About DUI Pro

DUI Professional is a blood alcohol extrapolation and BAC simulation platform for legal, forensic, training, and education workflows. Presets can be adjusted by qualified professional users, including toxicologists and expert witnesses.

DUI Pro was initially developed in 1997 out of frustration in performing the time-consuming and complicated process of calculating retrograde extrapolation. DUI Pro 98 was released in 1998 as a Windows application and became an early BAC simulation tool for professional alcohol analysis. 

A unique feature of DUI Pro stemmed from the author's teaching at the Florida Department of Law Enforcement on DNA analysis of human remains and the legal requirement that scientific evidence have measurable reliability.

The few blood alcohol analysis tools deployed by experts did not factor in the variance in elimination (non-drinkers versus alcoholics), absorptive factors (delay in metabolizing drinks) and distribution constants. However, a substantial number of peer-reviewed scientific studies quantified these error ranges.

Range-based blood alcohol simulations had practical utility because they helped users see how assumptions changed the values provided. DUI Pro 98 was licensed by many entities including branches of the U.S. Armed Forces, medical schools around the world, DUI defense attorneys, addiction counselors and expert witnesses. As technology advanced, the DUI Pro 98 lifecycle concluded with the introduction of 64-bit operating systems. However, with that product sunset a new opportunity arose.

DUI Pro Online expands the drink database from 200 to over 1,000 drinks. The database is searchable by drink type and/or brand name. Licensed users can add their own drink profiles which are exclusive to their private login credentials. Another exciting feature of DUI Pro Online is the use of asynchronous Javascript to provide real-time calculations of BAC immediately responsive to changes in variables such as drinking time, weight, biological sex, and related assumptions. This supports retrograde extrapolation review and scenario comparison.

Reports are detailed enumerating the methodology and are downloadable as Adobe PDF files which can be emailed, saved or printed as desired. DUI Pro is not a "drink calculator" but a scientific tool and resource for law enforcement, criminal defense, counseling, medical research and occupational safety.
