This American Prosecutors Research Institute primer explains alcohol toxicology concepts used in impaired-driving cases, including absorption, distribution, elimination, alcohol concentration estimates, and retrograde extrapolation. It also discusses limits of estimates, post-incident drinking, multiple test results, and common defenses for legal professionals interpreting toxicology evidence.
This collection examines research on alcohol and marijuana used together, including whether their combined effects relate to blackouts and other harms. The studies summarized consider college and young-adult populations, patterns of simultaneous or concurrent use, and factors such as gender, motives, and amount consumed when examining reported consequences.
This National Institute on Alcohol Abuse and Alcoholism brochure explains that alcohol can change how medicines work and that medicines can alter alcohol’s effects. It gives examples of prescription and over-the-counter drug interactions, describes possible effects such as drowsiness and impaired coordination, and includes guidance on reading medication labels and finding further information.
This May 2023 continuing-education handout reviews alcohol blackouts and their relevance to allegations of sexual offenses. It covers memory impairment, blackout types, toxicology, and legal strategies, and includes research abstracts on alcohol-related behavior, blackouts, memory for events, and estimates of drinking.
This collection reviews research on the co-occurrence of bipolar disorder and substance use, including how the combination may affect diagnosis and illness course. The studies discuss high comorbidity, possible roles for impulsivity, and limited controlled treatment evidence, with one review describing integrated medication and psychosocial approaches as promising but in need of further study.
The article reviews evidence that alcohol changes the timing and structure of sleep in healthy people. It describes faster sleep onset and more deep sleep early in the night, followed by greater disruption later, and summarizes research linking intoxication with reduced REM sleep and poorer reported sleep quality.
This collection reviews research on genetic variation in alcohol-metabolizing enzymes and alcohol-related outcomes across several populations. The studies report differing associations involving ADH and ALDH variants, including possible protective effects in particular samples, while emphasizing that these findings do not by themselves explain population-level differences in alcohol problems.
This clinical overview describes alcohol-related psychosis, which may arise during or soon after heavy drinking or during withdrawal and can involve hallucinations, paranoia, or fear. It reviews diagnostic considerations, possible causes, evaluation, and management, and emphasizes distinguishing alcohol-induced symptoms from schizophrenia, delirium, and other medical causes.
This collection reviews research on alcohol-related disinhibition and behavior, especially sexual responses, decision-making, and risk-taking. The included studies discuss social disinhibition alongside learning, expectations, and individual factors, showing that researchers have examined several possible pathways rather than treating disinhibition as a universal response to alcohol.
This article reviews how alcohol may affect memory formation and reconstruction for criminal events, including attention, episodic memory, and the encoding of new information. It also collects research on alcohol and eyewitness or suspect reporting, describing findings that vary across studies and memory tasks rather than treating intoxication as having one uniform effect.
