Disease category
Cannabis dependence is a category of disorders associated with cannabis use, also referred to as marijuana dependence.
Key mechanism
The use of cannabis products containing THC is a key related factor, and the impact may vary depending on the amount, frequency, THC concentration of the product, and method of use.
Main causes · Related factors
THC, a major component of cannabis, acts on the brain to alter mood and thought, while CBD generally does not produce intoxication.
Representative patterns
Representative acute manifestations may include changes in sensory and time perception and mood, difficulties with thought, memory, and problem-solving, impaired motor control, increased appetite, and slowed reaction time.
Individual differences
The risk of dependence may increase with daily use, starting use during adolescence, or using products with high THC concentrations; individual age, sex, experience, comorbidities, and other drug use can also contribute to differences.
Diagnosis
Withdrawal symptoms such as irritability, sleep difficulties, decreased appetite, anxiety, and cravings may occur upon cessation, and long-term excessive use may be associated with respiratory problems or recurrent nausea, vomiting, and abdominal pain.
Management
Diagnosis is determined by clinically synthesizing usage patterns, loss of control, continued use, cravings, withdrawal, and impairment of daily functioning, and is not confirmed by a single test alone.
Treatment/Research Status
Symptoms and risks vary depending on amount, frequency, THC concentration, route of administration, co-used drugs, and health status; therefore, cannabis use itself should not be used to conclude dependence or severity.
Read Evidence
Management is conducted by identifying goals to reduce or cease use, assessing withdrawal and accompanying mental health or substance use issues, and providing continuous support, including counseling and relapse prevention.
Key Precautions
Treatment for cannabis dependence focuses on individual assessment and psychosocial approaches, and MedlinePlus materials alone cannot be used to conclude the standard treatment or approval status of specific drugs.

At a Glance

Cannabis dependence is a category of disorders associated with cannabis use, also referred to as marijuana dependence.

Representative acute manifestations may include changes in sensory and time perception and mood, difficulties with thought, memory, and problem-solving, impaired motor control, increased appetite, and slowed reaction time.

How the disease works

The use of cannabis products containing THC is a key related factor, and the impact may vary depending on the amount, frequency, THC concentration of the product, and method of use.

THC, a major component of cannabis, acts on the brain to alter mood and thought, while CBD generally does not produce intoxication.

Variations in presentation among individuals

The risk of dependence may increase with daily use, starting use during adolescence, or using products with high THC concentrations; individual age, sex, experience, comorbidities, and other drug use can also contribute to differences.

The broad framework of diagnosis and management

Withdrawal symptoms such as irritability, sleep difficulties, decreased appetite, anxiety, and cravings may occur upon cessation, and long-term excessive use may be associated with respiratory problems or recurrent nausea, vomiting, and abdominal pain.

Diagnosis is determined by clinically synthesizing usage patterns, loss of control, continued use, cravings, withdrawal, and impairment of daily functioning, and is not confirmed by a single test alone.

Current status of treatment

Symptoms and risks vary depending on amount, frequency, THC concentration, route of administration, co-used drugs, and health status; therefore, cannabis use itself should not be used to conclude dependence or severity.

Management is conducted by identifying goals to reduce or cease use, assessing withdrawal and accompanying mental health or substance use issues, and providing continuous support, including counseling and relapse prevention.

Treatment for cannabis dependence focuses on individual assessment and psychosocial approaches, and MedlinePlus materials alone cannot be used to conclude the standard treatment or approval status of specific drugs.

How to read clinical trials

Clinical trial registration only indicates that a study has been planned and does not demonstrate efficacy, safety, approval, or standard treatment; therefore, results and study designs must be verified separately.

Points to verify during clinical consultations

In clinical practice, it is important to assess frequency and amount of use, product THC concentration and route of administration, time since last use, withdrawal/craving, changes in sleep/mood/cognition, potential for other drug use, and pregnancy possibility.
