We’re at a time when drugs of abuse and addiction have become not only problematic in terms of the effects of addiction, but also the overdose risks they create. Learning about some of the most commonly abused drugs, and some of the substances that are most addictive can help people who are struggling with those substances. Drug guides and resources can also be useful for the loved ones of addicts.

Drugs of abuse are ones that have not only addiction potential, but psychoactive properties.

Psychoactive properties mean these substances change how someone using them thinks or behaves.

Not all commonly abused substances and drugs are illegal. Some are available by prescription. Prescription drugs, and in particular opioids, have actually become some of the deadliest substances in the United States through the onset of the opioid epidemic.

Commonly Abused Substances

The following are some of the categories of drugs of abuse that are most commonly utilized in the U.S.


Alcohol is something that’s become part of our culture and celebrations in the U.S., and around the world. People can often casually drink without it becoming a serious problem, but some people do become addicted and struggle with alcoholism. Alcoholism is also known as alcohol use disorder.

Benzodiazepines are central nervous system depressants, available by prescription. One of the most frequently prescribed benzodiazepines is Xanax. This drug class is used to treat short-term symptoms of anxiety, panic disorders, and insomnia. Benzodiazepines also have the potential to be habit-forming, particularly when they’re used for more than a few weeks.


Cocaine is a stimulant drug, and it’s derived from the leaves of a plant native to South America. When someone uses cocaine, it causes a rush of energy, euphoria, and feelings of confidence. Cocaine also has many negative effects. The use of this stimulant drug can cause addiction, as well as severe cardiac symptoms and even sudden death.


While many of the most abused opioids are prescription pain medications, heroin is an opioid not available legally. Heroin has effects similar to morphine, and it’s a naturally-derived opioid. Heroin is often injected into the bloodstream, and it creates a sense of relaxation and euphoria. Unfortunately, heroin also slows breathing and other essential functions, which can cause a fatal overdose.

Marijuana is a substance that is met with controversy in many ways. A lot of states have moved to make it legal not only for medical purposes but also recreationally. However, it’s still illegal federally and some critics do feel there is an abuse and addiction potential that occurs with marijuana.


Methamphetamine is a powerful, highly addictive stimulant drug. It can be sold illegally as a white powder or by prescription as a pill. Methamphetamine can also come in chunks that look like glass or blue-white rocks. This is known as crystal meth.

Prescription Opioids

Prescription opioids are especially problematic in the U.S. right now. Since the 1990s there has been a surge in the prescribing of these medications. In recent decades, the result has been a tremendous increase in addiction disorders as well as overdose deaths. Prescription opioids may be effective at relieving pain, but their addiction potential and the side effects are similar to heroin.

Prescription Stimulants

Prescription stimulants are often used to treat ADHD symptoms, but they’re also abused recreationally. Prescription stimulants include brand-name drugs like Adderall, Concerta, and Ritalin. These drugs can have side effects similar to cocaine. For example, they can increase energy, attention, sociability, blood pressure, heart rate, and breathing. They also have addiction potential.
