Some people are able to use recreational or prescription drugs without ever experiencing negative consequences or addiction. For many others, substance use can cause problems at work, home, school, and in relationships, leaving you feeling isolated, helpless, or ashamed.

If you’re worried about your own or a friend or family member’s drug use, it’s important to know that help is available. Learning about the nature of drug abuse and addiction—how it develops, what it looks like, and why it can have such a powerful hold—gives a better understanding of the problem and how to best deal with it.

Drug abuse and addiction is less about the amount of substance consumed or the frequency, and more to do with the consequences of drug use. No matter how often or how little you’re consuming, if your drug use is causing problems in your life—at work, school, home, or in your relationships—you likely have a drug abuse or addiction problem.
