Can Alcohol Change How Accurately Someone Counts Objects? A Visual Enumeration Study
A 40-student visual counting study found 67% vs 64% group accuracy before and after drinking. Learn what that does—and does not—show about eyewitness counts.
Does Alcohol After Practice Change Motor Memory? A 24-Person Trial
A 24-person crossover study found no meaningful change in next-day motor retention after alcohol, although some movement accuracy and speed outcomes changed.
Can Alcohol Impair Remembering to Act Later? Time-Cue Evidence and Legal Limits
Does alcohol impair remembering to act later? Examine a 52-person placebo-controlled MIST study, time-cue omissions, error rates and legal interpretation limits.
Can Gender-Affirming Hormone Therapy Change a Widmark BAC Estimate? A Body-Water Model’s Limits
Can hormone therapy alter a Widmark BAC estimate? Review measured body-water datasets, modeled BAC differences, unvalidated formulas and forensic limits.
Does a Hair THC Test Prove a Teen’s Memory Problems? The 2026 Longitudinal Evidence
Does THC detected in a teen’s hair prove memory impairment? A 2026 longitudinal ABCD study explains exposure, cognitive trajectories and limits of causation.
Does Drinking After an Incident Make a Witness Unreliable? A Controlled Study
A 60-person controlled study separates drinking after an incident from intoxication while witnessing it—and memory completeness from accuracy.
Does Oral THC Oil Change Hazard Detection, Speed Choices, and Following Distance? A 41-Driver Video Study
In 41 medicinal-cannabis users, prescribed THC oil did not significantly alter video hazard response time, but changed stated speed and following gaps. See limitations.
Does a 45-Minute Cannabis Memory Test Prove Greater Impairment in Men? What 154 Adults Showed
A 154-adult cannabis study found lower backward spatial-memory scores, particularly in men. No blood THC or driving impairment was measured.
Does the Same Wine Volume Worsen Night-Vision Tests More in Women? A 37-Person Study
A 37-person red-wine study found worsening halos, stereoacuity and contrast tests. Why higher breath alcohol—not sex alone—limits individual driving conclusions.
Can an Alcohol-Sensitive MedDrive Score Prove a Driver Is Impaired? What Two Validation Samples Show
A 2014 five-study MedDrive validation detected an alcohol-related cognitive change in 20 adults but weakly predicted 182 older drivers’ real-road ratings. Know the forensic limits.
Can Alcohol Lower Modeled Risk Tolerance While Working Memory Worsens? A 20-Person Trial
A 20-person randomized crossover trial found altered modeled lottery risk tolerance, harder n-back accuracy and TMS cortical silent periods after alcohol—without proving real-world judgment or BAC.
Can Alcohol Improve One Contrast Pattern While Worsening Others? A 20-Adult Vision Study
A 20-person controlled study found higher contrast sensitivity for some visual patterns but lower for others. Learn its evidence and forensic limits.
Can a Hangover Reduce Combined Multitasking Without Worsening Every Component? A 25-Person Study
A 25-person primary study found poorer overall four-task multitasking during hangover despite no significant separate module differences; workload rose, but differential stress reactivity did not.
Do Men and Women Show Different Driving-Related Effects of Alcohol and Energy Drinks at Similar Breath Alcohol Levels? A 28-Person Trial
A 28-person trial compared men and women at similar breath alcohol levels. See what tracking, reaction-time and subjective scores can—and cannot—prove.
Does Moderate Alcohol Affect Rejecting New Images Differently by Age? A 90-Adult Experiment
A 90-person controlled study distinguishes new-image rejection from recognizing old images at two breath-alcohol targets. Group data cannot diagnose individual impairment.
Does Near-Zero Breath Alcohol Rule Out Hangover-Related Memory Errors? A 41-Person Video Study
An original 41-person hangover study compared video-based prospective remembering and fruit verbal fluency despite near-zero breath alcohol. Learn the statistical findings and forensic limits.
Does Alcohol Make People Take More Risks—or Just Want Another Drink? A 142-Student Balloon-Task Study
A 142-student trial found more hypothetical balloon risk taking after alcohol. Learn why increased urge and mediation do not prove individual impairment.
Can a Hangover Confound Cognitive Tests at Zero Breath Alcohol? A 36-Student Retest
A 36-student test–retest found slower cognitive responses after reported hangover despite zero breath readings. Learn what it cannot prove in a legal case.
Does an Energy Drink Reverse Alcohol-Related Attention Errors? A 24-Person Trial
In a 24-person crossover trial, alcohol increased attention errors despite limited slowing. See why an 80-mg-caffeine energy drink did not reliably reverse impairment.
Does Alcohol Suppress the Brain’s Threat Response? A 49-Person fMRI Study and Its Forensic Limits
A 49-person randomized fMRI study found alcohol-linked BST changes. What breath testing and brain BOLD can—and cannot—prove about an individual’s fear or intent.
Does Alcohol Increase Impatience Without Increasing Risk-Taking? A 77-Person Decision Study
In a 77-person alcohol decision experiment, impatience changed while lottery risk-taking did not show a general increase. Read the BAC and legal limits.
Can Beliefs About Alcohol Change Stop-Signal Performance—and Prove Loss of Control?
Two alcohol experiments tested expectations, stop-signal performance, craving and drinking. Learn what changed, what did not, and why no legal loss of control follows.
Does PT150 Change Breath-Estimated Alcohol Levels? What a Ten-Man Safety Trial Shows
A ten-man PT150 alcohol trial found no detected breath-eBAC peak change. Learn why this does not establish blood BAC, drug safety, or DUI impairment.
Can Alcohol Change Eye-Tracking Patterns in a Maze? What a Blinded 20-Person Experiment Shows
A blinded 20-person alcohol-placebo study found more maze fixations and longer task time. Eye-tracking results do not establish individual BAC or driving impairment.
Does a Normal Stroop Interference Score Rule Out Alcohol-Related Slowing? A 40-Person Clamp Trial
A 40-person IV alcohol-clamp trial found slower Counting Stroop responses but no detected change in interference. Understand breath-derived aBAC and forensic limits.
Can Wine With Dinner Make Someone Feel Happier Without Proving Sobriety? A Controlled Mood Study
A 28-participant crossover study found that wine with dinner changed reported happiness and autonomic signals. Learn why neither proves sobriety or impairment.
Can You Feel Drunk With a 0.00 Breath Test? A Placebo Study
A 2017 alcohol-placebo study found lightheadedness with 0.00 breath readings. Learn what expectancy proves—and what it cannot prove about impairment.
