 Which Fans Drink the Most on Game Days?




BACtrack analyzes anonymous Blood Alcohol Content (BAC) data to gain insight into alcohol consumption patterns and create a dialogue around BAC.

Here we examine NFL fans' average BAC levels for Sunday games for the 2017 season through Sunday, December 3rd.

We used Twitter's map of NFL fan allegiance in order to associate BAC results with NFL teams across the country. BAC data points are collected anonymously from users of BACtrack Mobile, BACtrack's award-winning smartphone breathalyzer.

NFL Fans with the Highest Average BAC Levels

Cowboys fans' average BAC level was the highest at 0.062% followed closely by Patriots' fans at 0.061%.

What do these top 5 teams have in common? A win percentage of 50% or higher over the last 10 years. Read on to see how higher average BAC levels correlate with a team's 10-year win percentage.

NFL Fans with the Lowest Average BAC Levels

Fans of these five East Coast NFL teams have the lowest average BAC levels on game days -- they're more than 50% lower than the highest average BACs. 

The Highs and the Lows

From 0.024% up to 0.062% BAC, there's a wide range of imbibing on game days.

While these BAC levels are below the legal limit of 0.08%, it's important to note they're still unsafe levels at which to drive. It's dangerous to have any amount of alcohol in your system when driving.

How Many Drinks Does it Take to Get to 0.08%?

The short answer: it varies every time you drink. Factors like gender, metabolism, rate of consumption, and whether or not food was consumed while drinking all impact your BAC. (This is why a BACtrack is such a necessity!)

Previous BACtrack Consumption Reports


We utilized Twitter's map of NFL fan allegiance in order to associate BAC results with NFL teams across the country. (Note adjustments were made due to team relocation).

How a BACtrack Works

When alcohol is consumed, it is absorbed from the mouth, throat, stomach, and intestines into the bloodstream.

As blood flows through the lungs, alcohol in the bloodstream moves across the membranes of the lung’s air sacs (alveoli) into the air. The concentration of the alcohol in the alveolar air is directly related to the concentration of the alcohol in the blood. As the alveolar air is exhaled, the alcohol in it can be detected by the breath alcohol testing device.

BACtrack Mobile and BACtrack Vio

All data in this study was collected from the BACtrack Mobile, BACtrack's award-winning, police-grade smartphone breathalyzer and BACtrack Vio. When a user blows into BACtrack Mobile or BACtrack Vio, BAC results are wirelessly transmitted via Bluetooth® to an iOS or device. With the free BACtrack companion app, a user can get more than a BAC result -- they can track, save and share BAC results, call an Uber, and with BACtrack's ZeroLine® feature, get an estimate of when their BAC will return to 0.00%.
