Substance use disorder Description, Types, Causes, Symptoms, & Treatment

Delayed maturation of prefrontal‐limbic connectivity and smaller prefrontal cortex volumes can be consequences of adverse social environments during early childhood88. Substance use disorder, recurrent use of drugs or alcohol that impairs psychological and physical function and undermines the affected individual’s ability to perform day-to-day activities and fulfill personal, family, or work responsibilities. Substance use disorders typically affect adolescents and adults and range from mild to severe, the more severe cases ultimately leading to addiction. Alcohol and tobacco use disorders are among the most common types of substance use disorders worldwide. However, most prisoners with SUDs do not receive treatment during their incarceration and, when released from correctional settings, they face numerous challenges in connecting with community‐based treatment, social services, housing, and other essential supports356. This makes community re‐entry a high‐risk period for substance use relapse and also for overdosing.

Clinicians can help these individuals by recognizing their unique risk factors and health needs, including their fear of discrimination leading them to delay care341. The fundamentals of psychopharmacological and psychosocial SUD treatments are the same for patients from sexual and gender minorities as for other patients. Nevertheless, consultation with or supervision by colleagues with greater experience in treating these individuals may help clinicians whose knowledge of this population is limited. Most prevention efforts have been targeted at childhood and adolescence274, because these are periods characterized by major behavioral changes and, for adolescence, increased exposure to psychoactive substances and peer pressure275, 276. However, risks are also present during other life stages, and there is a need to develop preventive interventions for additional age groups146. Substance use and SUDs are multidetermined, with the different risk factors playing varying roles at different life stages, from the prenatal period and childhood to early and late adulthood78, 79, 164.

The United Kingdom market is leveraging AI and advanced analytics to enhance market agility, service innovation, and operational efficiency. Adoption is particularly strong in data-driven decision-making, automation of business processes, and digital platforms. Regulatory clarity around AI ethics and data protection is influencing technology strategies. Investment in AI talent, fintech-driven innovation, and cloud integration is supporting competitive differentiation.

Getting to NIMH

• Wide distribution and access to naloxone in the community is one of the most effective interventions to prevent overdose deaths263.
• In addition to existing research gaps, a common barrier is the lack of dedicated funds for preventive interventions outside research settings.
• Pedophilia can be treated with long-term individual or group psychotherapy and medications that reduce testosterone levels and thus reduce the sex drive.
• AI, analytics, and digital platforms are increasingly influencing market scalability and efficiency.
• Accurate diagnosis is key for treating co-occurring substance use and mental disorders, since symptoms may overlap.
• As part of the Helping to End Addiction Long-term® Initiative (NIH HEAL Initiative®), NIMH leads a research program that seeks to optimize the delivery of services for people with opioid use disorders, mental disorders, and suicide risk.

Attachment theory posits that the quality of the parents’ attachment system that developed in infancy will affect their ability to form healthy attachments to their own children and with other adults. Relationships serve as the communication conduits that connect family members to each other. Attachment theory provides a way of understanding the development and quality of relationships between family members. John Bowlby (1988) developed attachment theory through the clinical study of mammalian species and humans.

A first step in preventing opioid use disorder is limiting the use of opioids in patients not already receiving them, unless there are no alternatives for pain management298. However, it is important to recognize that non‐opioid analgesics often yield small to moderate short‐term effects on chronic pain299, while non‐pharmacological treatments for chronic pain are time‐consuming and costly. Cannabinoids can provide some relief of neuropathic and cancer‐related pain, but their effects are small and tend to diminish over time, and they can substance use disorder have significant side effects300.

• Medications are the most effective interventions for preventing overdose mortality and improving outcomes in patients with opioid use disorder187.
• Multiple behavioral therapies have been shown to be beneficial in the treatment of SUDs, by themselves or as adjuncts to pharmacotherapy.
• Similarly, women who smoke have a greater risk than men of tobacco‐related heart disease, lung disease, and other health problems335.
• Once the experience from drug reward has been turned into a conditioned memory, the cues by themselves drive the desire for the drug and energize the dopamine motivational circuit that propels the behaviors to pursue it33.
• Brain development during childhood and adolescence undergoes broader changes than during adulthood.

Estimates for nicotine use disorder in 2019 were 1.1 billion and included most of the active daily smokers (36.7% of all men and 7.8% of the world’s women)28. Alcohol misuse—which includes binge drinking and heavy alcohol use—over time increases the risk of alcohol use disorder (AUD). Simultaneously, early experimentation with quantum computing is beginning to influence the development of predictive analytics and personalized treatment algorithms. Although still in nascent stages, quantum’s potential to process complex datasets rapidly offers promising avenues for identifying at-risk populations and tailoring interventions with unprecedented precision. This convergence of macroeconomic shifts—such as increasing healthcare costs and the need for cost-efficient solutions—and technological innovation underscores a strategic pivot toward leveraging cutting-edge computing paradigms in SUD treatment. Moreover, the proliferation of Internet of Things (IoT) devices across healthcare and wellness sectors is fostering continuous patient monitoring, enabling real-time data collection that informs adaptive treatment plans and improves outcomes.

Behavioral interventions

The dopamine reinforcement system is dynamic, and its responses to rewards, including drugs, change as a function of the magnitude and duration of the stimulus. The first exposure to a reward (natural or drug) triggers a robust firing of dopamine neurons (phasic firing) that results in steep dopamine increases in the nucleus accumbens at levels that will bind to both D1 and D2 receptors. However, repeated exposure transforms the reward into an “expected reward”, at which point dopamine neurons fire in response to stimuli that predict the delivery of the originally rewarding stimulus45. However, if a reward is expected but is not delivered, then dopamine neuronal firing is inhibited, signaling a “reward prediction error”46.

In a healthy family, boundaries surround the parental subsystem and the child subsystem by keeping them separate. In a family with a parent who has a SUD, boundaries around the parental and child subsystems are typically permeable as the parental subsystem does not function well as a cohesive unit. Boundaries around the family itself are rigid to maintain the family secret of substance abuse. Healthy boundaries are important in the normal development of a family and children.
