Replying to Skiing & olympics

I was talking to my dad about that half pipe skiing should be at the olympics and he told me about a guy a couple of years ago that won a gold medal and they took a drug test and only beacause he took some weed they didn't give him his medal. So I was thinking, if skiing goes to the olympics some skiers could have some problem( tanner and some other guys) because as we all know some of the skiers are not the cleanest...              So what do you think??                                                                     (sorry for my english)
