This is largely due to the discernable effects of the drugs on the body — including slowed breathing and heart rate. But the National Institute on Drug Abuse categorizes heroin and prescription opioids in a class of their own.
Opioids activate the opioid receptors in the central nervous system, which can cause respiratory depression. However, opioids act primarily as analgesics, or painkillers, and rarely have depressant effects unless taken at high doses or with other drugs that produce sedation, namely the classical CNS depressants, such as benzodiazepines and barbiturates.
The Drug Enforcement Administration classifies heroin as a Schedule I controlled substance in the United States — meaning it has no medical uses and a high potential for abuse and addiction. Conversely, most central nervous system depressants, such as Xanax and Ambien, have been approved by the FDA for medical use and scheduled according to their risk for abuse.
Various types of drugs can trigger depression, a mood disorder characterized by fatigue, hopelessness and suicidal thoughts, but that does not mean that these drugs are depressants. The National Institute on Drug Abuse explains that CNS depressants slow brain activity by increasing the activity of the chemical GABA, gamma-aminobutyric acid.
In addition to blocking pain, opioid receptors are involved in feelings of pleasure and in controlling heart rate, sleeping and breathing. This means that while heroin dulls pain and offers a rapid and intense rush, it may also impair cognitive functioning, increase sedation, and slow certain autonomic functions, such as those that control a person’s respiratory rate. In other words, it acts as a depressant.
After an initial surge of pleasure or euphoria people who use heroin often experience heaviness in their arms and legs clouded mental functioning. Another side effect of heroin use is “going on the nod,” which is a back-and-forth state of consciousness and semi-consciousness.
People who use heroin chronically can experience many adverse reactions affecting the body and the mind. Mental disorders such as depression can occur with long-term heroin use.

About one-fourth of heroin users will eventually become addicted to the drug, according to the National Institute on Drug Abuse. And nearly one-half of people addicted to heroin will also suffer from depression.
When a person begins to use more and more heroin to achieve the same initial transient “high,” the brain quickly adapts to the constant presence of the drug.
If the person decides to stop taking the drug, the brain will fail to produce or trigger the high levels of pleasure or feel-good signals it was once accustomed to with the increased stimulation of the heroin. This can lead to symptoms of depression as the brain struggles to adjust.
Untreated depression can become worse or interfere with recovery efforts as a person detoxes. Research shows that heroin users who also suffer from depression have a greater risk of overdose, relapse and suicide.
Signs of depression include:
- Low mood without reason
- Sleep problems
- Change in appetite
- Weight gain or loss
- Extreme fatigue
- Feelings of worthlessness and guilt
- Trouble concentrating
- Slowed or accelerated movements
- Feelings of Hopelessness
- Lack of enjoyment in usual activities or hobbies
- Repeated thoughts of suicide or death
The important thing to remember is that the mood disorder depression is not the same as the depression of the central nervous system and not all drugs with depressant properties are classified as depressant drugs.
If you’re facing a heroin use disorder or depression, help is available for both. Do not wait to seek treatment because both of these disorders can lead to severe health consequences. With treatment centers across the country The Recovery Village can help you find effective treatment options for your mental health and substance use problems.
