3．Ever tried taking smart drugs to perform better in exams？They certainly work．Before last summer's exam，a few of my mates，merely out of curiosity，took a considerable amount of Modafinil，a drug normally used for narcolepsy（嗜眠發(fā)作癥）．Guess what？While I was feeling sleepy，bored by revision，my mates were more focused．
Modafinil is a smart drug that gives a user a feeling of staying awake for hours．It also sharpens the mind，improves memory and helps problem-solving．
But it does more than just keeping you awake．It disturbs your mental system，making you desperate to do what you are doing．You just don't want to do anything else but revise all the time non-stop．
A recent study discovers that healthy people use smart drugs，like Modafinil，to get down to and complete tasks they have been putting off，because these tasks seem more enjoyable when taking these drugs．This might sound like what a stressed student desires．However，the pills have a range of side-effects．
"At present no evidence shows that these drugs are safe in healthy people，"as a medical expert puts it，"Ordering online，though easy，is a dangerous way to obtain drugs．You never know what you're actually purchasing．"
In my experience，Modafinil changes people's behavior too．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 smart drugs before，92% would do so again．My friends say they'd happily do so without considering the practice a form of cheating．
I admit I was curious-but not enough to try it．Seeing the strange behavior of other users，I feel a little bit upset and scary．Modafinil may promise to change your grades，but it might also change the way you act．Don't say you haven't been warned!
