Can prescription drugs cause addiction?

Yes, prescription drugs can cause addiction. Certain medications affect brain systems involved in reward, motivation, and self-control in ways similar to illicit substances. When misused—or sometimes even when used as prescribed over time—they can lead to a substance use disorder.
The risk varies by medication type. Opioids, benzodiazepines, and stimulants are among the most commonly associated with addiction. Factors such as dose, duration, individual vulnerability, and co-occurring mental health conditions all influence risk.
Addiction to prescription drugs follows the same underlying pattern as other substance use disorders, including impaired control, craving, and continued use despite harm.
