You may start your report with something like this..

Sports has been a part of our culture from a long time and sports champions have been highly respected. The fame and glory associated has attracted many to try their luck. And as in all fields, some have tried the short cuts as well, performance enhancing drugs being one of them.

... I think this gives a good entrance to your paper because correlation between performance drugs and sports is very strong. You can start your introduction with this idea and it should be followed by a brief introduction about performance drugs.

Then move on to body paragraphs by expanding the points in each para. In the conclusion you can sum up everything and state your findings/ opinion about performance drugs.

Thanks for the help
