How many puffs of cigarettes is an electronic cigarette equivalent to smoking?
Apr 28, 2024
The amount of nicotine contained in an e-cigarette varies depending on the product, as well as the number of puffs smoked. For example, if the nicotine concentration of e-cigarette liquid is 20mg/ml and the user consumes 1ml in one smoking session, their intake of nicotine is equivalent to smoking 10 to 20 traditional cigarettes. However, it should be noted that the actual intake is also influenced by factors such as the power of electronic cigarettes, user habits, and product efficiency.

Comparison of Components between Electronic Cigarettes and Traditional Cigarettes
The main components of electronic cigarettes
Electronic cigarette liquid, commonly referred to as e-liquid or e-liquid, mainly includes the following components:
Nicotine: a chemical substance extracted from tobacco and is the main component in electronic cigarettes. According to the brand and type of e-cigarette, the concentration of nicotine can range from 0mg/ml to 50mg/ml. For example, a certain brand of e-cigarette may provide a nicotine concentration of 20mg/ml.
Propylene glycol: This is another major component in e-cigarette liquid, which helps generate steam and transmit nicotine. Propylene glycol is widely used in food, medicine, and cosmetics and is considered relatively safe.
Glycerol: Like propylene glycol, glycerol is also used to produce steam. Most e-cigarette liquids contain a mixture of propylene glycol and glycerol.
Seasoning agent: used to provide various flavors to electronic cigarette liquids, such as mint, fruit, candy, etc.
The main components of traditional cigarettes
Traditional cigarettes release thousands of chemicals when burned, including:
Nicotine: The main ingredient in traditional cigarettes. On average, a cigarette contains about 1mg to 2mg of nicotine.
Tar: a byproduct of tobacco combustion that is harmful to the human body.
Carbon monoxide: a toxic gas produced during the combustion of tobacco.
Other harmful substances: including benzene, formaldehyde, hydrogen cyanide, etc.
Comparison of harmful substances
Electronic cigarettes differ from traditional cigarettes in terms of the content and types of harmful substances.
Electronic cigarettes: Although electronic cigarettes are considered a healthier alternative to traditional cigarettes, they also contain certain harmful substances such as formaldehyde and acrylic esters. The concentration of these substances is usually lower than traditional cigarettes, but long-term use may still pose a health risk.
Traditional cigarettes: Traditional cigarettes release a large amount of harmful substances when burned. It is estimated that there are over 7000 chemical substances in cigarettes, of which about 70 are related to cancer, such as benzene and formaldehyde.
Nicotine content in electronic cigarettes
How to measure the nicotine content of electronic cigarettes?
When we discuss the nicotine content in e-cigarettes, we are actually discussing the concentration of nicotine in the e-cigarette liquid. This is usually expressed in mg/ml (milligrams per milliliter).
Laboratory measurement method:
This is an accurate method for measuring nicotine concentration in e-cigarettes using high-performance liquid chromatography (HPLC). Firstly, the e-cigarette liquid sample is placed in a chromatographic column and then washed with a specific solvent. By detecting the substances released during the washing process, the laboratory can accurately determine the concentration of nicotine.
Reading packaging labels:
Most e-cigarette liquid packaging will indicate the concentration of nicotine. This is the simplest method, but it depends on the accuracy of the information provided by the manufacturer. For example, if an e-cigarette liquid is labeled as "20mg/ml", it means that each milliliter of liquid contains 20 milligrams of nicotine.
The relationship between nicotine concentration in e-cigarettes and traditional cigarettes
The nicotine supply methods for traditional cigarettes and e-cigarettes are different. Traditional cigarettes release nicotine by burning tobacco, while e-cigarettes release nicotine by heating liquids.
Nicotine content in traditional cigarettes:
Generally speaking, a traditional cigarette contains approximately 1mg to 2mg of nicotine. But this does not mean that smokers will consume all nicotine, as some nicotine will be destroyed during the combustion process.
