Smoking is a common and addictive habit, which often means that when a regular smoker attempts to quit they experience withdrawal symptoms caused by a drop in nicotine levels that stimulates the brain.
The withdrawal from nicotine causes feelings of irritability, restlessness, anxiety and hunger. Things like nicotine patches, tablets, lozenges, gum and nasal sprays can be very effective in reducing withdrawal symptoms, by replacing some of the nicotine that you'd get from smoking tobacco.
In addition to withdrawal, smoking also has ill effects on your health, including on your senses of taste and smell, increased risk of stroke, heart attack and cancer as well as conditions like blood pressure, diabetes or asthma.
