Drug use can hurt all parts of your body and cause health problems that don't go away.

Drug use, including smoking, can lead to diseases that can kill you, such as:

  • heart disease
  • stroke (brain injury from a blood clot)
  • cancer
  • HIV/AIDS
  • hepatitis (a liver disease)
  • lung disease

A person high on drugs is more likely to have accidents while driving, at work, at home, at parties—anywhere.

Drug use can make people angry and violent. They can hurt themselves as well as other people.

Drug use can make people with depression feel worse—sometimes so bad that they want to end their own lives.

Drug overdoses can kill people.
