Smoking 'can help create stronger memories'

London: Smoking is injurious to health, everyone knows. Yet, a new study has claimed that it can help create stronger memories.

Researchers, led by Baylor College of Medicine, have carried out the study and found that remembering what happened the night before might be easier for smokers as compared to non-smokers.

According to them, this is because nicotine, the addictive component in cigarettes, "tricks" the brain into creating links between smoking and a feeling of well-being.

They said that events such a drinking alcohol, dining with friends or even driving home from work can act as cues that give people the urge to light up, British newspaper 'The Daily Telegraph' reported.

Lead researcher Dr John A Dani said: "The brain sends a reward signal when we act in a way that contributes to our well-being. However, nicotine commandeers this subconscious learning process so we begin to behave as if smoking is a positive action."

The researchers have based their findings on tests involving the behaviour and recorded brain activity of mice when exposed to nicotine.

The study has appeared in the latest edition of the 'Neuron' journal.