Nicotine concentration in e-cigarette liquid:
The nicotine concentration of e-cigarette liquid can range from very low (such as 0mg/ml) to very high (such as 50mg/ml or higher). However, e-cigarette users may not smoke e-cigarettes as frequently as traditional cigarettes.
In order to compare the two more intuitively, if the nicotine concentration of an e-cigarette liquid is 20mg/ml and a user consumes 1ml of the liquid in one smoking session, the amount of nicotine they consume is equivalent to smoking 10 to 20 traditional cigarettes.
Comparison of Health Risks between Smoking Electronic Cigarettes and Smoking Cigarettes
The impact of respiratory system
Electronic cigarettes:
The vapor of electronic cigarettes contains some chemicals that can cause respiratory irritation. Long term use of electronic cigarettes may lead to some respiratory problems, such as coughing, shortness of breath, and chest tightness. In addition, some studies have shown that fine particles in e-cigarette vapors may penetrate deep into the lungs, leading to inflammation.
Traditional cigarettes:
Traditional cigarettes release thousands of chemicals when burned, many of which are harmful to the lungs. Long term smoking of cigarettes can lead to chronic bronchitis, emphysema, and other chronic obstructive pulmonary diseases.
The impact of cardiovascular system
Electronic cigarettes:
Although e-cigarettes are considered safer than traditional cigarettes, they also contain nicotine, a substance that can cause accelerated heartbeat and increased blood pressure. These effects may increase the risk of cardiovascular disease, especially in e-cigarettes with high nicotine concentrations.
Traditional cigarettes:
Traditional cigarettes not only contain nicotine, but also other harmful chemicals to the cardiovascular system. Smoking cigarettes can cause arteriosclerosis, coronary artery disease, and stroke. In fact, cigarettes are one of the main controllable risk factors for cardiovascular disease.
Comparison of Cancer Risk
Electronic cigarettes:
Although e-cigarettes are relatively new and research is still ongoing, current evidence suggests that the cancer risk of e-cigarettes is much lower than that of traditional cigarettes. However, electronic cigarette vapors do contain certain known carcinogens, such as formaldehyde and acrylic esters.
Traditional cigarettes:
The smoke produced by cigarette combustion contains various known carcinogens, such as benzene, formaldehyde, and polycyclic aromatic hydrocarbons. Long term smoking of cigarettes is strongly associated with various cancers, including lung cancer, laryngeal cancer, and oral cancer.
Experimental research and statistical data
Comparison of nicotine intake between e-cigarettes and traditional cigarettes
Nicotine intake in e-cigarettes:
According to a study, the average person using e-cigarettes may consume about 96 milligrams of nicotine per day. However, there are significant differences in this value between e-cigarettes of different brands and nicotine concentrations. For example, an electronic cigarette liquid with a nicotine concentration of 20mg/ml, if a person smokes 5ml in a day, they will consume 100mg of nicotine.
Nicotine intake in traditional cigarettes:
For traditional cigarettes, on average, each cigarette contains 1.1mg of nicotine. If a person smokes 20 cigarettes a day, they will consume 22mg of nicotine per day. Considering that not all nicotine is absorbed by the body, the actual amount of nicotine intake may be slightly lower.
From this, it can be seen that although the nicotine concentration of e-cigarettes may be higher, their daily nicotine intake can be regulated compared to traditional cigarettes. Users can choose e-cigarette solutions with lower nicotine concentrations to reduce nicotine intake.
The health effects of long-term use of electronic cigarettes and traditional cigarettes
Long term health effects of e-cigarettes:
Long term use of electronic cigarettes may cause irritation to the mouth and throat, respiratory problems, hypertension, and cardiovascular disease. Some preliminary studies suggest that e-cigarettes may increase the risk of heart disease, especially among young people.
The long-term health effects of traditional cigarettes:
The health risks of traditional cigarettes have been widely studied and confirmed. Long term smoking is associated with various diseases, including lung cancer, cardiovascular disease, chronic obstructive pulmonary disease, and stroke. In fact, according to data from the World Health Organization, smoking is one of the leading causes of premature death, resulting in over 7 million deaths annually.
