Many of the side effects of steroids can be seen from someone’s outward appearance changes or through their behaviors. Some long-term effects of abuse cannot be observed. Although steroid use does not trigger the same intense, immediate response in the brain as another substance like cocaine, it can create changes to the brain over time. These changes can impact the production and supply of certain chemicals in the brain called neurotransmitters.
These changes in the brain can lead to changes in mood and behavior in the person. In the long-term, anabolic steroid abuse can cause:
- Anger and aggression (“roid rage”).
- Heart attack.
- Kidney failure.
- Tumors in the liver.
- Blood-borne diseases from injection use.
