Substance use disorder (SUD) is a treatable mental disorder that affects a person’s brain and behavior, leading to an inability to control the use of substances like legal or illegal drugs, alcohol, or medications. Symptoms can be moderate to severe, with addiction being the most severe form of SUD.
Internet addiction disorder (IAD) is a type of behavioral addiction that involves compulsive Internet use. People with an Internet addiction may have underlying mental health or substance use issues that may require specialized addiction treatment.
Alcohol use disorder is a pattern of alcohol use that involves problems controlling drinking, being preoccupied with alcohol or continuing to use alcohol even when it causes problems. This disorder also involves having to drink more to get the same effect or having withdrawal symptoms when use rapidly decreases or stops. Alcohol use disorder includes a level of drinking that’s sometimes called alcoholism.
Compulsive gambling, also called gambling disorder, is the uncontrollable urge to keep gambling despite the toll it takes on your life. Gambling means that you’re willing to risk something you value in the hope of getting something of even greater value.
Gambling can stimulate the brain’s reward system much like drugs or alcohol can, leading to addiction. If you have a problem with compulsive gambling, you may continually chase bets that lead to losses, use up savings and create debt. You may hide your behavior and even turn to theft or fraud to support your addiction.
