Nicotine
Tobacco products and electronic cigarettes, the most popular form of nicotine worldwide, have become a public health concern. Leading to an increase in countries' governments' and public health organizations' efforts to regulate its use and sales. With 30 countries currently having banned the purchase of any form of these products. Since 2022 legislation against e-cigarettes  is on the rise as more studies are released. A large contributor to this was the World Health Organization's concerns raised about how secondhand smoke affects children in the home. Highlighting the potential risks of exposure to nicotine, which is known to cause issues in brain development and lead to anxiety disorders, among other health problems. While e-cigarettes have been marketed as a safer alternative to traditional cigarettes, there is still much debate about the potential risks and benefits of these products. As nicotine percentages are higher on average in many forms of e-cigarettes compared to traditional tobacco products.
