In a study in the Journal of American College Health (2010, v.57, 3, p.380), Green Zone® Cards were cited by physicians as useful clinical tools when conducting brief interventions with college students. The author of the study, Dr. Elizabeth Rash, suggested that the Cards "may facilitate shorter primary care visits." When dealing with such a critical topic as alcohol risk prevention, it's important to have a team of people who are constantly looking after your best interests. Our team stays abreast of all the latest research to help you continue making healthy lifestyle decisons.

The BACZONE formula takes into account some important changes in BAC calculations established over time by agencies of the federal government. Based on this ongoing research, we have adopted somewhat more “conservative factors concerning the level of blood alcohol concentration and how long it takes for alcohol to be metabolized. Our current formula is based on a modified Widmark Formula used by the National Highway Traffic Safety Administration. This formula uses a more conservative “burn off" rate or rate at which alcohol is metabolized than formulas used in other alcohol education products.
Abiding By the Latest Industry Standards
Another major factor in our formula is the measure of what is called a “standard drink." The National Institute on Alcohol Abuse and Alcoholism defines a standard drink to be .6ozs of pure alcohol instead of .5oz, so we adjusted our formula to reflect this change. Other providers use and outdated formula. Using .6oz as a standard drink corresponds to a 12 oz beer with 5% alcohol, 5ozs of wine with 12% alcohol, and a 1.5 oz shot of 40% alcohol.
Getting the Best Results
As mentioned elsewhere on this site, a number of studies have shown that drinkers tend to underestimate the amount of alcohol in their drinks. We believe the BAC estimates generated by adjustments in our formula, while perhaps higher than some generated by other products, will help individuals make safer and lower risk choices and ultimately promote a healthier lifestyle.
