This depends on the specific exercise situation. Usually athletes have occupational diseases. Bodybuilding athletes are most likely to suffer from diseases caused by drug abuse-because bodybuilding has not been very strict with illegal drugs, but it has become more strict in recent years, but there are still many athletes who take a lot of steroids and related drugs in peacetime and stop when the competition is near.
Generally speaking, amateurs seldom use drugs because they have no competitive pressure. Correct fitness exercise generally won't have any sequelae.
