Addiction

What is addiction?

Addiction is the regular use of a substance due to physical or psychological need. It is also known as a substance use disorder.There are many forms of addiction, and some substances are more addictive and harmful than others. The likelihood of a person becoming addicted to a substance depends on mental, physical and other health factors.

Signs of addiction can be:

Regular or continued substance use to cope emotionally, socially or physically
Neglecting responsibilities and activities that are important or enjoyable
Participating in dangerous or risky behaviours as a result of substance use
Relationship problems (e.g. arguments with partner, family, friends, or losing friends)
Physical tolerance – needing more of the substance to experience the same effects
Withdrawal – physical and mental withdrawal symptoms when you are not using the substance or needing the substance to feel “normal”
Losing control of your substance use – being dependent or unable to stop even if you want or try to
Substance use takes over your life (e.g. spending a lot of time using, finding or getting the substance and recovering from the effects).

Causes and treatment

There are many biological, social and psychological reasons why someone becomes addicted. Addiction occurs when a cycle begins in the brain. The brain encounters a substance (could be an illicit drug or alcohol or nicotine) that triggers release of the chemical dopamine, causing a feeling of relief or happiness. When this occurs repeatedly, the brain adapts, so that it feels starved of dopamine until it receives the substance that causes its release. A person then feels that they need that substance in order to feel normal or happy. Treatment is often provided through multiple services. Counselling is usually required for long term behaviour change, and to help address any underlying issues the person may have. There are also medications available to assist with recovery and withdrawal symptoms from addiction, and to reduce craving.

The best person to talk to about addiction is a GP or health care provider, who can then make a referral to the most appropriate service.

How the Florey is making a difference

Our addiction group researches how drugs, including alcohol, change the brain's structure, chemistry and function. Genetic and pharmacological approaches combined with models of drug-seeking and relapse can help uncover neural pathways implicated in drug seeking behaviour, a critical requirement in developing future treatments.
