Many people who have drug problems also have a mental health problem, such as:

  • Depression, which makes them feel very sad and tired.
  • Anxiety, which makes them feel nervous, worried, and afraid.
  • Bipolar disorder, which makes their moods change back and forth. They might be full of energy, excited, or even angry, and then feel sad, tired, and hopeless.
  • ADHD (attention-deficit/hyperactivity disorder), which makes it hard to pay attention, sit still, and not act out.
  • Antisocial personality disorder, which makes it hard to have good relationships and care about other people's feelings.

And people with mental health problems like these are likely to also have drug problems. This is partly because drug abuse and mental health problems affect the same parts of the brain.

If someone feels really bad, they might try to make it better by using drugs. Unfortunately, that doesn't usually work for very long. Instead, they may become addicted to drugs and then feel even worse than before.

A drug problem can make a mental health problem worse. And a mental health problem can make a drug problem worse. Someone with both of these problems needs treatment for both at the same time in order to get better.
