What Does Heroin Do to the Brain?
In terms of mechanism of action, heroin is an opiate that attaches to receptors in the brain and produces a rush of intense euphoria. Another heroin effect on the brain is the release of dopamine, a neurotransmitter associated with pleasure and reward. This is the high that addicts crave. The intensity of the rush and the development of side effects depends on how quickly the drug enters the brain. For example, injecting heroin produces an almost instant high and is associated with a number of side effects.
This drug is a central nervous system depressant that slows down functioning of the body. It causes neuronal and hormonal imbalances and deterioration of white matter in the brain. Heroin seizures are not common but may occur if the substance is taken in combination with alcohol or other drugs, for example, heroin and weed.

Factors Affecting Emergence of Side Effects
The intensity of the physical psychological effects of heroin depends on a number of factors. Here are some of the variables that can affect the occurrence and severity of complications:
- Amount used
- Duration of use
- Purity of the illicit substance
- Method of administration (smoking, snorting, injecting)
- Adulterants used to cut the drug
- Contaminants introduced during manufacturing
- Mixing with other drugs or alcohol
- Individual tolerance
Reducing the Risks of Heroin
Can addicts take any special precautions to prevent side effects or reduce heroin effects on the body? Here are some tips:
- Use a pure form of the drug (white powder with a bitter taste). Adulterants and contaminants increase the risk of side effects.
- Avoid injecting the drug. This method introduces the drug directly into the bloodstream, from where it rapidly crosses the blood-brain barrier and binds with opioid receptors in the brain. Injecting also increases the risk of contracting serious illness.
- Do not mix it with other drugs or alcohol.
- Maintain good nutrition and hydration.
Getting Treatment for Heroin Side Effects
Illegal opioid abuse and addiction is a serious medical condition that requires care from experts in chemical dependency and heroin treatment. It is not advisable to attempt detoxification at home without medical supervision. Because of how heroin affects the brain and body, sudden cessation or reduction in drug use can prove dangerous. It is important to seek professional help to cope with withdrawal symptoms. Effective substance abuse treatment planning includes a combination of medication-assisted detoxification and behavioral therapy. Addiction is not the end of the road. The important thing is to get help at a reputed rehab for drug addictions.
