1 of 3

• Alcohol abuse involves excessive consumption leading to physical, mental, and social problems
• Drug abuse includes misuse of illegal substances (heroin, cocaine) and prescription medications (opioids, benzodiazepines)
• Polysubstance abuse refers to the concurrent use of multiple drugs, increasing health risks and complicating treatment

Diagnostic criteria

• DSM-5 outlines specific criteria for Substance Use Disorders (SUDs), replacing older terms like "abuse" and "dependence"
• Criteria include impaired control, social impairment, risky use, and pharmacological indicators (tolerance, withdrawal)
• Severity of SUD classified as mild, moderate, or severe based on the number of criteria met
• Assessment tools like CAGE questionnaire and AUDIT used for screening and diagnosis

Difference from addiction

• Substance abuse refers to harmful use patterns, while addiction involves compulsive drug-seeking behavior despite negative consequences
• Abuse can lead to addiction, but not all substance abuse results in addiction
• Addiction characterized by changes in brain chemistry, particularly in reward and motivation systems
• Substance abuse may be situational or temporary, while addiction is typically chronic and requires long-term management

Common substances of abuse

Alcohol

• Most widely abused substance in the United States, with approximately 14.5 million people aged 12 and older having an Alcohol Use Disorder
• Depressant affecting central nervous system, leading to impaired judgment, coordination, and potential liver damage
• Binge drinking patterns common among young adults, defined as consuming 5 or more drinks for men, 4 or more for women, within 2 hours
• Long-term effects include increased risk of cancer, cardiovascular disease, and cognitive decline

Opioids

• Include prescription painkillers (oxycodone, hydrocodone) and illicit drugs (heroin, fentanyl)
• Opioid crisis declared a public health emergency in 2017, with over 70,000 overdose deaths in 2019
• Highly addictive due to their effect on the brain's reward system and rapid development of tolerance
• Medication-assisted treatment (MAT) using methadone or buprenorphine effective for managing opioid addiction

Stimulants

• Encompass both illicit drugs (cocaine, methamphetamine) and prescription medications (Adderall, Ritalin)
• Increase alertness, attention, and energy by affecting neurotransmitters like dopamine and norepinephrine
• Abuse can lead to cardiovascular problems, psychosis, and severe addiction
• Treatment often focuses on behavioral therapies, as no FDA-approved medications exist for stimulant addiction

Hallucinogens

• Include substances like LSD, psilocybin (magic mushrooms), and MDMA (ecstasy)
• Alter perception, mood, and cognitive processes, often used for recreational or spiritual purposes
• Generally have lower addiction potential compared to other drug classes

Causes of substance abuse

Genetic factors

• Heredity accounts for about 40-60% of a person's vulnerability to addiction

• Peer pressure and social norms play significant roles, especially among adolescents and young adults
• Availability and accessibility of substances in a given environment impact rates of use and abuse

Psychological factors

• Mental health disorders often co-occur with substance abuse (dual diagnosis)
• Substances may be used as self-medication for underlying mental health issues (depression, anxiety, PTSD)
• Personality traits like impulsivity and sensation-seeking associated with higher risk of substance abuse
• Trauma and stress can trigger substance use as a coping mechanism

Societal pressures

• Cultural attitudes towards substance use vary, influencing acceptance and prevalence
