| Stressors | are events, situations, or conditions that cause stress—they trigger a physical or emotional response in your body and mind. | |
| Abstinence | Completely avoiding a substance, like alcohol or drugs, to prevent use. | |
| Alcohol poisoning | dangerous, potentially fatal condition caused by consuming a large amount of alcohol in a short period, leading to slowed breathing, unconsciousness, or death. | |
| Anxiolytics | Medications that reduce anxiety, often prescribed for panic disorders or generalized anxiety. | |
| Behavioral undercontrol | A personality trait characterized by impulsivity, risk-taking, and poor self-regulation, increasing likelihood of substance misuse. | |
| Binge drinking | Consuming a large quantity of alcohol in a short time, typically 5+ drinks for men or 4+ drinks for women in about 2 hours. | |
| Controlled drinking | A harm-reduction approach where individuals aim to limit alcohol use rather than complete abstinence. | |
| Heavy drinking | Regularly consuming large amounts of alcohol that exceeds recommended limits (e.g., more than 14 drinks/week for men, 7 for women). | |
| Intoxication | A state of impaired physical and mental functioning caused by consuming alcohol or drugs. | |
| Delirium tremens (DTs) | Severe alcohol withdrawal symptoms including confusion, tremors, hallucinations, and seizures; can be life-threatening. | |
| Detoxification (Detox) | The medically supervised process of clearing a substance from the body and managing withdrawal symptoms. | |
| Depressant | A substance that slows down the central nervous system, reducing alertness and inhibitions (e.g., alcohol, benzodiazepines). | |
| Dissociative anesthetic | Drugs that cause a sense of detachment from the environment and self; can act as hallucinogens or sedatives (e.g., PCP, ketamine). | |
| Gateway drug | A substance whose use may lead to experimentation with more dangerous or addictive drugs (e.g., tobacco, alcohol, or marijuana). | |
| Hallucinogen | Drugs that cause perceptual distortions or hallucinations, affecting senses, mood, and thought (e.g., LSD, psilocybin). | |
| Hypnotics | Medications that induce sleep or sedation, often used for insomnia (e.g., zolpidem). | |
| Opioid | Drugs derived from opium or synthetic versions that relieve pain but can be highly addictive (e.g., morphine, heroin). | |
| Sedatives | Substances that calm or relax the central nervous system; overlap with depressants (e.g., barbiturates). | |
| Stimulant | Drugs that increase alertness, energy, or attention by stimulating the central nervous system (e.g., caffeine, cocaine, amphetamines). | |
| Motivational interviewing / Motivational enhancement therapy | Counseling approaches that help individuals resolve ambivalence and increase motivation to change substance use behaviors. | |
| Physiological dependence | When the body adapts to a substance, causing withdrawal symptoms if use stops abruptly. | |
| Psychoactive substance | Any chemical that affects mood, perception, or behavior (e.g., alcohol, nicotine, cannabis). | |
| Relapse | Returning to substance use after a period of abstinence or reduced use. | |
| Synergistic effect | When two substances combined produce effects greater than the sum of each drug alone (e.g., alcohol + sedatives). | |
| Tolerance | Needing increasing amounts of a substance to achieve the same effect due to repeated use. | |
| Withdrawal | Physical and psychological symptoms that occur when a person stops or reduces use of a substance they are dependent on (e.g., sweating, anxiety, nausea). | |
