6. Lead

Lead ranks 6th on our list of top 10 ingredients in cigarettes that are harmful. It is a heavy metal found in cigarettes and is also a neurotoxin, meaning, it is poisonous or destructive to nerve tissue. It interferes with the formation of iron, causing anemia, and leads to constipation, depression, and nausea. The most detrimental consequences of the intake of lead, however, are faced by the nervous system. Lead may not only lead to a decrease in performance and weakness in joints but may hinder and obstruct the development of the brain, especially in children. The functions of the kidneys and the brain are impeded, and in serious cases, death may even occur.
