Substance Use Disorder: Causes, Treatments, and How Medications Help

When someone struggles with substance use disorder, a chronic condition where compulsive drug or alcohol use interferes with daily life. Also known as addiction, it’s not a lack of willpower—it’s a brain disease that changes how reward, motivation, and decision-making work. People don’t choose to become dependent. Over time, repeated use rewires the brain’s chemistry, making it harder to stop even when the consequences are serious.

This is where medication-assisted therapy, the use of FDA-approved drugs to reduce cravings and withdrawal symptoms. Also known as MAT, it’s one of the most effective tools we have. For opioid dependence, drugs like methadone, buprenorphine, and naltrexone help stabilize brain function so people can focus on recovery. For alcohol use disorder, medications like disulfiram, acamprosate, or naltrexone reduce the urge to drink. These aren’t replacements—they’re tools, like insulin for diabetes. You wouldn’t tell someone with diabetes to just stop needing insulin. Same here.

But meds alone aren’t enough. support groups, peer-led communities that offer accountability, shared experience, and emotional safety. Also known as 12-step programs, they’re often paired with treatment. Research shows combining meds with counseling or group support cuts relapse rates by half. That’s why the best recovery plans don’t just treat the body—they rebuild a life.
