensitivity analyses also test vaping’s reducing the health benefits of quitting smoking by 10%. Results

Blaha says there's evidence that young people who vape are more likely to go on to use illicit drugs and tobacco products such as cigarettes.
Does smoking increase nicotine receptors?
Over time, as you continue to smoke, the number of nicotine receptors in your brain increases. Addicted smokers have billions more of these receptors than nonsmokers do.
How long does it take to develop a nicotine addiction from vaping?
"Nicotine Addiction Can Start Within A Few Days And After Just A Few Cigarettes." ScienceDaily. ScienceDaily, 13 September 2000.
Does vaping affect dopamine receptors?
Vaping is a Terrible Start Nicotine also mimics dopamine, often called the “pleasure chemical.” Just as it does with acetylcholine receptors, the brain responds to overstimulation of dopamine receptors by eliminating some receptors and diminishing the effects of pleasurable activities.
What does vaping nicotine do to your brain?
Brain Risks These risks include nicotine addiction, mood disorders, and permanent lowering of impulse control. Nicotine also changes the way synapses are formed, which can harm the parts of the brain that control attention and learning.
How does nicotine affect nicotinic receptors?
Nicotine, like ACh, is a nicotinic receptor agonist. The binding of nicotine and ACh to nicotinic receptors cause a conformational change that either opens or closes the receptors' ion channels, thereby changing the receptors' functional state.
What are the benefits of vape?
Benefits of vaping Vaping can help some people quit smoking. Vaping is usually cheaper than smoking. Vaping is not harmless, but it is much less harmful than smoking. Vaping is less harmful to those around you than smoking, as there's no current evidence that second-hand vapour is dangerous to others.
Can one puff of a vape get you addicted?
696). In sum, according to the "hooked on nicotine" line of research, adolescents can lose autonomy over their smoking after having smoked one puff in their lifetime and never having smoked again and can become mentally and physically addicted to nicotine even if they have never smoked a puff.
Is vaping worse than smoking?
Smoking has been proven to cause cancer, which can kill you. But vaping has been proven to cause serious lung illness, which can also kill you. The bottom line is: Smoking kills. Vaping kills you faster.

Does nicotine improve memory?
Preclinical models and human studies have demonstrated that nicotine has cognitive-enhancing effects, including improvement of fine motor functions, attention, working memory, and episodic memory.
Does nicotine help ADHD?
Nicotine may increase attention and reduce hyperactivity and impulsivity and, thus, may regulate behavior in individuals with ADHD. Alleviating the symptoms of ADHD and increasing cardiovascular activity through smoking may mimic the effects of stimulant medications and can be a form of self-medication.
Do cigarettes increase dopamine?
Stimulation of central nAChRs by nicotine results in the release of a variety of neurotransmitters in the brain, most importantly dopamine. Nicotine causes the release of dopamine in the mesolimbic area, the corpus striatum, and the frontal cortex.
How long does it take for your nicotine receptors to return to normal?
Nicotine is out of your body 72 hours after you quit smoking. Nicotine withdrawal symptoms usually reach their peak 2 to 3 days after you quit, and are gone within 1 to 3 months. (1) It takes at least 3 months for your brain chemistry to return to normal after you quit smoking.
Does smoking lower dopamine?
One study showed smokers had lower dopamine release compared to healthy control (Busto et al. 2009), while the other study reported a trend level reduction in dopamine release in smokers (Wiers et al.
What do nicotine receptors do?
A key function of nicotinic receptors is to trigger rapid neural and neuromuscular transmission. Nicotinic receptors are found in: The somatic nervous system (neuromuscular junctions in skeletal muscles). The sympathetic and parasympathetic nervous system (autonomic ganglia).

