Heroin is an opiate. It is comes from morphine, which is made from the poppy plant. Heroin is therefore a derivative of morphine.
Heroin acts on the central nervous system. It is both a depressant and a hallucinogen, which numbs the brain, slows the body down and affects the senses and the perception of reality.

Heroin use quickly leads to addiction.
Heroin causes psychological dependence, which means that you need to take the drug more often in order to feel better about yourself, relax, calm down, feel stimulated or have the courage to face problems.
Heroin also causes physical dependence, which is a need created by the body’s addiction to the effects of the drug. If you try to go without it, you may experience varying degrees of physical reaction, such as:
- Goosebumps, chills
- Nausea and vomiting
- Diarrhea, cramps, abdominal pain
- Anxiety, irritability

- Experience problems at school or at work
- Lose interest in maintaining relationships with people who do not use the drug
- Isolate yourself
