Why is Using Tobacco So Addictive?

If you've ever smoked and tried to quit, you know it's a challenge.

The urge to continue can be very strong, and there are a number of reasons for that: Brain chemistry


  • Nicotine is a powerful drug that affects mood, focus and thinking.
  • Behavioural conditioning: In just 7 seconds, a puff of nicotine begins to calm a smoker's brain. The brain gets used to hundreds of nicotine 'hits' each day - and may have trouble calming down without them.
  • Smoking is driven by stimulus-response behaviour; for example, the smell of a cigarette or a cup of coffee can automatically produce a strong urge to smoke.
  • Psychology: A lot of smoking is done automatically, without us really thinking about it.
  • Smokers often feel they need a cigarette to feel right or to think clearly.
  • Social Aspects: People with a family history of depression, schizophrenia, attention deficit disorder or other conditions may have a harder time stopping smoking.
  • Smoking is a social ritual for many people, shared with family, friends or co-workers. When other people light up, it often feels natural to join them.
