Nicotine is the most preventable cause of death. Prevention starts with policy-level measures. This may be in the form of the increased taxation on nicotine products, as well as stricter laws on who can purchase the products, as well as where and when they can be purchased. Another way to prevent nicotine abuse is by educating the community, school students, and families. Informing students about the negative impacts is key. The long-term effects are detrimental, as well as fatal. However, preventative measures can turn those effects around.
