Substance Addiction FAQ

Substance misuse is more widespread than most people realize. The 2022 NSDUH reports that 24.9% of Americans aged 12 or older used illicit drugs in the past year, and about 10.5% (roughly 29.5 million people) had an alcohol use disorder. These numbers reflect how common substance-related struggles are, and how essential early intervention and treatment have become.

A substance use disorder (SUD) is a medical condition defined by compulsive drug or alcohol use despite negative consequences. In 2022, 17.3% of U.S. adults met diagnostic criteria for a SUD. SUDs range from mild to severe and can involve physical dependence, cravings, withdrawal, and impaired daily functioning.

Once addiction develops, stopping is not a matter of willpower. Drugs and alcohol physically change the brain's reward and stress-response systems. NIDA research shows that chronic substance use reduces natural dopamine production, disrupts impulse control, and strengthens compulsive patterns. This is why professional treatment, especially detox and inpatient care, is often necessary.

Addiction develops through a combination of genetic, psychological, and environmental factors. Genetics alone account for 40–60% of a person's risk, according to NIDA. Trauma, chronic stress, early exposure to substances, mental health disorders, and family history all significantly increase vulnerability.

Withdrawal occurs when the body becomes dependent on a substance and reacts to its absence. It can range from mild anxiety and insomnia to dangerous complications. Alcohol withdrawal can cause seizures and delirium tremens, opioid withdrawal can lead to severe dehydration and heart strain, and benzodiazepine withdrawal can be life-threatening without medical supervision. This is why medical detox is strongly recommended.

Yes. Addiction is recognized as a chronic mental health condition, and it frequently co-occurs with psychiatric disorders. SAMHSA's 2022 national survey found that roughly 21.5 million U.S. adults experienced both a substance use disorder and a mental illness. This combination, known as a dual diagnosis, requires integrated treatment for the best outcomes.

Relapse is common and does not mean treatment has failed. According to NIDA, 40–60% of people treated for substance use disorders experience at least one relapse, similar to other chronic illnesses such as diabetes and hypertension. Relapse signals that ongoing support or adjustments in treatment may be needed — not that recovery is impossible.

Yes. Individuals with a family history of substance use disorders are significantly more likely to develop one themselves. NIDA estimates that nearly half of the risk for addiction is inherited, due to genes affecting dopamine regulation, stress sensitivity, and impulse control.

Substances overstimulate neurotransmitters like dopamine, causing the brain to adapt by reducing its natural production. Over time, areas responsible for judgment, memory, emotion, and decision-making become impaired. These changes make cravings stronger, stress harder to manage, and sobriety extremely challenging without structured treatment.

Yes. Millions of Americans achieve long-term recovery every year. Recovery typically involves medical detox, behavioral therapies, dual diagnosis treatment, relapse-prevention planning, and ongoing support. In a national SAMHSA survey, about 7 in 10 adults who once had a substance use problem reported being in recovery — an important reminder that treatment works.

Professional help is recommended when substance use begins affecting health, relationships, work, mood, or daily functioning. If someone is experiencing withdrawal, using daily, or losing control over their use, it's time to seek medical detox and assessment. Call 866-591-0888 today.
