La salud bucal no es relativo a la aparición de los dientes, sino que empieza incluso desde la gestación.
Nicotine reaches the brain 8 seconds after inhaling tobacco smoke and is just as addictive as heroin and cocaine.
The series of informational booklets called Mind Over Matter, published by the U.S.-based National Institute on Drug Abuse (NIDA), explains how the brain responds to different drugs, including nicotine; classified as being highly addictive and as the cause of even more disease and death then all other addictive drugs combined.
When a person smokes, the lungs absorb the nicotine, which quickly transfers to the bloodstream and circulates throughout the brain. Here, it imitates the function of different neurotransmitters, which are responsible for sending nerve impulses throughout the body.
Nicotine therefore imitates and affects the function of the neurotransmitters involved in our muscle movements, breathing, heartbeat, ability to learn, memory, mood and, appetite, etc. It can affect the whole body, leading to well-known health risks such as high blood pressure, a reduced sense of smell and taste, cancer, heart attacks and stroke, etc.
Despite the known health risks, smoking tobacco continues to be a common habit as nicotine greatly impacts a neurotransmitter called dopamine. This neurotransmitter is responsible for stimulating feelings of pleasure and gratification, both of which are highly addictive feelings, which explains why quitting is so difficult.
