Most adults in the UK are aware of the physical health risks of smoking tobacco, but research shows that smoking also affects people's mental health. The biological factors involved in smoking relate to how the brain responds to nicotine. When a person smokes, a dose of nicotine reaches the brain within about ten seconds. At first, nicotine improves mood and concentration, decreases anger and stress, relaxes muscles and reduces appetite. Regular doses of nicotine lead to changes in the brain, which then lead to nicotine withdrawal symptoms when the supply of nicotine decreases.

Voiceover: For one, smoking can cause both immediate and long-term damage. The chemicals in cigarette smoke reach your lungs quickly every time you inhale.

The lungs start to glitch. Four arrows appear pointing the flitching lungs to each phone with an organ on it.
When someone mentions the toll smoking takes on your skin, what is the first thing that comes to mind? Most of us probably think of wrinkles, and with good reason. Some of the toxins in cigarette smoke damage collagen and elastin, which are fibrous components of skin that keep it firm and supple. This damage speeds up skin aging, making smokers more prone to wrinkles on their face and body. Crow's feet are a common type of wrinkling that develops at the outer edges of the eyes.
