Users of steroids and Adderall

The National Football League is not permitted to make public details, when players fail drug tests. It is just affirmed that certain persons have violated anti-doping program. But the League must not disclose which substances have been administered by these sportspersons. So, some football players cheat about products that have resulted in positives.
Why do several football players choose to lie about substances that have been administered by them? Let try to understand.
A lot of football players that fail drug tests say that they have administered Adderall. In fact, they have taken steroids. Why do they affirm that they have tested positive for Adderall? What does Adderall represent? This is a drug which is used for treatment of attention-deficit disorder. But this medicine is applied not just for this clinical need. Sportspersons and bodybuilders use this preparation for performance-enhancing effects.
When it comes to anabolic steroids, they are widely demonized. Numerous journalists, experts, anti-doping officers and ordinary individuals affirm that these preparations are too dangerous. They may cause various severe unwanted results. Steroids are demonized even for several crimes. But when it comes to Adderall, this product is not demonized in the society. So, many football players try to avoid criticism. They don’t want to be demonized for administration of such forbidden products, as steroids. Since users of Adderall are not criticized harshly, football players say that they have failed drug tests because they have administered Adderall.
A football player compared this situation with following cases: those who are caught with cocaine tell others that they have taken marijuana because cocaine is more harshly blamed than the last one.
You should not suggest that every football player who says that he has tested positive for Adderall has actually taken anabolic steroids. But it is possible to conclude that those that administer Adderall are less blamed than those who administer steroids.
