Substance abuse, also known as drug abuse, is the use of a drug in amounts or by methods that are harmful to the individual or others. It is a form of substance-related disorder. Differing definitions of drug abuse are used in public health, medical, and criminal justice contexts. In some cases, criminal or anti-social behavior occurs when the person is under the influence of a drug, and long-term personality changes in individuals may also occur. In addition to possible physical, social, and psychological harm, the use of some drugs may also lead to criminal penalties, although these vary widely depending on the local jurisdiction.
Harm reduction, or harm minimization, refers to a range of intentional practices and public health policies designed to lessen the negative social and/or physical consequences associated with various human behaviors, both legal and illegal. Harm reduction is used to decrease negative consequences of recreational drug use and sexual activity without requiring abstinence, recognizing that those unable or unwilling to stop can still make positive change to protect themselves and others.
Drug rehabilitation is the process of medical or psychotherapeutic treatment for dependency on psychoactive substances such as alcohol, prescription drugs, and street drugs such as cannabis, cocaine, heroin, and amphetamines. The general intent is to enable the patient to confront substance dependence, if present, and stop substance misuse to avoid the psychological, legal, financial, social, and medical consequences that can be caused.
Self-medication, sometime called do-it-yourself (DIY) medicine, is a human behavior in which an individual uses a substance or any exogenous influence to self-administer treatment for physical or psychological conditions, for example headaches or fatigue.
Opioid use disorder (OUD) is a substance use disorder characterized by cravings for opioids, continued use despite physical and/or psychological deterioration, increased tolerance with use, and withdrawal symptoms after discontinuing opioids. Opioid withdrawal symptoms include nausea, muscle aches, diarrhea, trouble sleeping, agitation, and a low mood. Addiction and dependence are important components of opioid use disorder.
Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption of the drug. A drug addiction, a distinct concept from substance dependence, is defined as compulsive, out-of-control drug use, despite negative consequences. An addictive drug is a drug which is both rewarding and reinforcing. ΔFosB, a gene transcription factor, is now known to be a critical component and common factor in the development of virtually all forms of behavioral and drug addictions, but not dependence.
Sexual addiction is a state characterized by compulsive participation or engagement in sexual activity, particularly sexual intercourse, despite negative consequences. The concept is contentious; neither of the two major mainstream medical categorization systems recognise sex addiction as a real medical condition, instead categorizing such behavior under labels such as compulsive sexual behavior.
Contingency management (CM) is the application of the three-term contingency, which uses stimulus control and consequences to change behavior. CM originally derived from the science of applied behavior analysis (ABA), but it is sometimes implemented from a cognitive-behavioral therapy (CBT) framework as well.
Sex and drugs date back to ancient humans and have been interlocked throughout human history. Both legal and illegal, the consumption of drugs and their effects on the human body encompasses all aspects of sex, including desire, performance, pleasure, conception, gestation, and disease.
An addictive behavior is a behavior, or a stimulus related to a behavior, that is both rewarding and reinforcing, and is associated with the development of an addiction. There are two main forms of addiction: substance use disorders and behavioral addiction. The parallels and distinctions between behavioral addictions and other compulsive behavior disorders like bulimia nervosa and obsessive-compulsive disorder (OCD) are still being researched by behavioral scientists.
Dual diagnosis is the condition of having a mental illness and a comorbid substance use disorder. There is considerable debate surrounding the appropriateness of using a single category for a heterogeneous group of individuals with complex needs and a varied range of problems. The concept can be used broadly, for example depression and alcohol use disorder, or it can be restricted to specify severe mental illness and substance use disorder, or a person who has a milder mental illness and a drug dependency, such as panic disorder or generalized anxiety disorder and is dependent on opioids. Diagnosing a primary psychiatric illness in people who use substances is challenging as substance use disorder itself often induces psychiatric symptoms, thus making it necessary to differentiate between substance induced and pre-existing mental illness.
Behavioral addiction, process addiction, or non-substance-related disorder is a form of addiction that involves a compulsion to engage in a rewarding non-substance-related behavior – sometimes called a natural reward – despite any negative consequences to the person's physical, mental, social or financial well-being. In the brain's reward system, a gene transcription factor known as ΔFosB has been identified as a necessary common factor involved in both behavioral and drug addictions, which are associated with the same set of neural adaptations.
Polysubstance dependence refers to a type of substance use disorder in which an individual uses at least three different classes of substances indiscriminately and does not have a favorite substance that qualifies for dependence on its own. Although any combination of three substances can be used, studies have shown that alcohol is commonly used with another substance. One study on polysubstance use categorized participants who used multiple substances according to their substance of preference. The results of a longitudinal study on substance use led the researchers to observe that excessively using or relying on one substance increased the probability of excessively using or relying on another substance.
