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—will give you a
better understanding of the problem and how to best deal with it.
