Can e-cigarettes cause anxiety?

Nicotine, the main component in e-cigarettes, may affect the user's psychological state. Although nicotine may bring a brief sense of relaxation upon initial intake, as it is consumed in the body, it may cause users to feel more anxious and nervous. Long term use of e-cigarettes may lead to nicotine dependence, further increasing the risk of anxiety.

The main components in electronic cigarettes
nicotine
Nicotine is one of the main components in electronic cigarettes and is commonly used to simulate the experience of traditional cigarettes. It is extracted from tobacco plants and is stimulating and addictive. The concentration of nicotine varies in different electronic cigarette liquids, ranging from low to 0mg/ml to high to 50mg/ml or higher. Although nicotine helps many people quit smoking, it also has some potential health risks, especially for minors and pregnant women.
Liquid substrate
The liquid substrate is another major component in electronic cigarettes, typically composed of plant glycerol (PG) and/or sucrose alcohol (VG). These components provide a carrier for nicotine and spices, and determine the taste, smoke yield, and power of e-cigarettes.
Plant glycerol (PG): This is a colorless and odorless liquid commonly used in food, medicine, and cosmetics. PG can produce better throat sensation and more throat burning.
Sucrose alcohol (VG): It is more viscous than PG and can produce more steam. Due to its high viscosity, it may cause blockage in some electronic cigarette devices.
The quality and price of liquid substrates may vary by brand and manufacturer, but generally speaking, the price of 10ml of high-quality e-cigarette liquid ranges from $3 to $10.
Spices and other additives
Spices are an important component in electronic cigarettes, providing users with a wide range of flavor choices, from traditional tobacco flavors to fruits, desserts, beverages, and more. These spices are usually made from food grade ingredients, but that doesn't mean they are all safe when inhaled.
In addition to spices, some e-cigarette liquids may also contain other additives such as pigments, sweeteners, or other chemicals to enhance the taste, color, or stability of the product.
The definition and manifestation of anxiety
What is anxiety?
Anxiety is an emotional response that typically involves worry or fear of future events. It can be a response to specific situations, such as exams, job interviews, or upcoming major events, or it can be a general concern about unclear or uncertain things. Unlike temporary tension or worry, anxiety is a persistent feeling that may affect an individual's daily life. In some cases, if left untreated, anxiety may lead to more serious mental health problems.
Common symptoms of anxiety
The symptoms of anxiety can range from mild to severe, involving physical, psychological, and behavioral responses.
Physical symptoms: This includes accelerated heartbeat, sweating, trembling or trembling, shortness of breath or feeling suffocated, chest pain, nausea or diarrhea, and dizziness or dizziness.
Psychological symptoms: This includes persistent worry, fear, panic, excessive worry about daily affairs, susceptibility to being scared or scared, and feeling that things are losing control.
Behavioral symptoms: This includes avoiding certain places, activities, or people, frequent ritualistic behaviors (such as washing hands) to alleviate anxiety, or prolonged avoidance of certain things or decisions.
The relationship between e-cigarettes and anxiety
The effect of nicotine on anxiety
Nicotine is an irritating chemical found in tobacco and e-cigarettes. Many people believe that nicotine can alleviate anxiety and stress, which is also one of the reasons why some people start smoking or using e-cigarettes. However, although nicotine may bring a brief sense of relaxation, it is not an effective way to alleviate anxiety in the long term.
When the body ingests nicotine, it stimulates the central nervous system, leading to the release of "pleasure chemicals" such as dopamine. This feeling may be satisfying, but it is short-lived. As nicotine is consumed, the body may feel more anxious and nervous, prompting users to use e-cigarettes or tobacco products again. This leads to a cycle where nicotine becomes a way to temporarily alleviate anxiety caused by discontinuing nicotine intake, thereby increasing dependence on nicotine.
Research evidence: the association between e-cigarettes and anxiety
In recent years, many studies have attempted to determine the relationship between e-cigarette use and anxiety. Some studies have found that e-cigarette users have higher levels of anxiety compared to non-smokers. Although these studies provide valuable insights into the relationship between the two, more research is still needed to determine the exact nature and reasons for this connection.
A study conducted in 2020 found that anxiety symptoms among e-cigarette users were related to nicotine intake, with high intake users reporting higher levels of anxiety. This may be due to the physiological effects of nicotine, or other factors related to the use of e-cigarettes, such as health concerns or social pressure.
On the other hand, some users report turning to e-cigarettes because they are safer compared to traditional tobacco products, which reduces their concerns about health consequences and anxiety.
