How Many Cigarettes Are in a Vape?
Vaping involves inhaling and exhaling aerosol, commonly known as vapor, generated by an electronic device. This device, an e-cigarette, vape pen, or mod, heats a liquid containing nicotine, flavorings, and additional chemicals, typically stored in a pod or cartridge that attaches to the device. Vaping has become a widely embraced alternative to smoking, particularly among the youth demographic.
As per the World Health Organization, the global number of vapers surged from 7 million in 2011 to 41 million in 2018.
Many individuals turn to vaping under the belief that it is a less harmful alternative to smoking, either as a means to quit smoking or to reduce nicotine consumption. Despite these intentions, vaping is not without its own set of risks, with uncertainties surrounding its long-term health effects. A crucial query among vapers and smokers alike is: how do the nicotine levels in a vape compare to traditional cigarettes? Addressing this question is intricate, given the various factors influencing the delivery of nicotine and other substances to the user.
Drawing a direct comparison between cigarettes and vapes proves challenging due to the multitude of variables affecting substance delivery. This article delves into these complexities, examining the methods and metrics employed in assessing cigarettes versus vapes. Furthermore, it explores findings from diverse studies and sources, shedding light on the elusive question: how many cigarettes are equivalent to vaping?
How to Compare Cigarettes and Vapes?
The comparison between cigarettes and vapes is significantly influenced by the nicotine content, which is the addictive component in tobacco, stimulating the brain and nervous system. Nicotine can impact the body by elevating blood pressure, heart rate, and breathing. Various metrics measure nicotine, including concentration (e.g., mg/mL), mass (e.g., mg or g), dose, and the absorbed amount subject to user behavior and physiology.
Nicotine content in cigarettes and vapes varies, and it is affected by brand, type, and quality. The U.S. FDA notes an average nicotine content of 10 to 14 mg in cigarettes, but only 1 to 2 mg is absorbed. Vape nicotine concentrations range from 0 to 36 mg/mL, with pod or cartridge nicotine masses varying from 6 to 59 mg. Vapers absorb approximately 0.5 to 1 mg per unit.
Puff duration, frequency, and volume also impact the comparison. These factors vary between cigarettes and vapes and influence nicotine delivery, substance exposure, and potential toxin inhalation. Measurement methods include self-reporting, observation, or electronic monitoring, though standardization is lacking.
Device and eliquid characteristics constitute another factor. These include device type, design, size, material, battery, fluid type, flavor, and additives. Variation exists among manufacturers, brands, models, batches, and user customization, affecting performance, safety, and user experience. Measurement methods involve laboratory testing, chemical analysis, or user feedback, but standardization remains challenging.
In summary, comparing cigarettes and vapes is complex due to diverse influencing factors affecting nicotine and substance delivery, as well as user exposure to potential toxins. The absence of standardized measurement methods and metrics poses challenges, leading to the utilization of various approaches like cigarette equivalents, nicotine delivery, and harm reduction for comparison.
How Many Cigarettes Are in a Vape According to Different Methods and Metrics
The cigarette equivalent is among the most common methods and metrics for comparing cigarettes and vapes. It is the number of cigarettes that have the same amount of nicotine as one pod or cartridge of a vape. The cigarette equivalent can help vapers and smokers estimate how much nicotine they are consuming and how vaping compares to smoking in terms of addiction and dependence. However, the cigarette equivalent has some limitations and variability, and there needs to be a consensus on the best way to calculate it.
Calculations Based on Equivalency of Nicotine Mass the Cigarettes and Vapes
One way to calculate the cigarette equivalent is to divide the nicotine mass of the pod or cartridge by the nicotine mass of the cigarette. For example:
According to the Truth Initiative, a Juul pod contains 59 mg of nicotine, while a Marlboro cigarette contains 10.9 mg of nicotine. Therefore, one Juul pod equals about 5.4 Marlboro cigarettes (59 / 10.9 = 5.4).
However, this method does not account for the nicotine delivery and absorption rates, which are different for vaping and smoking. Moreover, this method does not account for the variability of the nicotine content of other brands and types of cigarettes and vapes.
Calculations Based on the Amount of Nicotine Vapers Get Per Session
Another way to calculate the cigarette equivalent is to use the nicotine yield of the product, which is the amount of nicotine delivered to the user per puff or session.
For example, according to a study by Goniewicz et al. (2015), the nicotine yield of a Juul pod was 0.95 mg per 15 puffs, while the nicotine yield of a Marlboro cigarette was 0.81 mg per 15 puffs. Therefore, one Juul pod equals about 17.6 Marlboro cigarettes (0.95 / 0.81 x 15 = 17.6).
However, this method does not account for the puff duration, frequency, and volume, which are different for vaping and smoking. Moreover, this method does not account for the variability of the nicotine yield of other brands and types of cigarettes and vapes.
