A mental and sometimes physical state resulting from taking a drug, characterized by a compulsion to take a drug on a continuous or periodic basis. Tolerance may or may not be present, and a person may be dependent on more than one drug. Dependence on a substance is defined by explicit diagnostic criteria, such as those listed in DSM-IV. Serious and persistent involvement in the heavy use of the substance is the rule. These approaches set aside the older distinction between physical dependence and psychological dependence, which are now viewed as differing manifestations of similar disorders. The terms "alcoholism" and "addiction" are usually used as synonyms for dependence on alcohol and other drugs, respectively.
being abnormally tolerant to and dependent on something that is psychologically or physically habit-forming (especially alcohol or narcotic drugs)
A persistent and compulsive need or addiction.
A chronic, relapsing disease characterized by compulsive drug-seeking and use and by neurochemical and molecular changes in the brain. "Dependence" is sometimes used synonymously with "addiction;" a psychiatric diagnosis described in the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (1994).
Can be physical or psychological, or both. When a person's body has adapted to a drug and is used to functioning with the drug present, the person is said to be physically dependent upon that drug. When a person feels compelled to use a drug in order to function effectively or to achieve emotional satisfaction, the person is said to be psychologically dependent upon that drug
the drug has become central to a person’s thoughts, emotions and activities. Stopping, or reducing the drug suddenly, can lead to physical withdrawal symptoms.
Dependence refers to when a person is reliant on a substance or person to help them function on a day-to-day level. It can also be used to refer to a person who has become reliant on a medication to function in society.
Particular behavioural, cognitive and physiological effects that may arise through repeated substance use. Psychological characteristics of dependence include a strong desire to take the drug, impaired control over use, persistent use despite harmful consequences, and the prioritisation of drug use over other activities (NCETA, 2002).
A state in which one cannot readily give up or stop the use of a drug. There are two types of dependence – physical and psychological. Physical dependence is the physical need of the body for a particular substance such that abstinence from the substance leads to physical withdrawal symptoms. Psychological dependence is an emotional reliance on a particular substance or a strong and continued craving.
A psychological compulsion to use a drug that is not linked to physical addiction.
The body goes through a withdrawal period once a medication is ceased.
a state in which a person is reliant on a drug. Physical dependence is characterized by the onset of physical symptoms of withdrawal (e.g., sweating, tremors) if a drug is abruptly stopped. Psychological dependence (addiction) is a psychological syndrome characterized by drug craving, compulsive use and relapse after abstinence.
State where the user continues its use of the substance despite significant health, psychological, relational, familial or social problems. Dependence is a complex phenomenon which may have genetic components. Psychological dependence refers to the psychological symptoms associated with craving and physical dependence to tolerance and the adaptation of the organism to chronic use. The American Psychiatric Association has proposed seven criteria (see chapter 7).
Physical dependence is when someone has taken drugs in quantity for a time and comes to rely on the use of a drug in order to feel well and for their body to function 'normally'. It usually happens when the body has built up a tolerance to the drug and in its absence, physical withdrawal symptoms appear. Psychological dependence is when the user experiences an overwhelming desire to continue with the drug experience. This can be because of the pleasurable effects and the desire to keep experiencing them.
See "physical dependence."
The need for a drug, resulting from continuous use, characterized by physical or mental withdrawal in the absence of the drug.
Physiological and/or psychological reliance on or addiction to a substance, which results from the recurrent use of the substance; characterized by mental and/or physical changes in the user that make it difficult to stop usage.
Use in three different ways: (1) physical dependence, a physiological state of adaptation to a specific psychoactive substance characterized by the emergence of a withdrawal syndrome during abstinence, which may be relieved in total or in part by readministration of the substance; (2) psychological dependence, a subjective sense of need for a specific psychoactive substance, either for its positive effects or to avoid negative effects associated with its abstinence; and (3) one category of psychoactive substance use disorder.
craving or physical need for a drug which interferes with physical and mental health, social responsibility and well-being.
(physical or psychological): As a general term, the state of needing or depending on something or someone for support or to function or survive. As applied to alcohol and other drugs, the term implies a need for repeated doses of the drug to feel good or to avoid feeling bad. In the Diagnostic and Statistical Manual of Mental Disorders, or DSM-IV, dependence is defined as "a cluster of cognitive, behavioral and, physiologic symptoms that indicate a person has impaired control of psychoactive substance use and continues use of the substance despite adverse consequences." Being compelled to keep using a drug - even when you realize that you have a physical or psychological problem that is probably caused or made worse by the drug.
A psychic craving for a drug or other substance which may or may not be accompanied by a physical dependency Reliance on a drug or other substance to maintain health PS addiction
The physiological state of neuroadaptation produced by repeated administration of a drug, necessitating continued administration to prevent the appearance of the withdrawal syndrome.
a condition marked by use of a substance in excessive dosages or for a longer period than directed by a physician; use despite persistent social, psychological, and physical problems; expenditure of considerable effort to obtain,use, and recover from a sub-stance; withdrawal symptoms or repeated failure to reduce or control use; and continued use to relieve or avoid withdrawal symptoms.
This term is often used to mean the same thing as addiction. It can be thought of in two ways: (1) psychological feelings of discomfort when the drug is not available (psychological dependence), or (2) a state where the body requires the regular use of alcohol or other drugs in order to continue to function (physical dependence). If a person develops physical dependence and then stops taking the drug, he/she is likely to experience withdrawal symptoms.
Dependence is a compulsion to continue taking a drug in order to feel good or to avoid feeling bad.
