Steroid usage affects not only the body but the mind as well. The mental effects of using the drug can be just as dangerous and even more serious than the side effects that are physical. There is a lot of emphasis on the physical changes associated with steroid usage, and the mental aspects of the drug use is often overlooked.
Psychosis is a break with reality. The steroid user doesn't feel connected with the real world and is instead living and thinking in his own world. In this reality he is all-powerful, invincible and capable of anything. It is in the psychosis state that the violence associated with "roid rage" comes into play. When the power or strength of the steroid user is challenged he will do what he can to defend his honor. The steroid user may not even understand or know what he is doing.
Depression is a common side effect and can be so severe that it even leads to suicide. Steroid users often use other drugs to combat the many side effects that accompany the use of steroids, like depression. Insomnia is a common side effect, so the steroid user may abuse sleeping pills. Knowing that she is abusing a drug can then lead to depression, which can just deepen the cycle of drug abuse.
Mania is a feeling of complete euphoria similar to psychosis. During a manic state the user may feel as though he is high. He may also be prone to violence and rash, impulsive decisions. This can negatively effect the social life of the steroid abuser, which can lead once again to depression and abuse of other drugs. In the manic stage, the steroid user may become extremely paranoid about anything and everything. He may feel challenged when no challenge is present. This can lead to violence and loss of social relationships.
