Look for Changes in Personal Appearance

Most drug and alcohol use may cause some change in physical appearance. Few of these in isolation are definitive proof of teenage alcohol use or drug use, but may fit into a larger pattern of symptoms, or act as a way to open up a conversation with your teen.

• Messy, careless appearance
• Poor hygiene
• Track marks on arms or legs (or long sleeves in warm weather to hide marks)

  Track marks are a clear sign of intravenous drug use. They range from small red marks to open sores and bruising.

• Burns or soot on fingers or lips
• Red, flushed cheeks or face

• Can't focus on your eyes
• Red eyes
