According to addiction treatment experts, drugs are typically classified into four major categories based on their effects on the central nervous system. This provides a useful framework for understanding what are the 4 main drugs: depressants, stimulants, opioids, and hallucinogens, and how they impact the body and mind. While these classifications are broad, they help distinguish the primary actions and associated risks of many common substances.

Over 140,000 people in the U.S. die from alcohol overuse each year, but fewer people recognize that the answer to, “Is it true that depressants are very similar to the effects of alcohol?” is a definitive yes. The core reason for this lies in their shared pharmacological effects on the brain's central nervous system.

Despite common anecdotes, the notion that certain alcohols are 'uppers' is a widespread misconception, as all types of alcohol, including tequila, are classified pharmacologically as central nervous system (CNS) depressants. The initial feeling of energy or euphoria is due to a temporary biphasic effect, not a true stimulating action.

According to addiction treatment experts, drugs are commonly categorized into four core types based on their primary effects on the central nervous system: depressants, stimulants, opioids, and hallucinogens. Understanding what are the big four drugs and how they impact the body and mind is a powerful tool in preventing and overcoming addiction.

While roughly 80% of adult Americans consume caffeine daily, a common psychoactive substance, many people are unaware of the broad range of **types of drugs that affect the brain**, from prescribed medications to illicit substances, all of which alter normal brain function via neurotransmitters.

In 2024, an estimated 48.4 million people aged 12 or older in the United States had a substance use disorder in the past year [1.3.1]. A crucial step in addressing this public health issue is understanding the answer to the question: **What are the four categories of drugs of abuse?**

Over 90% of alcohol's effect on the central nervous system (CNS) is linked to enhancing the neurotransmitter gamma-aminobutyric acid (GABA), making it a CNS depressant. This fundamental mechanism is shared by several other drugs, so understanding what drug works the same as alcohol involves exploring these different GABA-targeting substances, including their risks and differences.