Calculations Based on the Amount of Nicotine Absorved in Bloodstreem
A third way to calculate the cigarette equivalent is to use the nicotine blood level of the user, which is the amount of nicotine absorbed and retained in the bloodstream per puff or session.
For example, according to a study by Ramôa et al. (2016), the nicotine blood level of a Juul user was 8.7 ng/mL after 30 minutes of use, while the nicotine blood level of a Marlboro smoker was 16.3 ng/mL after smoking one cigarette.
Therefore, one Juul pod equals about 2.1 Marlboro cigarettes (8.7 / 16.3 x 20 = 2.1). However, this method does not account for the different metabolisms and eliminations of nicotine in vaping and smoking. Moreover, it does not account for the variability of the nicotine blood levels of other users and products.
Cigarettes Equivalent Varies Widely
As we can see, the cigarette equivalent can vary widely depending on the method and metric used to calculate it, as well as the brand and type of the product. According to some studies and sources, one vape pod or cartridge can contain as much nicotine as 20 to 40 cigarettes, depending on the brand and type of device.
However, this does not mean that vaping is equivalent to smoking many cigarettes, as the nicotine absorption and retention rates are different for vaping and smoking. Therefore, the cigarette equivalent should be used with caution and awareness, as it may not reflect the actual amount of nicotine and other substances that the user receives or the actual risk and harm that the user faces.
Comparing Cigarettes and Vapes Nicotine Delivery
Another method and metric used to compare cigarettes and vapes is nicotine delivery. The nicotine delivery is the amount and rate of nicotine that is delivered to the user per puff or session. The nicotine delivery can affect the user's experience and satisfaction, as well as the user's addiction and dependence. The nicotine delivery can be measured using different methods, such as yield, blood level, or pharmacokinetic profile. The nicotine pharmacokinetic profile is the pattern of nicotine absorption, distribution, metabolism, and elimination in the body over time.
The nicotine delivery of cigarettes and vapes can vary depending on the product and user characteristics, as well as the environmental and behavioral factors.
For example, according to a study by St.Helen et al. (2016), the nicotine delivery of cigarettes was higher and faster than the nicotine delivery of vapes, as cigarettes produced higher and sharper peaks of nicotine blood levels than vapes.
However, according to another study by Spindle et al. (2019), the nicotine delivery of vapes was comparable to or higher than the nicotine delivery of cigarettes, as vapes produced similar or higher levels of nicotine blood levels than cigarettes.
Nicotine delivery can vary depending on the method and metric used to measure it and the product's and user's characteristics. According to some studies and sources, the nicotine delivery of vapes can be lower, similar to, or higher than that of cigarettes, depending on the brand and type of device and liquid.
However, this does not mean that vaping is less, equal, or more addictive than smoking, as nicotine delivery is only one of the factors that affect addiction and dependence. Therefore, nicotine delivery should be used with caution and awareness, as it may not reflect the experience and satisfaction of the user or the real risk and harm of the user.
Comparing Cigarettes and Vapes Harm Reduction
A third method and metric used to compare cigarettes and vapes is harm reduction. Harm reduction means reducing the potential harm. The user's risks from using the product include exposure to toxins and carcinogens, developing diseases and disorders, and mortality and morbidity rates. Harm reduction can be measured using different methods, such as chemical, biomarker, or epidemiological analysis. Chemical analysis analyzes the substances generated and delivered by the product, such as aerosol or smoke.
Biomarker analysis analyzes biological indicators, such as trine or saliva, that reflect the exposure and effect of the chemicals on the user. Epidemiological analysis analyzes the health outcomes and trends associated with using the product, such as the incidence or prevalence of diseases and disorders. The harm reduction of cigarettes and vapes can vary depending on the product and user characteristics, as well as the environmental and behavioral factors.
For example, according to a study by Goniewicz et al. (2017), the harm reduction of vapes was higher than the harm reduction of cigarettes, as vapes produced lower levels of toxins and carcinogens than cigarettes, and vapers had lower levels of biomarkers of exposure and effect than smokers.
However, according to another study by Soneji et al. (2018), the harm reduction of vapes was lower than the harm reduction of cigarettes, as vapes increased the risk of initiating and maintaining smoking, and vapers had higher rates of mortality and morbidity than smokers.
As we can see, harm reduction can vary depending on the method and metric used to measure it and the product and user characteristics. According to some studies and sources, the harm reduction of electronic cigarettes can be higher, similar, or lower than the harm reduction of cigarettes, depending on the brand and type of device and liquid.
However, this does not mean that vaping is safer, equal to, or more dangerous than smoking, as harm reduction is only one factor affecting the user's health and well-being. Therefore, harm reduction should be used with caution and awareness, as it may not reflect the chemicals' actual exposure to and effect on the user or the user's health outcomes and trends.
