These days teens think it’s cool to vape and smoke e-cigarettes, not knowing the side effects and dangers of it. Nicotine is highly addictive and can harm brain development. There are many dangers to vaping. Vaping can cause you to lose unnecessary weight; it also causes nausea and vomiting, diarrhea, and breathing difficulties. Did you know that e-cigarettes contain other unsafe chemicals besides nicotine? Those chemicals can damage your brain cells and can cause your brain to stop developing by the age of 25. In my opinion they should not sell any products that contain nicotine; it should be banned in all states to keep teens from ruining their brain cells and also their childhoods. Just say NO to nicotine.
