A cigarette wrap consists of dried tobacco leaves and chemicals that help even combustion. Burning tobacco releases close to 4000 toxic chemicals, including carcinogens like hydrogen cyanide, nitrous oxides, cadmium and lead.

On top of it cigarettes contain tar. It is common knowledge that cigarette stains the teeth and skin, its mostly due to the sticky nature of tar. Also Benzopyene present in the tar is a known carcinogen.

Medulla part of brain is regulating our involuntary life sustaining functions such as breathing, and heart rate.

The medulla oblongata basically detects carbon dioxide (CO2) and Oxygen (O2) levels in the bloodstream and determines what changes need to happen in the body. It can then send nerve impulses to muscles in the heart and diaphragm, letting them know that they need to either step up their game, or slow down a bit.
