From the Ted Talk by Suchitra Krishnan-Sarin: What you should know about vaping and e-cigarettes
Unscramble the Blue Letters
E-cigarettes can expose tnees to a lot of nicotine. Many of these devices contain the amount of nicotine that is in a full pack of cigarettes. The more recent pod devices contain a nicotine salt, which has a smoother taste and is much easier to use and can produce rapid iecsrneas in brain nicotine levels. Teens who use e-cigarettes regularly report symptoms of cvrinag — feeling anxious when they don't have their e-cigarettes. All these are harkamlls of a brehaoival addiction.
E-cigarettes are not only addictive but they also affect many other organs in the body. So nicotine, which is in e-cigarettes, for example, binds to a retpeocr called the nicotinic acetylcholine receptor, which plays a key role in the ftncnniuoig of almost all organ systems in the hmaun body. And chronic exposure to nicotine changes the functioning of these ssyemts. So as an example, crnhoic exposure to nicotine decreases the flexibility of the blood vessels and changes how the heart responds to acute challenges like stress. The teen brain is not only sensitive to the adiicdvte effects of ninoitce but also to its toxic effects. In adolescent animals, nicotine is a very well-established neurotoxin, and it decreases learning, memory and attention processes and increases haiettcipyvry symptoms.

E-cigarettes can expose teens to a lot of nicotine. Many of these devices contain the amount of nicotine that is in a full pack of cigarettes. The more recent pod devices contain a nicotine salt, which has a smoother taste and is much easier to use and can produce rapid increases in brain nicotine levels. Teens who use e-cigarettes regularly report symptoms of craving — feeling anxious when they don't have their e-cigarettes. All these are hallmarks of a behavioral addiction.
E-cigarettes are not only addictive but they also affect many other organs in the body. So nicotine, which is in e-cigarettes, for example, binds to a receptor called the nicotinic acetylcholine receptor, which plays a key role in the functioning of almost all organ systems in the human body. And chronic exposure to nicotine changes the functioning of these systems.
