BACtrack Consumption Report - Summer 2015

For the fourth time, BACtrack shares consumer Blood Alcohol Content (BAC) data for review and analysis. The data provides insight into alcohol consumption patterns around the nation, and is regularly updated and analyzed.

In this report, we examine average BAC (Blood Alcohol Content) levels during the Summer months of June, July and August 2014. The data was gleaned from over 71K unique BAC tests that were collected anonymously from users of BACtrack Mobile, BACtrack's award-winning smartphone breathalyzer, and BACtrack Vio

    When Do Americans Drink the Most During Summer?

    It’s no surprise that many Americans spend their summers floating down rivers or cruising across lakes with drinks in hand. According to BACtrack data, the summer booze cruise starts and ends on a high note, only declining slightly towards the end of July.

    • The Summer Solstice, the official start of summer, and July 4th are tied for the booziest days, with an average BAC of 0.082%.
    • Over 47% of days throughout the summer months (June, July and August) have an average BAC above 0.060%, the national average throughout the entire year.
    • 8 of the 13 biggest drinking days of the summer are Saturdays, with average BACs between 0.075% and 0.082%.
    • There are five summer days with an average BAC above the legal limit of 0.080%: June 7, June 14, June 21, July 3, and July 4.

      Americans Celebrate their Independence by Drinking

      Nothing says “America” like a good drink and some red, white and blue.

      • The 4th of July is tied with the Summer Solstice as the booziest day of summer, with an average BAC of 0.082%.
      • July 3rd comes in at a very close second, with an average BAC of 0.081%.
      • The week leading up to the fourth of July is the booziest week of the summer, with an average BAC of 0.075%. No other week has an average BAC over 0.070%.
      • July 4th is one of the most dangerous times on the road. According to a ​recent National Highway Traffic Safety Administration​ ​stud​y​, ​8.3% of drivers during weekend nighttime hours were found to have alcohol in their system​.​​ Based on this study and our analysis of user data, ​we estimate the percentage of people with a positive BAC roughly triples on July 4th vs​.​ other non-holiday weekend nights​ -- one out of every four drivers on the road has consumed some amount of alcohol.

      Most Sober Days of Summer

      BACtrack found the summer days with the lowest average BACs are Mondays and Tuesdays, and that Americans drink the least at the end of July but then regain their drinking stamina throughout August.

      • Tuesday, August 5th registered the lowest average BAC of 0.034%, followed by Monday, July 21st (0.039% average BAC), Monday, June 9 and Monday Aug 4 (both 0.040% average BAC).
      • Looking at weekly BACs, the lowest average BAC was the last week of July, which registered at 0.058%.
      • Americans increase consumption again the following week, at the start of August, with an average BAC of 0.061%.

        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 Smartphone Breathalyzers

        All data in this study was collected from the BACtrack Mobile, BACtrack's award-winning smartphone breathalyzer with police-grade Xtend®Fuel Cell Sensor Technology, and BACtrack Vio, BACtrack's newest smartphone breathalyzer model. When a user blows into BACtrack Mobile or BACtrack Vio, BAC results are wirelessly transmitted via Bluetooth® to an iOS or Android device, including Apple Watch. With the free BACtrack companion app, a user can get more than a simple BAC result -- they can track, save and share BAC results, attach a note or photo to a result, and with BACtrack's ZeroLine® feature, get an estimate of when their BAC will return to 0.00%.
