Based on representative samples of the US youth population in 2011update, the lifetime prevalencenote 7 of addictions to alcohol and illicit drugs has been estimated to be approximately 8% and 2–3% respectively. Physical dependence occurs when the body has adjusted by incorporating the substance into its “normal” functioning – i.e., attains homeostasis – and therefore physical withdrawal symptoms occur on cessation of use. CREB transcription in the nucleus accumbens is implicated in psychological dependence and symptoms involving a lack of pleasure or motivation during drug withdrawal. Nearly all addictive drugs, directly or indirectly, act on the brain’s reward system by heightening dopaminergic activity. A recent study in Addiction reports that GLP-1 agonist medications, such as semaglutide, which are commonly used for diabetes and weight management, may also reduce the risk of overdose and alcohol intoxication in people with substance use disorders.
Distinction between psychological and physical dependence
Artists attempt to change the societal perception of addiction from a punishable moral offense to instead a chronic illness necessitating treatment. It can influence healthcare policy, making it difficult for these individuals to access treatment. The KFD can be used in family sessions to allow children to share their experiences and needs with parents who may be in recovery from alcohol use disorder. Formal assessments such as FEATS provide healthcare providers with a means to quantify, standardize, and communicate abstract and visceral characteristics of SUDs to provide more accurate diagnoses and informed treatment decisions. Music therapy was identified to have potentially strong beneficial effects in aiding contemplation and preparing those diagnosed with substance use for treatment.
Environmental factors
Children’s neurological development can be permanently disrupted when they are chronically exposed to stressful events such as physical, emotional, or sexual abuse, physical or emotional neglect, witnessing violence in the household, or a parent being incarcerated or having a mental illness. In this case, the addictive substance provides brief but total relief and positive feelings of control. The psychoanalytic theory model defines addiction as a form of defense against feelings of hopelessness and helplessness as well as a symptom of failure to regulate powerful emotions related to adverse childhood experiences (ACEs), various forms of maltreatment and dysfunction experienced in childhood.

Therapy typically involves the use of cognitive-behavioral therapy, an approach that looks at the relationship between thoughts, feelings and behaviors, addressing the root cause of maladaptive behavior. Opiate replacement therapy has been a medical standard of treatment for opioid addiction for many years. As a chronic, relapsing disease, addiction may require continued treatments to increase the intervals between relapses and diminish their intensity.
Charity Action on Addiction, 1 in 3 people in the world have an addiction of some kind. That’s why it’s important for anyone who is experiencing addiction to seek help. They can lead to permanent health complications and serious consequences like bankruptcy. People experiencing addiction are also prone to cycles of relapse and remission. Relapse is viewed as an opportunity for learning and strategy adjustment, with the ultimate goal of eliminating or terminating the targeted behavior. Contemplation is the stage in which individuals become aware of the problems caused by their addiction and are considering change.
- Upregulation of CREB expression in the nucleus accumbens plays a major role in mediating psychological dependence by inhibiting reward-related motivational salience, which mediates the onset of emotional-motivational withdrawal symptoms.
- In addition, new research surrounding the effects of psilocybin on smokers revealed that 80% of smokers quit for six months following the treatment, and 60% remained smoking free for 5 years following the treatment.
- Someone with an addition won’t stop their behavior, even if they recognize the problems the addiction is causing.
- Physical dependence on opioids has been observed to produce an elevation of extracellular glutamate, an increase in NMDA receptor subunits NR1 and NR2A, phosphorylated CaMKII, and c-fos.
Symptoms
Illicit drug use has been found to cause epigenetic changes in DNA methylation, as well as chromatin remodeling. During this period, limbic reward circuits mature earlier than prefrontal cortex regulatory networks, creating a developmental imbalance in which reward sensitivity is high, but cognitive control is not fully developed yet. In 2011, there were approximately 20.6 million people in the United States over the age of 12 with an addiction. This pathway towards addiction that is opened through stressful experiences during childhood can be avoided by a change in environmental factors throughout an individual’s life and opportunities of professional help.
Reward system
Research on the interaction between natural and drug rewards suggests that dopaminergic psychostimulants (e.g., amphetamine) and sexual behavior act on similar biomolecular mechanisms to induce ΔFosB in the nucleus accumbens and possess bidirectional cross-sensitization effects that are mediated through ΔFosB. ΔFosB plays an important role in regulating behavioral responses to natural rewards, such as palatable food, sex, and exercise. With respect to addiction, more research is needed to determine the specific heritable epigenetic alterations that arise from various forms of addiction in humans and the corresponding behavioral phenotypes from these epigenetic alterations that occur in human offspring. Ths can produce long term alterations in executive functioning and reward processing that increase the chance of developing a substance use disorder. This mismatch contributes to higher experimentation with substances and vulnerability to addiction.
