It is already known that nicotine augments one's capability to think, perform and take tests. Now, according to researchers, it improves our memory function, too.

Thus far, outcomes about nicotine's effects on promoting human recital were mixed.

According to Dr. Stephen Heishman, a researcher with the National Institute on Drug Abuse, formerly, scientists kept doing researches on the effects of nicotine and human functioning without considering the drug's unkind withdrawal effects.

In its place, the researchers ask study participants to go eight or 12 hours without smoking before examining their brain functioning.

According to Stephen, it was not shocking that as soon as nicotine was administered in those cases, performance bettered.

"Without knowing what their baseline level of performance is, you can''t really say whether that increase is a true increase or whether you''re just bringing that person back to their baseline," Heishman told Discovery News. "Those early studies didn''t provide the pre-deprivation performance, [as in], what''s their performance when they''re normally smoking?"

As a result, Heishman and fellow workers researched all the literature they could discover on nicotine and recital published between 1994 and 2008.

Their outcomes were issued online in the journal Psychopharmacology.

"We knew that the effect on attention was well known, but I was somewhat surprised about the effects on memory," Heishman said. "Smokers say that one of the reasons that they smoke is to help them concentrate, focus on tasks and do their work, and obviously a lot of our daily work involves memory. So on the other hand, I guess it shouldn''t be too surprising." (With Inputs from Agencies)
