What Is Addiction? What Causes Addiction?
People with an addiction do not have control over what they are doing, taking or using. Their addiction may reach a point at which it is harmful. Addictions do not only include physical things we consume, such as drugs or alcohol, but may include virtually anything, such abstract things as gambling to seemingly harmless products, such as chocolate – in other words, addiction may refer to a substance dependence (e.g. drug addiction) or behavioral addiction (e.g. gambling addiction).
This article focuses mainly on addiction to physical substances.
In the past addiction used to refer just to psychoactive substances that cross the blood-brain barrier, temporarily altering the chemical balance of the brain; this would include alcohol, tobacco and some drugs. A considerable number of psychologists, other health care professionals and lay people now insist that psychological dependency, as may be the case with gambling, sex, internet, work, exercise, etc. should also be counted as addictions, because they can also lead to feelings of guilt, shame, hopelessness, despair, failure, rejection, anxiety and/or humiliation.
When a person is addicted to something they cannot control how they use it, and become dependent on it to cope with daily life.
A habit may eventually develop into an addiction Many of us can use substances or become engaged in activities without any significant problems. Some people, however, may experience damaging psychological and/or physical effects when their habit becomes an addiction.
What is the difference between a habit and an addiction?
Addiction – there is a psychological/physical component; the person is unable to control the aspects of the addiction without help because of the mental or physical conditions involved.
Habit – it is done by choice. The person with the habit can choose to stop, and will subsequently stop successfully if they want to. The psychological/physical component is not an issue as it is with an addiction.
Put simply – with a habit you are in control of your choices, with an addiction you are not in control of your choices.
Addiction to substances or activities can sometimes lead to serious problems at home, work, school and socially.
The causes of addiction vary considerably, and are not often fully understood. They are generally caused by a combination of physical, mental, circumstantial and emotional factors.
Addiction, often referred to as dependency often leads to tolerance – the addicted person needs larger and more regular amounts of whatever they are addicted to in order to receive the same effect. Often, the initial reward is no longer felt, and the addiction continues because withdrawal is so unpleasant.
HOW YOUR BRAIN GETS ADDICTED TO FOOD.
A new study shows how some foods can be as addictive as drugs.
Scientists have long suspected that obese people may be “addicted” to food the same way druggies are hooked on narcotics—that is, their brains’ pleasure centers are somehow “hardwired” to make cravings start at even the suggestion of the addictive substance.
There may be some truth in it. A new study shows that, for getting the brain in an excited state, heroin and Häagen-Dazs seem to be pretty close buddies.
In the study, presented to the European College of Neuropsychopharmacology (try that one after a couple of beers), two groups—one obese, one of normal weight—were fed a buffet, then put in an MRI to track their brain activity while viewing pics of the same foods. Result: The fat folks’ reward centers lit up much more than other subjects’.
What’s more, using the study data, researchers were able to predict which subjects would gain weight before the next follow-up.