Substance use disorder (SUD) is the persistent use of drugs despite the substantial harm and adverse consequences to one's own self and others, as a result of their use. In perspective, the effects of the wrong use of substances that are capable of causing harm to the user or others, have been extensively described in different studies using a variety of terms such as substance use problems, problematic drugs or alcohol use, and substance use disorder.The National Institute of Mental Health (NIMH) states that "Substance use disorder (SUD) is a treatable mental disorder that affects a person's brain and behavior, leading to their inability to control their use of substances like legal or illegal drugs, alcohol, or medications. Symptoms can be moderate to severe, with addiction being the most severe form of SUD".Substance use disorders (SUD) are considered to be a serious mental illness that fluctuates with the age that symptoms first start appearing in an individual, the time during which it exists and the type of substance that is used. It is not uncommon for those who have SUD to also have other mental health disorders. Substance use disorders are characterized by an array of mental/emotional, physical, and behavioral problems such as chronic guilt; an inability to reduce or stop consuming the substance(s) despite repeated attempts; operating vehicles while intoxicated; and physiological withdrawal symptoms. Drug classes that are commonly involved in SUD include: alcohol (alcoholism); cannabis; opioids; stimulants such as nicotine (including tobacco), cocaine and amphetamines; benzodiazepines; barbiturates; and other substances.
Addiction is a neuropsychological disorder characterized by a persistent and intense urge to use a drug or engage in a behavior that produces natural reward, despite substantial harm and other negative consequences. Repetitive drug use often alters brain function in ways that perpetuate craving, and weakens self-control. This phenomenon – drugs reshaping brain function – has led to an understanding of addiction as a brain disorder with a complex variety of psychosocial as well as neurobiological factors that are implicated in addiction's development.
A psychoactive drug, mind-altering drug, or consciousness-altering drug is a chemical substance that changes brain function and results in alterations in perception, mood, consciousness, cognition, or behavior. The term psychotropic drug is often used interchangeably, while some sources present narrower definitions. These substances may be used medically; recreationally; to purposefully improve performance or alter one's consciousness; as entheogens for ritual, spiritual, or shamanic purposes; or for research, including psychedelic therapy. Some categories of psychoactive drugs, which have therapeutic value, are prescribed by physicians and other healthcare practitioners. Examples include anesthetics, analgesics, anticonvulsant and antiparkinsonian drugs as well as medications used to treat neuropsychiatric disorders, such as antidepressants, anxiolytics, antipsychotics, and stimulant medications. Some psychoactive substances may be used in the detoxification and rehabilitation programs for persons dependent on or addicted to other psychoactive drugs.
About 1 in 7 Americans suffer from active addiction to a particular substance. Addiction can cause physical, psychological, and emotional harm to those who are affected by it. The American Society of Addiction Medicine defines addiction as "a treatable, chronic medical disease involving complex interactions among brain circuits, genetics, the environment, and an individual's life experiences. People with addiction use substances or engage in behaviors that become compulsive and often continue despite harmful consequences." In the world of psychology and medicine, there are two models that are commonly used in understanding the psychology behind addiction itself. One model is referred to as the disease model of addiction. The disease model suggests that addiction is a diagnosable disease similar to cancer or diabetes. This model attributes addiction to a chemical imbalance in an individual's brain that could be caused by genetics or environmental factors. The second model is the choice model of addiction, which holds that addiction is a result of voluntary actions rather than some dysfunction of the brain. Through this model, addiction is viewed as a choice and is studied through components of the brain such as reward, stress, and memory. Substance addictions relate to drugs, alcohol, and smoking. Process addictions relate to non-substance-related behaviors such as gambling, spending money, sexual activity, gaming, spending time on the internet, and eating.
Discrimination against people with substance use disorders is a form of discrimination against people with this disease. In the United States, people with substance use disorders are often blamed for their disease, which is often seen as a moral failing, due to a lack of public understanding about substance use disorders being diseases of the brain with 40-60% heritability. People with substance use disorders are likely to be stigmatized, whether in society or healthcare.
Prescription drug addiction is the chronic, repeated use of a prescription drug in ways other than prescribed for, including using someone else’s prescription. A prescription drug is a pharmaceutical drug that may not be dispensed without a legal medical prescription. Drugs in this category are supervised due to their potential for misuse and substance use disorder. The classes of medications most commonly abused are opioids, central nervous system (CNS) depressants and central nervous stimulants. In particular, prescription opioid is most commonly abused in the form of prescription analgesics.
The Impact of prostitution on mental health refers to the psychological, cognitive, and emotional consequences experienced by individuals involved in prostitution. These consequences include a wide range of mental health issues and difficulties in emotional management and interpersonal relationships. Prostitution is closely linked to various psychological pathologies and affects not only those directly involved but also society at large. Studies have shown that both street and indoor sex workers have experienced high levels of abuse in childhood and adulthood, with differences in trauma rates between the two groups.
