Can Energy Drinks Improve Some Alcohol-Affected Test Scores Without Restoring Driving Ability?
A 28-person crossover trial found partial improvements in some laboratory measures when an energy drink was added to alcohol. It did not demonstrate restored driving ability or complete reversal of alcohol effects.
What Can a 36-Report Audit Establish About Alcohol-Absorption Assumptions?
An audit found a two-hour post-absorptive assumption in all 36 reviewed reports. It examined reporting practice, not the subjects’ actual absorption curves or the error in each calculation.
Can a Cognitive Score Make an Older Driver Equivalent to an Intoxicated Young Driver?
MedDrive responded to alcohol in young adults, but older adults could have lower scores while driving well. Equal cognitive scores did not establish equal driving impairment.
Does a Lower Oral Alcohol AUC Prove the Stomach Metabolized the Missing Dose?
A physiologic modeling study shows why oral-versus-IV alcohol exposure differences cannot be read directly as gastric metabolism. The rate of delivery matters when elimination is nonlinear.
Does Alcohol-Related Difficulty Stopping Mean the Stop Cue Was Not Seen?
A controlled fMRI study separated processing of an infrequent visual cue from stopping an action. Its findings do not establish what a particular driver perceived.
Does 80% Wearable Accuracy Establish Alcohol-Impaired Driving?
A 28-person pilot classified alcohol-related labels from wrist signals. Its accuracy depended on the label, and neither classification was a direct test of driving.
Do Sex Differences After the Same Wine Dose Prove Different Visual Sensitivity?
In a 37-person vision study, women reached higher breath alcohol after the same wine volume. Exposure differences complicate claims about sex-specific visual susceptibility.
Can Memory for New Information Remain Poor the Day After an Alcohol Blackout?
A study of frequent blackout drinkers found deficits in some newly learned word-recall tasks the next day at zero breath alcohol. It did not validate a blackout claim or reconstruct a driver’s BAC.
Can a Better Cognitive Retest Reconstruct an Earlier Alcohol Level?
A student test–retest study shows why cognitive changes across days require information about hangover, sleep and practice. The score change is not a BAC reconstruction.
Does Looking More Often Mean Better Visual Search After Alcohol?
In a 20-person crossover study, alcohol increased eye fixations and maze completion time. More looking did not demonstrate more effective visual search.
Does the Most Alcohol-Sensitive Laboratory Test Best Predict Driving Impairment?
A 24-person alcohol-calibration study found particularly large effects on balance, but sensitivity to alcohol and prediction of driving performance are different scientific questions.
Can Alcohol Increase Driving Errors Without a Significant Rise in Simulator Crashes?
A 24-driver crossover study found more total errors with alcohol, while critical situations and collisions did not significantly increase. Why the endpoint and scenario matter.
Can Every Calculated BAC Use the Same Percentage Uncertainty?
An original uncertainty analysis shows why a Widmark calculation needs case-specific inputs rather than a universal percentage margin. Relative uncertainty can grow near zero.
Can a Validated Blood EtG/EtS Assay Prove Drinking Occurred Before a Crash?
A whole-blood EtG/EtS validation study supports reliable measurement, but not an automatic timestamp for drinking. Reporting cutoffs, matrix effects and case context matter.
Can Catch-Up Eye Movements Mask Alcohol-Related Loss of Smooth Tracking?
A 16-person study found reduced smooth pursuit with compensating catch-up saccades at low breath-reported alcohol levels. Why near-normal overall tracking does not mean every visual function is intact.
Does a Larger Brain Gamma Response After Alcohol Mean Better Performance?
A small MEG crossover study found larger gamma responses after alcohol alongside slower visual responses. Neural signal size is not a validated measure of driving fitness.
Do Sleeve Gastrectomy and Gastric Bypass Change Alcohol Exposure for Three Years?
A 33-person prospective study found faster, higher alcohol peaks after both procedures through three years. Plasma outcomes, fixed doses and attrition limit DUI extrapolation.
Does a Strong Blood–Breath Alcohol Correlation Make the Results Interchangeable?
A 100-volunteer reanalysis found a strong blood–breath correlation but variable ratios. Why group agreement cannot supply a driver’s exact blood alcohol concentration.
How Can Gender-Affirming Hormone Treatment Affect a Calculated BAC?
A 2022 modeling study examined body-water assumptions in alcohol calculations after hormone treatment. Its proposed equations were estimates, not validated individual BAC measurements.
Can Stadium Alcohol Surveys Establish How Many Spectators Drove Impaired?
A 4,420-spectator study measured alcohol during Swedish football matches. Why its drinking rates cannot establish DUI prevalence or a fan’s departure BAC.
Does Alcohol Affect Recognizing Old Images Differently From Rejecting New Ones?
A 90-person study found alcohol effects depended on age, dose and whether images were old or new. Why selected benefits and null findings cannot establish driving fitness.
Can Fingertip Blood Give a Lower Alcohol Result Than Venous Blood?
A 13-volunteer study found lower fingertip ethanol than venous ethanol one hour after drinking. Why the average difference is not a universal BAC correction.
Can Hangover Lower a Combined Multitasking Score When Individual Tasks Show No Significant Change?
A 25-person crossover study found a lower combined multitasking score during hangover, without significant component-task differences. Why effort, sleep and zero breath alcohol need separate interpretation.
Can Alcohol Slow a Stroop Test Without Worsening Its Inhibition Score?
A 40-person alcohol-clamp experiment found slower Counting Stroop responses but no increased interference. What the positive and null findings mean for DUI interpretation.
How Much Did Alcohol Increase Lane Weaving in a 17-Driver Simulator Trial?
A randomized crossover trial found greater lane weaving at about 0.07% breath-reported BAC. The low-dose null result, confidence ratings and unmeasured driving-time BAC matter.
Can a Hangover Disrupt Remembering What to Do Next? A 41-Person Study
A 41-person observational study linked hangover with poorer future-action memory and verbal fluency. Why a near-zero breath result does not settle functional capacity.
Can Faster Answers After Alcohol Hide Less Accurate Visual Judgments?
A visual-number experiment found faster responses but lower accuracy after alcohol. What its breath-derived values and reporting limitations mean for DUI evidence.
Hospital Alcohol Tests in DUI Cases: Serum Results, Uncertainty and Threshold Decisions
A 2017 study shows why hospital serum alcohol results near a DUI threshold require laboratory-specific uncertainty analysis—and why 19.74% is not a universal BAC deduction.
Midazolam Clearance in Children: Why the Average Does Not Identify the Individual
A published average clearance is not a measurement of the child in front of you. That distinction matters when interpreting midazolam concentrations in pediatric intensive care. A population estimate describes the patients and methods that produced it; applying it to another patient requires evidence that the comparison fits. What the uploaded review found Altamimi and…
Early Remimazolam Sampling: What a Population Clearance Estimate Can Establish
A population clearance estimate summarizes a fitted pharmacokinetic model. It is not a direct measurement of how quickly every patient eliminates a drug, and its interpretation depends on when samples were collected and which model parameters were estimated. A 2025 remimazolam study by Ueshima and colleagues illustrates these limits. The investigators measured drug and metabolite…
