Cannabis Use Disorder

Overview of Cannabis Use Disorder:

In Cannabis use disorder, Cannabis is derived from the hemp plant, Cannabis sativa, which has several varieties named after the region in which it is found (e.g. sativa indica in India and Pakistan, and americana in America).
Street names: Grass, Hash or Hashish, Marijuana.

Cannabis produces more than 400 identifiable chemicals of which about 50 are cannabinoids, the most active being Δ-9- tetrahydrocannabinol (Δ9THC). The pistillate form of the female plant is more important in cannabis production.

Recently, a Gi-protein (in other words, inhibitory G-protein) linked cannabinoid receptor has found (especially, in basal ganglia, hippocampus and cerebellum) which inhibits the adenylate cyclase activity in a dose-dependent manner.

Cannabis produces a very mild physical dependence, with a relatively mild withdrawal syndrome, i.e.

• Fine tremors
• Irritability
• Restlessness
• Nervousness
• Insomnia
• Decreased appetite also craving

In detail, this syndrome begins within few hours of stopping cannabis use also lasts for 4 to 5 days. However, some health professionals feel that there is no true physical dependence with cannabis.

On the other hand, psychological dependence ranges from mild (in other words, occasional ‘trips’) to marked (e.g. compulsive use). Furthermore, All the active ingredients called as marijuana or marihuana.

It can detected in urine for up to 3 weeks after chronic heavy use.

Causes of Cannabis Use Disorder

There are many causes of  this Disorder:

• The leading cause of this disorder is using marijuana for longer periods of time.
• Using larger amounts of cannabis over time.
• History of cannabis abuse among family members or friends.
• Lack of support during times of stress.
• Genetic factors can be responsible since there is some research that shows the risk of substance abuse increases with genetics.(4)

Risk factors of Cannabis Use Disorder

• Certain factors are considered to heighten the risk of developing cannabis dependence and longitudinal studies over a number of years have enabled researchers to track aspects of social and psychological development concurrently with cannabis use.
• Increasing evidence is being shown for the elevation of associated problems by the frequency and age at which cannabis is used, with young and frequent users being at most risk.
• The main factors in Australia, for example, related to a heightened risk for developing problems with cannabis use include frequent use at a young age; personal maladjustment; emotional distress; poor parenting; school drop-out; affiliation with drug-using peers; moving away from home at an early age; daily cigarette smoking; and ready access to cannabis.
• The researchers concluded there is emerging evidence that positive experiences to early cannabis use are a significant predictor of late dependence and that genetic predisposition plays a role in the development of problematic use.(2)

Types of Cannabis Use Disorder

There are three types of cannabis use disorder:

• Mild (2 or 3 criteria)
• Moderate (4 or 5 criteria)
• Severe (6 or more criteria)

The list of the criteria used is:

Unsafe use, social problems, avoidance of major responsibilities, withdrawal of the drug, tolerance level to drug use, usage of large amounts of the drug, usage for long periods of time, effort to quit using, reserving more time for use, physical or mental health problems due to using the drug or dependence, giving up activities, and cravings. (4)

Pathophysiology of Cannabis Use Disorder

• Prolonged and heavy cannabis use can alter brain circuitry. However, the specific pathophysiological mechanisms are yet unclear.
• In terms of addiction, tetrahydrocannabinol (THC) is the primary molecule responsible for the reinforcing properties of marijuana.
• Interestingly, despite the striatal dopamine system typically being involved with substances of abuse such as alcohol and opioids, meta-analysis reveals insufficient evidence at this time to support such a conclusion for cannabis. And also that dopamine receptors may not be involved.
• At a symptomatic level, heavy use modifies conscious experience by altering the brain’s network for self-awareness. By reducing anxiety and impairing memory, it also affects motivation and personal experience. At a molecular level, the story is more complex.
• The botanical provides over 500 different active chemical compounds, which interact with numerous molecular targets, thereby modulating the transmission of endocannabinoids, gamma-aminobutyric acid, glutamate, and serotonin.
• Psychoactive effects are primarily derived from tetrahydrocannabinol (THC) which binds cannabinoid receptors (CB)1 and CB2.CB1 receptors are located throughout the central nervous system (CNS), lungs, liver, and kidneys. CB2 receptors predominate within the immune hematopoietic cells.
• Binding these receptors modulates G-protein-coupled inhibition of cyclic adenosine monophosphate, thereby influencing pain, mood, appetite, nausea, and sexual activity.
• CNS effects also appear to be mediated by glial cells, particularly microglia and astrocytes. In vitro studies show microglial to produce greater endocannabinoids than neurons, and astrocytes may play a role in signaling by regulating endocannabinoid turnover.
• Thus an influence of the neuropil, not just the neurons, may better describe the CNS changes mediated by cannabis. (3)

Diagnosis of  Cannabis Use Disorder

An accurate self-diagnosis is not possible. A diagnosis must be determined by a mental health or health care professional.

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM), the criteria is:

• Persistent or recent use of cannabis (marijuana)
• Changes in  behavior which are clinically significant, and are developed after using the drug
• Development of following two or more signs within two hours of cannabis use. Irritation of conjunctiva of the eye, increased appetite,  dryness of the mouth, increased heart rate (tachycardia) (4)

Differential diagnosis of  Cannabis Use Disorder

•  Intoxication syndromes
• Amphetamine or cocaine intoxication
• Endogenous psychiatric disorders
• Generalized anxiety disorder
• Schizophrenia spectrum disorder

Complications of cannabis use disorders

1. Transient or short-lasting psychiatric disorders e.g.:

Acute anxiety, overly suspicious psychosis, vehement fugue-like states, suicidal ideation, hypomania, schizophrenia-like state (e.g. persecutory delusions, hallucinations and at times catatonic symptoms), acute organic psychosis and, very rarely, depression.

2. A motivational syndrome e.g.:

Chronic cannabis use is postulated to cause lethargy, apathy, loss of interest, anergia, reduced drive and lack of ambition. Additionally, The aetiological role of cannabis in this disorder is however far from proven.

3. ‘Hemp insanity’ or cannabis psychosis i.e.:

It was described as being similar to an acute schizophreniform disorder with disorientation and confusion, and with a good prognosis. Furthermore, The validity of this specific disorder is currently doubted.

4. Other complications i.e.:

Chronic cannabis use sometimes leads to memory impairment, either worsening or relapse in schizophrenia or mood disorder, chronic obstructive airway disease, pulmonary malignancies, alteration in both the humoral also cell-mediated immunity, decreased testosterone levels, anovulatory cycles, reversible inhibition of spermatogenesis, blockade of gonadotropin releasing hormone, also increased risk for the developing foetus (if taken during pregnancy).

Other factors like mental, emotional and physical stress that could predispose a person to illness also looked for. Now a days, even modern medicine also considers a large number of diseases as psychosomatic. The correct homeopathy remedy tries to correct this disease predisposition.

The focus is not on curing the disease but to cure the person who is sick, to restore the health. If a disease pathology not very advanced, homeopathy remedies do give a hope for cure but even in incurable cases, the quality of life can greatly improve with homeopathic medicines.
