Vaping is the act of inhaling and exhaling vapor produced by the heated nicotine liquid in an electronic cigarette, vape pen, or personal vaporizer.
Vaping has become a popular alternative to traditional smoking in recent years. It has even been marketed as a safer option for smoking cigarettes.
Although some of the health risks associated with vaping appear to be less severe than traditional smoking, there are still risks. They include:
- Nicotine is highly addictive, and exposure during adolescence can harm the developing brain
- E-cigarettes contain chemicals that can cause irreversible lung damage and alter teen brains
- E-cigarettes contain harmful chemicals, such as formaldehyde, which is known to cause cancer, and acrolein, which is used as a weed killer and can cause irreversible lung damage
- Youth who use e-cigarettes are more likely to go on to use traditional cigarettes
- In the short term, e-cigarette aerosol can irritate your lungs, throat, and eyes. It can also make it more likely that you’ll catch colds or get the flu
In addition to these health risks, vaping can cause other harmful effects, including:
- Altered oral microbiome leading to gum disease, tooth decay, oral mucosal lesions, impaired wound healing, dry mouth, and bad breath
- Cavities and gum disease
- Short- and long-term effects on attention, learning, and memory
- Irritability and mood swings
- Insomnia, restlessness, and sleeplessness
- Coughing and wheezing
- Nausea, vomiting, headaches, and dizziness
- Increased risk of seizures, especially in youth
- New onset of seizures
- Severe burns or other injuries due to vape explosions
Vaping among teens has become popular due to several factors, including:
- Some vapes can cost less than regular cigarettes, as well as price incentives or free samples
- Gamification through engaging features, competition, reward systems, and flavors attractive to youth
- Sleek and modern design of devices that feature bright colors to give them a less harmful appearance
- Social influences, such as the use of online or social media strategies
- Positioning products at festivals and within digital games
- Predatory marketing tactics like those used by tobacco companies
