Nicotine is the primary agent of regular and e-cigarettes, and is highly addictive. It makes you want to smoke and you suffer from withdrawal symptoms if you ignore the urge. Regardless of how it's administered, nicotine is harmful to young people and young adults. E-cigarettes often contain nicotine and other chemicals that are known to harm health.
For example, users run the risk of exposing their respiratory systems to potentially harmful chemicals in e-cigarettes. Read about these and other risks young people face if they use e-cigarettes. Vaping has risks, regardless of what you vape. Starting to use e-cigarettes, or switching from cigarettes to e-cigarettes, increases the risk of devastating health effects.
The safest option, according to the American Cancer Society, is to completely avoid vaping and smoking. Also known as vaporizers or e-cigarettes, they're much less harmful than cigarettes and can help you stop smoking for good. When vaping, a device (usually a vaporizer or a mod, an improved vaporizer that may look like a USB memory stick) heats a liquid (called vaping juice or electronic liquid) until it becomes a vapor that is inhaled. While second-hand vapor may not affect the lungs in the same way as vaping, it's best to avoid it if possible.
More research is needed to understand the long-term health effects of passive exposure to e-cigarette vapor. Second-hand exposure to e-cigarette vapor is said to be less toxic than second-hand exposure to cigarette smoke.
