Addiction, dependence, and problematic use: understanding the differences
Partager
What is an addiction?
An addiction is characterized by a persistent difficulty in controlling the use of a substance or behavior, despite negative consequences on health, family, social, school, or professional life.
The intense desire to consume, called craving, repeated unsuccessful attempts to reduce use, the increasing role of the substance in daily life, and continued use despite harm are important signs.
What is physical dependence?
Physical dependence corresponds to the body's adaptation during repeated exposure. It can manifest as tolerance — needing to increase the dose to achieve the same effect — or withdrawal symptoms upon stopping.
What is meant by "use disorder"?
Modern medical classifications describe a continuum ranging from mild to severe disorder. The assessment is not based on a single criterion but on the overall behaviors, loss of control, and consequences observed over a given period.
This approach avoids classifying people into two rigid categories — "addicts" or "non-addicts" — and allows care adapted to the degree of difficulty.
What signs may indicate problematic use?
- using more or for longer than intended;
- failing to reduce use despite several attempts;
- frequently thinking about the substance or behavior;
- neglecting important obligations or activities;
- continuing despite health, relationship, financial, or work problems;
- taking risks to obtain or use the substance;
- experiencing tolerance or withdrawal syndrome.
The presence of a single sign is not enough to make a diagnosis. This is the role of a trained professional after a comprehensive interview.
Do addictions only concern drugs?
No. Substance addictions can involve alcohol, tobacco, cannabis, opioids, cocaine, certain medications, and other psychoactive products.
Among recognized or studied behavioral addictions, gambling and certain uses of video games hold a special place. However, it is important to avoid labeling any intense habit as an "addiction" without loss of control or significant consequences.
Where to seek help?
The primary care physician can perform an initial assessment and provide guidance. CSAPAs offer free and confidential medical, psychological, and social support. Youth consumer consultations are intended for adolescents, young adults, and their families.
Asking for help does not require having "hit rock bottom." Early intervention often facilitates risk reduction and change.
