Heroin is a depressant. It acts as a sedative. Heroin suppresses the nervous system, reflexes. Heroin reduces cardiac activity, breathing; a person can start to dust. With the use of heroin, a wave of happiness, heat, dyslexia, and relaxation is flooded. The first time you use your heroin, a person may feel bad, especially if he or she is given a vein. When the heroin is coated, the skin is red; the mouth is dry, you feel very low. Later, the user goes into a semi-conscious state, when it’s hard to think or do anything.

Side effects

People often need to increase their dose every time they are taking heroin. Becoming addicted, a person is looking for a new dose every few hours — the body experiences severe withdrawal symptoms, such as shaking, sweating, anxiety, bone and muscle pain, inguinal hernia, nausea, and leg and arms seizures. This is most pronounced between 48 and 72 hours of abstinence. Everything goes about a week later. The signs of abstinence still have a very high mental urge for drugs. Heroin users risk becoming infected with hepatitis; HIV that causes AIDS. When you buy heroin, you never know what purity it is, so there is also the risk of overdose. Heroin is easy to overdose with alcohol or other depressants.

Overdose is characterized by clinical syndromes:

  • Presence of consciousness, from sleepiness to coma.
  • Eye pupils are small.
  • Clogged breathing – 4-6 times per minute.
  • Decreased arterial blood pressure, slow pulse.

Only after commencing use or in unintentional cases:

Heroin actively inhibits the brain, affects body reflexes such as coughing, breathing, and pulse. It makes a person sleepy, unable to feel anxiety and pain. Since heroin is often administered by injection, there is a risk of overdose. This may be the cause of loss of consciousness and, more rarely, of death from air shortages. The risk of overdose increases with the use of other depressants at the same time.

For continuous use:

For those who take heroin often, an ever-increasing dose is required for the same effect every time. A person becomes psychologically addicted to drugs, whose buying becomes more important than anything. Persons who regularly use heroin say that it causes a feeling of warmth and a sense of relaxation. Sometimes there is another effect – nausea and vomiting, loss of appetite. Sudden abandonment of heroin results in cramps, muscle cramps, and flu symptoms. All this disappears in just a few weeks.

Abstinence syndrome

Severe symptoms of abstinence begin with a drug user who has not received heroin for a long time. The syndrome starts 6-12 hours after the last dose, at the latest 24-48 hours. This reaction of the body is directly related to the effect of diacetylmorphine on the brain. By interacting with opioid receptors, it inhibits the production of endorphins naturally and reduces receptor sensitivity. If you stop using drugs, a complete or partial pain control system is disconnected. After a while, the body begins to produce endorphins, the body’s physical condition normalizes. The physical dependency on drugs is reduced or, in rare cases, disappears altogether. The psychological dependence remains strong or increases.

Abstinence syndrome manifests itself in unpleasant physical sensations – abnormal breathing, sweating, fever, muscle aches and increased pain, enlarged pupils, enhanced reflexes and movements, abdominal cramps, vomiting and diarrhea, insomnia. Irritability, depression can increase. The syndrome lasts 5-7 days, but in specific cases, the duration depends on the length of use of the drug, the dose level, the general state of the organism.
