Most everyone has overindulged at some point in their lives, from having a bit too much to drink or smoking in a social environment to perhaps even experimenting with illegal substances. While most people who “dabble” in unhealthy habits quickly recognize the downside and can easily stop, others have a much harder time quitting.
Medically speaking, substance abuse refers to a pattern of using or misusing substances that cause significant problems or distress. This can range from missing work or school to engaging in dangerous behaviors like driving while intoxicated.
