Kijavítanátok ebben az angol levélben az esetleges hibákat?

In my opinion, use of drogs and doping in sport is a huge problem. I think a lot of sports could be affected, such as swimming, athletics, football, basketball, handball, cycling or even Moto GP and Formula 1 too. If I brought the rules of the doping controls, I would prescribe stricter and frequent controls because in that way we could filter those sportsmen who use drugs. It would be really useful because we don’t just filter the frauds but we can save their health, because these dopings are very harmful. If they couldn’t use drugs, they would be healthier. I think both the doping users and the regulators are responsible for this. They shouldn’t use drugs and the leaders should bring strict rules.

Előre is köszönöm :D
