Heroin activates regions of the brain that are responsible for producing both pleasurable sensations and physical dependence. It depresses the central nervous system and makes the user appear tired, drowsy or drunk rather than energetic or hyperactive.

Heroin abusers have a need for persistent, repeated use of the drug because of the painful physical withdrawal symptoms that result from non-use. These symptoms are typically quite severe and include panic attacks, tremors, sweating, nausea, muscle cramps and insomnia.

Abusing heroin leads to serious health risks, including fatal overdose, spontaneous abortion, collapsed veins and risky behavior that may lead to HIV/AIDS, hepatitis and other infectious diseases. Users are also at high risk of pulmonary and respiratory complications.

Heroin has a high potential for abuse and is classified as a Schedule I drug in the United States.

What heroin does to your

Brain—Enters the brain quickly and slows down thinking, reaction time and memory. After a short period of use, many addicts no longer experience the high—they use heroin only for relief of painful withdrawal symptoms.

Heart—Chronic users may develop collapsed veins and infection of the heart lining and valves. Pulmonary complications may also result from the poor health condition of the abuser.

Liver—Chronic users may develop liver disease. Street heroin has additives that do not readily dissolve and clog the blood vessels that lead to the liver. This can cause infection or even death of small patches of cells in the organ. Hepatitis B and C are very prevalent in IV drug users and can cause fatal liver failure.

Lungs—Heroin depresses the central nervous system and may slow breathing to the point of respiratory failure. Pulmonary complications, including various types of pneumonia, may also result.
