Substance Abuse and Addiction

What is Addiction?

"Addiction" or "severe substance use disorder" is a complex condition; a brain disease that is manifested by compulsive substance use despite harmful consequence. People with addiction have an intense focus on using certain substances to cope with stress or life in general.

What is Substance Addiction?

Substance dependence is the medical term used to describe abuse of drugs, alcohol, or chemicals that continues even when significant problems related to their use have developed. Signs of dependence include:

Tolerance to or need for increased amounts of the drug to get an effect

Withdrawal symptoms from stopping or decreasing the addiction

Spending a lot of time to get, use, and recover from the effects of using drugs

Withdrawal from social and recreational activities

Continued use of the drug even though you are aware of the physical, psychological, and family/social problems that are caused by your ongoing drug abuse

What is Behavioral Addiction?

Behavioral addiction occurs when someone becomes addicted to a rewarding behavior that does not involve an addictive substance. Sometimes referred to as behavioral addictions or compulsive behaviors, process addictions involve compulsion to perform an action despite negative consequences. In this way people can suffer from dependence on certain processes — they are reliant upon and/or controlled by the addiction as their primary way of dealing with life. Below are common process addictions:

Gambling

Sex

Work

Spending or compulsive buying

Internet or Gaming

Eating
