Tobacco and Nicotine
Tobacco comes from the leaves of the tobacco plant. It contains a drug called nicotine which is highly addictive. It's nicotine that gives smokers their 'hit'.
Slang: Fags, rollies, smokes, ciggies
The effects
Smoking any drug gets it to the brain quickly. When a smoker inhales, the nicotine reaches the brain in around 8 seconds. Regular smokers say it helps them relax and feel less hungry.
Chances of getting hooked
Nicotine is a highly addictive drug. Smokers can get hooked very quickly and it can take years and a huge effort to kick the habit. Not many people are able to remain occasional smokers.
The law
It's illegal for shopkeepers to sell tobacco or tobacco products to anyone under 18.
Appearance and use
The leaves of the tobacco plant are dried then rubbed to produce a brown, flaky mixture. It can be bought loose as rolling tobacco or in ready-made cigarettes. Tobacco is most often smoked but some people chew it.
Cost
The cost depends on the scale of a smoker's habit. As a guide, smoking 20 a day for five years will cost £8000.
