Washington D.C. , May 17: New research has claimed that the people who drink more coffee are more sensitive to its odour and can sniff out even tiny amounts of coffee quickly as compared to non-coffee drinkers.

 According to the research published in the ‘Experimental and Clinical Psychopharmacology’, habitual coffee drinkers are not just more sensitive to the odour of coffee and faster to identify it, but the more they crave for coffee, the better their ability to smell becomes.

It is for the first time that evidence has been found to prove coffee addicts are more sensitive to the smell of coffee.

The results could open the door to potential new ways of using aversion therapy to treat people addicted to substances with a distinct smell, such as tobacco and cannabis.

“We found the higher the caffeine use, the quicker a person recognised the odour of coffee,” said Dr Lorenzo Stafford, who led the research.

“We also found that higher caffeine users were able to detect the odour of a heavily diluted coffee chemical at much lower concentrations, and this ability increased with their level of craving. So, the more they desired caffeine, the better their sense of smell for coffee became,” Stafford continued.

“We have known for some time that drug cues (for example, the smell of alcohol) can trigger craving in users, but here we show with a mildly addictive drug, that craving might be linked to an increased ability to detect that substance,” Stafford added.

“Caffeine is the most widely consumed psychoactive drug and these findings suggest that changes in the ability to detect smells could be a useful index of drug dependency,” said Stafford.

The team wanted to examine if there were any differences in the ability of people to smell and respond to the odour of coffee, depending on whether or not they were big coffee drinkers.

The research was based on two experiments.

In the first experiment, 62 men and women were divided into those who never drank anything containing caffeine; those who consumed moderate amounts (70-250mg, equivalent to 1-3.5 cups of instant coffee a day); and those who consumed a high amount (300mg, equivalent to 4 or more cups of instant coffee a day).

Each person was blindfolded and to test their sensitivity to the smell of coffee, they were asked to differentiate very small amounts of the coffee odour from odour blanks, which have no smell.