A common use of the term addiction in medicine is for neuropsychological symptoms denoting pervasive/excessive and intense urges to engage in a category of behavioral compulsions or impulses towards sensory rewards (e.g., alcohol, betel quid, drugs, sex, gambling, video gaming). ΔFosB inhibitors (drugs or treatments that oppose its action) may be an effective treatment for addiction and addictive disorders. Other behaviors that can produce observable psychological withdrawal symptoms (i.e., cause psychological dependence) include shopping, sex and self-stimulation using pornography, and eating food with high sugar or fat content, among others. Consistent and frequent exposure to particular substances or behaviors is responsible for inducing psychological dependence, requiring ongoing engagement to prevent the onset of brain changes associated with long-term ketamine abuse, a systematic review pmc an unpleasant withdrawal syndrome driven by negative reinforcement. Psychological dependence is a cognitive disorder and a form of dependence that is characterized by emotional–motivational withdrawal symptoms upon cessation of prolonged drug use or certain repetitive behaviors.
- Based on representative samples of the US adult population in 2011update, the 12-month prevalence of alcohol and illicit drug addictions were estimated at 12% and 2–3% respectively.
- Substance-abuse rehabilitation (rehab) centers offer a residential treatment program for some of the more seriously addicted, in order to isolate the patient from drugs and interactions with other users and dealers.
- They can lead to permanent health complications and serious consequences like bankruptcy.
- While regarded biomedically as a neuropsychological disorder, addiction is multi-layered, with biological, psychological, social, cultural, and spiritual (biopsychosocial–cultural–spiritual) elements.
Genetic factors
Alcohol abuse or dependence reported a lifetime prevalence of 18.1% and a 12-month prevalence of 3.2%. An article in The Washington Post stated that “America’s largest drug companies flooded the country with pain pills from 2006 through 2012, even when it became apparent that they were fueling addiction and overdoses.” According to a 2017 poll conducted by the Pew Research Center, almost half of US adults know a family member or close friend who has struggled with a drug addiction at some point in their life. The time-invariant prevalence rate for sexual addiction and related compulsive sexual behavior (e.g., compulsive masturbation with or without pornography, compulsive cybersex, etc.) within the US ranges from 3–6% of the population.

It is unclear whether laws against illegal drug use do anything to stem usage and dependency. Furthermore, dependence rates were greater in unemployed populations ages 18 and older and in metropolitan-residing populations ages 12 and older. However, when it came to illicit drug use there was a correlation, in which those that graduated from college had the lowest rates.
The phenomenon of drug addiction has occurred to some degree throughout recorded history (see Opium). Group therapies including anonymity, teamwork and sharing concerns of daily life among people who also have substance dependence issues can have a great impact on outcomes. Biological intervention should be combined with behavioral therapy approaches and other non-pharmacological techniques. Similarly, one can also substitute the misused substance with a weaker, safer version to slowly taper the patient off of their dependence. Cognitive treatment requires psychologists to think deeply about what is happening in the brain of an addicted person.
Internationally, the U.S. and Eastern Europe contain the countries with the highest substance abuse disorder occurrence (5-6%). Furthermore, as technology advanced, more drugs were synthesized and discovered, opening up new avenues to substance dependency. Another approach is to use medicines that interfere with the functions of the drugs in the brain. With the advanced clinical use of medications, biological treatment is now considered to be one of the most efficient interventions that psychologists may use as treatment for those with substance dependence. Behavioral techniques have the widest application in treating substance related disorders. Medical professionals need to apply many techniques and approaches to help patients with substance related disorders.
Finally, the arts can be used to advocate for those suffering from a substance use disorder by raising awareness of the issue and promoting understanding and compassion. Through art, individuals can gain insights into their own motivations and behaviors that can be helpful in determining a course of treatment. The arts can be used as an assessment tool to identify underlying issues that may be contributing to a person’s substance use disorder. It was not until the 19th century that addiction was seen and acknowledged in the Western world as a disease, being both a physical condition and mental illness. In Ontario, Canada between 2009 and 2017, outpatient visits for mental health and addiction increased from 52.6 to 57.2 per 100 people, emergency department visits increased from 13.5 to 19.7 per 1000 people and the number of hospitalizations increased from 4.5 to 5.5 per 1000 people. Cannabis abuse or dependence reported a lifetime prevalence of 6.8% and a 12-month prevalence of 3.2%.
Across the globe, those that tended to have a higher prevalence of substance dependence were in their twenties, unemployed, and men. Improved means of active biological agent manufacture and the introduction of synthetic compounds, such as fentanyl and methamphetamine, are also factors contributing to drug addiction. Modern agricultural practices, improvements in access to drugs, advancements in biochemistry, and dramatic increases in the recommendation of drug usage by clinical practitioners have exacerbated the problem significantly in the 20th century.
Other possible causes of addiction include chemical imbalances in the brain and mental disorders such as schizophrenia or bipolar disorder. Addictive substances and behaviors can create a pleasurable “high” that’s physical and psychological. Later, 19th century temperance movements narrowed the definition of addiction to just drug-related disease, ignoring behavioral addictions and the possibility of positive or neutral addictions. As of 2021,update 43.7 million people aged 12 or older surveyed by the National Survey on Drug Use and Health in the United States needed treatment for an addiction to alcohol, nicotine, or other drugs.
