Drug addiction is a chemical dependency on a substance, such as prescription or illicit drugs. Men, women, and children can suffer from this condition. Addiction can develop quickly or can take years to occur. In all cases, treatment is necessary.
Drug overdose remains a major public health issue. The Centers for Disease Control and Prevention (CDC) reported 79,384 overdose deaths in the United States in 2024, showing the need for timely care.
Understanding what drug addiction is will help you to get the support you need or give you guidance on how to help a loved one. FHE Health in South Florida provides confidential treatment programs for all forms of addiction.

Defining Drug Addiction — What Is Drug Abuse?
Drug addiction is a disease that impacts a person’s brain and behavior. Long-term drug use can lead to a loss of control over taking the drug and a physical inability to stop using the substance, even if you want to.
Drug abuse can begin from experimental or recreational use of a substance, in social situations or in private. When this type of recreational use occurs, the “feel good” experience encourages people to continue using that drug more frequently.
In others, drug addiction begins with prescribed medication. For example, you may be prescribed a painkiller to help you after an injury, but the drug’s addictive qualities cause you to become dependent on it just to get through the day.

What Types of Drugs Are Addictive?
An addictive drug encourages either physical dependency, behavioral changes or both. The many drug classes are generally defined based on how the substance affects its users. Some of the most addictive drugs include:
Stimulants
A stimulant causes the drug user to feel more alert and full of energy. Some of these drugs are commonly prescribed to treat ADHD or asthma. However, stimulant drug abuse can occur when a person uses it to stay awake or to perform better athletically. Some common stimulants include:
- Adderall
- Caffeine
- Ritalin
- Cocaine
- Synthetic marijuana
- Ecstasy
- Methamphetamines
Depressants
Depressants work to help slow down the body, which is why they are also called downers. Medical professionals prescribe these drugs to help with conditions such as anxiety and obsessive-compulsive disorder. They create a sedative-like experience, which makes them attractive to some users. A few examples of depressants include:
- Valium
- Barbiturates
- Rohypnol
Hallucinogens
Hallucinogens change the way the brain communicates, causing more intense changes to emotions and perceptions, often including hallucinations. These drugs can be highly addictive because of the high they create. Common examples include:
- LSD
- Salvia
- Peyote
- Psilocybin
Dissociatives
Dissociatives are a highly dangerous type of hallucinogen. Long-term use can be life-threatening. These drugs can be attractive because they create a change in a person’s brain chemistry, letting users escape from daily life. Examples include:
- Ketamine
- Dextromethorphan
- Nalorphine
- Opiorphin
Opioids
Opioids, both prescription-based and illicit, are one of the fastest-growing causes of drug overdoses today. These drugs work as painkillers and can create a sense of euphoria, making them highly addictive. Common examples include:
- Oxycontin
- Hydrocodone
- Morphine
- Percocet
Behavior and Physical Dependency Explained
Over time, the body develops a tolerance for the drug being used and needs more to get the same type of outcome or high. Addiction’s physical dependency also leads to withdrawal symptoms when a person stops using their drug of choice, which can be highly painful and even life-threatening in some cases. Physical dependency often requires medical intervention due to the risk associated with withdrawal symptoms.
The behavioral addiction can precede a physical dependency and stand alone as the driver of non-substance-based addictions. Behavioral addiction is the reward for a repeated process. An action can trigger a dopamine reward, creating the desire to repeat it. This is the basis of gambling or shopping addiction. This factor can play into substance abuse and it is reinforced when there is a physical withdrawal from an external chemical.

What Is a Drug Overdose?
Illicit drug use comes with the risk of a drug overdose, which occurs when the body cannot eliminate that amount of the substance or tolerate it. During an overdose, the patient may experience trouble breathing, unconsciousness, and, in some cases, it can be fatal. Overdoses are dangerous and require immediate medical intervention.
An overdose can happen accidentally if a person takes more of a drug than they should. The body cannot process the drug, and organs begin to fail. Signs of an overdose can include chest pain, paranoia, disorientation, confusion, violent behavior, difficulty breathing and seizures.
Signs of Drug Addiction

Drug addiction help can only begin when a person recognizes that a problem exists and takes steps to improve their life. Family members may see signs of abuse such as:
- Intense cravings to use that often block out other thoughts
- Continuing to use a drug that has caused ill effects
- A need to have the drug on a consistent basis
- Not meeting obligations in a work or school environment
- Failing in efforts to not use the drug, even when desired
- Taking larger amounts of the drug over a period of time to get the same results
- Spending money on drug purchases instead of taking care of obligations
- Physical health changes include a lack of energy, significant weight loss or gain and red eyes.
How to Seek Drug Addiction Treatment
Getting drug addiction treatment is an essential step to achieving long-term recovery. Therapy is likely to include a period of detoxing from the drug in a medically secure facility. From there, we offer inpatient and outpatient care.
At our Deerfield Beach rehabilitation center, we create a customized treatment plan that helps you understand your experiences, develop improved coping skills and build essential life skills. Drug addiction treatment provides a safe place for people to understand why they are using, the danger of continuing to do so and how to rebuild their health and relationships.
The first step in getting help for drug addiction is to reach out to our team for a private assessment. We’ll talk with you about your substance use, your overall health and whether you might need medical detox before starting treatment.
Next, we’ll review your insurance, recommend the appropriate level of care, and create a treatment plan that fits you. Whether you live in South Florida or are coming to Deerfield Beach for help, we want to make the process as simple as possible.

Drug Addiction Recovery
Drug addiction recovery is a complex process requiring initial support and long-term care. It’s critical for individuals to work closely with a team to provide one-on-one support and group therapy.
During treatment, you begin to restore parts of your life that addiction changed, such as your health, routines, relationships and sense of purpose. With steady support and a clear plan, our patients learn how to face challenges and avoid slipping back into old habits.
At FHE Health, we see recovery as a journey. We continue to support patients after detox or inpatient treatment. As your needs shift, the next steps in care help you build stability and confidence in daily life.
Recovery often involves lifestyle changes, but it can also mean living longer, rebuilding relationships and achieving more of your goals. Explore the continuum of care we offer here at FHE Health.
Medical Detox For Drug Addiction
For many people, treatment starts with medical detox. During detox, your body gets rid of substances while a clinical team watches for withdrawal symptoms and handles any complications that could become serious or life-threatening.
At FHE Health, medically supervised detox covers evaluation, stabilization, and a smooth move into ongoing treatment. This way, you do not have to stop after withdrawal.
Dual Diagnosis and Co-Occurring Mental Health Disorders
Drug addiction and mental health issues often happen together. You might experience depression, anxiety, trauma, bipolar disorder or other challenges while using substances. Many people use drugs to escape pain or quiet their symptoms, but this usually makes things worse in the long run.
At FHE Health, we focus on the mental and emotional reasons behind substance use. Your care team will review your symptoms, identify any related conditions, and develop a plan to treat both. This approach helps you recognize triggers and learn better ways to cope. Treating both issues together gives you a stronger chance at lasting recovery.
