Ever tried taking smart drugs to perform better inexams? They certainly work. Before last summer's exam, a few of my mates,merely out of curiosity, took a considerable amount of Modafinil, a drugnormally used for narcolepsy(嗜眠发作症). Guess what? WhileI was feeling sleepy, bored by revision, my mates were more focused.

Modafinil is a smart drug that gives a user a feelingof staying awake for hours. It also sharpens the mind, improves memory andhelps problem-solving.

But it does more than just keeping you awake. Itdisturbs your mental system, making you desperate to do what you are doing. Youjust don't want to do anything else but revise all the time non-stop.

A recent study discovers that healthy people use smartdrugs, like Modafinil, to get down to and complete tasks they have been puttingoff, because these tasks seem more enjoyable when taking these drugs. Thismight sound like what a stressed student desires. However, the pills have arange of side-effects.

"At present no evidence shows that these drugsare safe in healthy people," as a medical expert puts it, "Orderingonline, though easy, is a dangerous way to obtain drugs. You never know whatyou're actually purchasing. "

In my experience, Modafinil changes people's behaviourtoo. Over those weeks my friends became different people—in turn aggressive,cold. Even eating became "a waste of time" and so did conversation.

A BBC survey found that of those who had tried smartdrugs before, 92% would do so again. My friends say they'd happily do sowithout considering the practice a form of cheating.

I admit I was curious—but not enough to try it. Seeingthe strange behaviour of other users, I feel a little bit upset and scary.Modafinil may promise to change your grades, but it might also change the wayyou act. Don't say you haven't been warned!
