Substances, such as alcohol, cannabis, stimulants, and opioids, are psychoactive drugs that may change an individual’s brain function and structure after chronic use. This can result in cognitive and behavioral changes and deficits that may remain even after someone stops using. A dissociative drug developed as an intravenous anesthetic that has been discontinued due to serious adverse effects. Dissociative drugs are hallucinogens that cause the user to feel detached from reality.
Here are a few things a person can consider when seeking treatment for SUD. A hallucinogen found in disk-shaped “buttons” in the crown of several cacti, including peyote. A hallucinogen manufactured from lysergic acid, which is found in ergot, a fungus that grows on rye and other grains. LSD is an abbreviation of the scientific name lysergic acid diethylamide. However, it can also reduce a person’s ability to think rationally and lead to impaired judgment. Over time, an individual can develop a tolerance to or dependency on alcohol.
Yet with repeated use of the drug, the circuit adjusts to the drug’s effect, reducing sensitivity and making it hard to receive other forms of pleasurable stimulation. SUD can affect several aspects of a person’s physical and psychological health. However, effective treatment for SUD should address all of a person’s mental and physical health needs. Opioids can cause euphoria and are often used nonmedically, leading to overdose deaths.
Hallucinogenic (psychedelic) drugs
The converse process (up-regulation) occurs in some instances when receptor antagonists are administered. Receptors for many hormones and neurotransmitters have been isolated and biochemically characterized. All these receptors are proteins, and most are incorporated into the cell membrane in such a way that the binding region faces the exterior of the cell. This allows the endogenous chemicals freer access to the cell. Until the mid-19th century the approach to drug therapeutics was entirely empirical. This thinking changed when the mechanism of drug action began to be analyzed in physiological terms and when some of the first chemical analyses of naturally occurring drugs were performed.
- Derived from the poppy plant, opioids are often prescribed to patients who are suffering from intense pain.
- Examples of injectable drugs are heroin (which can also be smoked), and stimulants such as cocaine and amphetamines (which can also be taken orally).
- People sometimes use these as recreational drugs, as they can give a person a “rush” of euphoria and increase energy and alertness.
However, these drugs can still have adverse consequences with excessive or improper use. For example, it is dangerous for a person to drive while under the influence of alcohol or misuse prescription medications. MDMA, also called molly or ecstasy, can have both stimulant and hallucinogen effects.
Opioids are powerful painkillers that can give you a sense of euphoria. Doctors typically prescribe opioids to people experiencing severe pain. Pharmacologists group drugs into different categories depending on how they affect the body after use. Some drugs slow down bodily functions, while others speed them up. The seven different types of drugs are categorized based on their effects. Each type of drug has its own set of characteristics and dangers.

Some of these experiences can feel pleasurable and profound, while others can feel frightening. From the common to the rare, here’s 5 keys to going alcohol-free a list of different types of drugs and what they do. Because of this, these drugs are prescribed for anxiety or insomnia.

Cannabis, also called weed, is a type of psychoactive drug that can have the effects of a depressant, stimulant, or hallucinogen. Heroin is an illegal drug that binds to opioid receptors in the brain, causing a “rush” of pleasurable sensations. While not all psychoactive substances are illegal, a person can misuse any of these substances. Dissociative drugs work by interfering with the brain’s receptors for glutamate. This chemical plays a significant role in cognition, emotionality, and pain perception. As the name implies, the drug affects a person’s sensory perceptions, causing hallucinations.
Such mechanisms are common for neurotransmitters that act very rapidly. Examples include the receptors for acetylcholine and for other fast excitatory or inhibitory transmitter substances in the nervous system, such as glutamate and gamma-aminobutyric acid (GABA). Drug, any chemical substance that affects the functioning of living things and the organisms (such as bacteria, fungi, and viruses) that infect them. Pharmacology, the science of drugs, deals with all aspects of drugs in medicine, including their mechanism of action, physical and chemical properties, metabolism, therapeutics, and toxicity. This article focuses on the principles of drug action and includes an overview of the different types of drugs that are used in the treatment and prevention of human diseases. For a discussion of the nonmedical use of drugs, see drug use.
Prescription opioids
Like stimulants, depressants also impact the body’s CNS but with the opposite effect, making users feel as if things are “slowing down.” Thus, they are often called “downers” on the street. When you understanding the dangers of alcohol overdose use cocaine, you may talk, move, or think very fast.

Like nicotine and alcohol, an individual can build up a tolerance to caffeine, which means they need to consume more to feel its effects. This can lead to dependency and withdrawal symptoms when a person stops taking it. This drug affects everyone differently, but common effects include an increased appetite, euphoria, and relaxation. Some people might also have altered senses, for example, seeing brighter colors.