What is the US nicotine vaping product simulation model?
US Nicotine Vaping Product SimSmokeSimulation Model: The Effect of Vaping and Tobacco Control Policies on Smoking Prevalence and Smoking-Attributable Deaths
How has smoking decreased in the US?
Since the Surgeon General’s Report in 1964, smoking prevalence has declined by more than 50% in the US [1,2]. Simulation models show that much of this reduction can be explained by smoking tobacco control policies [1,2,3,4,5], especially increased cigarette taxes, smoke-free air policies, media campaigns, restrictions on youth access to tobacco, and cessation treatment policies [1,6]. While simulation models project that US smoking prevalence will continue to decline under current policies [3,7,8,9,10,11], they also indicate that prevalence will not drop below 10% for at least another two decades. That trajectory may change now that NVPs are more widely used. As a country with relatively unrestrictive policies [12,13], the US provides a case study of the potential impact of NVPs on smoking.
What is NVP in smoking?
NVPs represent a new generation of nicotine delivery products, which have become progressively more efficient in delivering nicotine to the user [14,15,16 ]. Studies indicate that NVP use has enabled smokers to quit smoking [17,18,19,20,21] and has replaced cigarette smoking among some youth and young adults [22,23,24]. Other studies suggest that NVP use may lead to youth cigarette smoking [25,26], inhibit smoking cessation [27,28] and promote relapse [29,30]. Predicting the impact of NVPs on smoking prevalence depends on the ability to accurately incorporate transitions between NVP use and smoking [31]. However, that data are often limited and, as a disruptive technology [32,33], NVP use and associated transitions may be unstable.
How does NVP affect public health?
NVP use would improve public health to the extent that they replace smoking by those who would have otherwise initiated cigarette use or who would not have otherwise quit smoking, and negatively impact public health to the extent that it acts as a gateway to smoking or is used as a substitute for smoking cessation.
How is the effect of taxes incorporated?
The effect of taxes is directly incorporated through the average price after tax. The price elasticity is used to convert the price changes (%) into effect sizes
When was the NVP model validated?
We first validate the model over the time period 1993–2012, before NVP use became more widespread. That model is then used to extrapolate trends in smoking prevalence in the absence of NVPs in the post-NVP period of 2012–2018, which is then compared to actual smoking prevalence.
How does vaping affect smoking?
For our base-case simulation, we assume that vaping by previously never-smoking adolescents increases the overall smoking initiation rate by 2%. This increase is applied every year to the status quo rate of initiation described above (ie, the smoking initiation rate in the complete absence of e-cigarettes). Soneji et al. 10 concluded that vaping by previously never-smoking young people increased their odds of trying cigarettes by 3.50. Employing this odds ratio and data from Monitoring the Future (MTF) and the Population Assessment of Tobacco and Health (PATH) survey, we estimate that e-cigarettes increased any subsequent cigarette use (by all members of the age group) by 3.35%. Most youthful cigarette users do not become regular smokers. Although no study gives a precise estimate of transitions to regular smoking, recent papers provide guidance. 56–59 See the supplementary material for the specific calculations producing the 2% increase in the initiation rate.
How much does vaping reduce mortality?
Third, sensitivity analyses #1 and 3 assume that all people who successfully quit smoking with vaping lose 10% of the mortality reduction experienced by smokers who quit without vaping. This is equivalent to assuming that half of vaping-induced quitters will continue to vape for their remaining lives, losing 20% of that mortality reduction, whereas the remaining half will quit soon enough after stopping smoking to avoid any serious vaping-related health consequences. In the United Kingdom, already a third of former smokers who used vaping to quit have stopped vaping as well. 13
What is the sensitivity analysis of vaping?
Sensitivity analysis 1 employs the base case initiation and cessation rate assumptions but assumes that every smoker who quits smoking as a result of vaping loses 10% of the mortality reduction associated with quitting smoking outright. This is the equivalent of assuming that life-long vapers lose 20% of the mortality reduction, with half of all vaping-induced quitters continuing to vape until they die.
How many life years are lost from vaping?
In all years, the hypothesized vaping-induced increase in cessation produces many more life-years gained than are lost due to the assumed vaping-induced initiation. No life-years are lost due to vaping-induced initiation in 2020 and 2030 because we assume that no smoking-related deaths occur before age 35.
How long does it take to determine the effects of vaping?
Although research on e-cigarette issues has proliferated, 22, 26, 27 determination of vaping’s ultimate impacts will take decades, if indeed those impacts will ever be clearly discerned from the multiplicity of patterns of conventional and novel nicotine and tobacco product use. Focusing on specific issues, while controlling for the vagaries of “the real world,” simulation models offer potential to develop near-term insights regarding important likely effects, while helping to identify the most important questions warranting further study.
Does smoking cessation affect life?
In the most conservative sensitivity analysis (#3), life-years saved by additional vaping-induced smoking cessation exceed life-years lost by vaping-induced smoking initiation by three-quarters. In the base case simulation, utilizing what we consider the most plausible assumptions, life-year gains exceed losses by a factor of 13.7.
Is e-cigarettes good for health?
Our analysis strongly suggests that the upside health benefit associated with e-cigarettes, in terms of their potential to increase adult smoking cessation, exceeds their downside risk to health as a result of their possibly increasing the number of youthful smoking initiators. Public messaging and policy should continue to strive to reduce young people’s exposure to all nicotine and tobacco products. But, they should not do so at the expense of limiting such products’ potential to help adult smokers to quit.
How much did nicotine increase in 12th grade?
The overall use of nicotine with any product increased significantly, by 5.2 percentage points from 23.7% to 28.9%, in the sample of 12th-graders who answered questions on both vaping and use of tobacco products. This increase was driven solely by nicotine vaping, given that the use of each of the other six nicotine products declined (although not significantly).
How many teens vape in 2018?
The 1-year increases in the prevalence of nicotine vaping translate into approximately 1.3 million additional adolescents who vaped in 2018, as compared with 2017. This estimate was calculated on the basis of approximately 16 million youths 3 in grades 9 through 12, with interpolation of the increases in grades 9 and 11 as the mean of the increases in the adjacent grades. Put in historical context, the absolute increases in the prevalence of nicotine vaping among 12th-graders and 10th-graders are the largest ever recorded by Monitoring the Future in the 44 years that it has continuously tracked dozens of substances.
How many percentage points do 10th graders vape?
There was a sharp increase in the prevalence of nicotine vaping — 10.0 percentage points among 12th-graders, 7.9 percentage points among 10th-graders, and 2.6 percentage points among 8th-graders ( Table 1 ). The increases were similar in the combination measure of adolescents who reported vaping nicotine or “just flavoring” (or both) — a measure that captures data regarding youths who may unknowingly vape nicotine.
Is vaping a problem for adolescents?
A rapid increase in the prevalence of vaping among adolescents has aroused public health concern. Adolescents who “vape” use a device such as an electronic cigarette to inhale a heated aerosol, which typically contains nicotine. In 2017, vaping was the most common use of any tobacco-like product among adolescents. 1 This is a rapid rise from a near-zero prevalence of vaping in 2011. 2 We assessed whether the prevalence of nicotine vaping increased among adolescents from 2017 to 2018.
Why is tobacco used in adolescence?
Because of nicotine dependence and social factors, initiation of tobacco products during adolescence is closely associated with persistent smoking in adulthood and with the many adverse health effects associated with chronic smoking.
When do you start smoking cigarettes?
