- Tobacco contains nicotine, which is a powerful and highly addictive substance.
- Smoking delivers nicotine to the brain very rapidly and effectively, bringing on the rapid onset and maintenance of addiction.
- Nicotine dependence consists of both physical and behavioural components.
- Tobacco use triggers the release of dopamine – a chemical in the brain that is associated with feelings of pleasure (relief of withdrawal symptoms).
- Persons who smoke need greater and greater amounts of nicotine to achieve the same levels of satisfaction.
- Further smoking alleviates the withdrawal symptoms that set in as soon as the effects of nicotine wear off.
