Breath Analyzer Market size was USD 615.1 Million in 2022

The global breath analyzer market size was USD 615.1 Million in 2021 and is expected to register a revenue CAGR of 17.5% during the forecast period. Technological improvements in drug and alcohol testing equipment, as well as stringent government regulations, are driving the breath analyzer market revenue growth. The most common reason for traffic accidents is drunk driving. According to research, countries with the most numbers of drunk driving are South Africa with 58% of the global accidents, followed by Canada with 34%, the U.S. with 31%, Australia with 30%, France with 29%, Italy with 25%, and others. On 18 December 2020, according to the National Highway Traffic Safety Administration (NHTSA), drunk driving claimed the lives of 10,142 individuals in 2022 in Washington D.C. alone, accounting for 28% of the 36,096 overall fatalities.

Blood Alcohol Concentration (BAC) denotes the level of intoxication used to determine the driver’s blood-alcohol level. Most countries established a legal limit of 0.08 grams of alcohol per 100 milliliters (ml) of blood (BAC 0.08) as it is the point at which a driver is deemed to be legally intoxicated. Any driver whose blood alcohol content is greater than 0.08 is deemed to be inebriated while operating a vehicle and is not permitted to do so. For instance, in Sweden, the legal limit for BAC is 0.02%; in Israel, Korea, and Australia, it is 0.05%; and in Canada, England, Mexico, and the U.S., it is 0.08%. Driving while intoxicated is punishable in various countries, and in China, if the driver’s blood alcohol concentration is 0.02% or above. According to the NHTSA, drinking and driving kill 28 people in the U.S. every day, or one in every 52 minutes. Every year, more than 10,000 lives are lost due to drunk driving. Despite reduced traffic on the roads due to the pandemic, alcohol-related crashes increased by 9% in 2020 compared to 2022. Laws have been implemented to prohibit driving after drinking and severe penalties are imposed on violators. On 29 August 2022, the government of India, under its new law increased the penalties for drunk driving to up to six months in prison or a penalty of USD 128.14 (INR 10,000) for the first offense and two years in prison or a penalty of USD 192.21 (INR 15,000) for a subsequent offense. In the U.K., violating the rule against drinking and driving can result in a jail sentence, a fine of up to USD 5,000, and a minimum 12-month driving ban. The minimum driving ban is three years if a person is found guilty second time within 10 years. To keep a check on drunk driving, law enforcement is using breath analyzers extensively to limit road accidents.

The alcohol content in the exhaled air is measured by the change in color of the solution. The amount of alcohol present in the breath can be measured by calculating the BAC, which is supposed to be 2,100:1. Alcohol changes the reddish-orange potassium dichromate solution in the Breathalyzer to green. For instance, 2,100 ml of alveolar air will have an alcohol content of 1 ml of blood. On 16 August 2022, Y Combinator, which is an investment company, invested in SannTek Labs to work on a new kind of breathalyzer. This breathalyzer is designed to detect blood alcohol levels as well as the type of cannabis a person has consumed in the past 3-4 hours. Advancements in technologies and such innovations are driving revenue growth of the market. However, breathalyzers are not always accurate. They can sometimes fail to distinguish between alcohol and other specific chemical substances that may be present. For instance, methyl-containing substances, vinegar, and even the breath of a diabetic patient can result in erroneous testing, which hampers their adoption.

Market Dynamics:
Driver: Increasing adoption of breath analyzers in various medical applications

Infrared breath analyzers replaced chemical crystal-based breath analyzers owing to recent advancements made in breath analyzer technology, which has improved its accuracy in determining the amount of alcohol in a breath sample, which is the key factor driving revenue growth of the market. Breath analysis offers a relatively inexpensive, rapid, and non-invasive method for detecting a variety of diseases. It is possible to identify thousands of different molecules, including volatile organic compounds and elemental gases in the breath owing to recent developments in Mass Spectrometry (MS) and Gas Chromatography (GC-MS). The identification of trace gases in a human breath at the parts per trillion level is made possible by more sophisticated technologies, including Selected-ion Flow-tube Mass Spectrometry (SIFT-MS), multi-capillary column ion mobility MS (MCC-IMS), and proton transfer reaction MS (PTR-MS). Breath sampling is simple and painless, no specimens are transferred to a lab, waiting for results, and no mixing or handling of fluids is required, making it more convenient, efficient, and cost-effective than blood and urine-based testing systems. Breath-based research is also being done to diagnose breast cancer and heart disease, as well as to detect glucose levels in blood. Diabetics need to self-monitor their blood glucose levels in order to calculate medicine dosage and maintain healthy glucose levels. For diabetics, a breath-based monitoring system would make glucose testing painless and significantly more convenient. On 13 December 2021, scientists developed an RNA-based breath test known as bubbler to detect COVID-19. The Bubbler can barcode that DNA, enabling samples to be directly linked to the patient from where they originated and use for sequencing. It is used for concurrent batches of pooled samples, gives further details such as viral load and strain identity, and does not require sample stabilization.

Increase in stringent regulations for alcohol tests during driving to reduce the number of accidents taking place daily is one of the major factors driving revenue growth of the market. Drunk driving puts the driver, the passenger, and pedestrians in danger, approximately one-third of fatal crashes, accidents, and deaths take place owing to drunk driving. According to the Road Accident Report 2022, in India, there were 449,002 incidents in 2022 that resulted in 151,113 deaths and 451,361 injuries. The number of accidents dropped by 3.86% in 2022, while the number of accident-related fatalities and injuries dropped by 0.20% and 3.8%, respectively. On 23 December 2021, 25,453 drunk driving cases were reported during the course of the year, and 206 people received prison sentences. In spite of a number of tough laws and regulations, drunk driving remains one of the main causes of traffic accidents.

Restraint:  Lack of awareness and limited device accuracy

Interfering chemicals such as ethyl alcohol, and isopropyl alcohol pose a significant problem for alcohol breath analyzers. Diabetics have high acetone levels, which can cause breath analyzer findings to be falsely positive. When testing a new device without drinking, breathalyzers exhibit high false-positive readings of +0.012 BAC % to +0.018 BAC %, due to presence of ethyl alcohol in hand sanitizer, which influences sensors embedded in the breathalyzer. Moreover, chemicals present in several popular cleaning fluids have led to erroneous results when absorbed through skin. From 0% to 0.421% weight per volume (w/v), blood alcohol concentrations were measured. Alcohol concentrations in the breath ranged from 0 to 0.44 g/210 L. 0.16 g/210 L was the average Breathalyzer reading. The average blood alcohol level came up at 0.176% weighted. Breathalyzer results differed from the blood-alcohol result by more than 0.01 g/210 L 61% of the time, within 0.01 g/210 L 33% of the time, and by more than 0.01 g/210 L 6% of the time.

COVID-19 Analysis:

The COVID-19 pandemic had an impact on businesses around the world. To slow the spread of the pandemic, governments around the world imposed tight lockdown measures and social distance standards. The InspectIR COVID-19 Breathalyzer was frequently used during COVID 19. It instantly detects five volatile molecules linked to SARS-CoV-2 infection in exhaled breath and separates and analyses chemical combinations using a technique known as gas chromatography-mass spectrometry (GC-MS). When the SARS-CoV-2 VOC markers are found by the InspectIR COVID-19 Breathalyzer, a presumptive positive test result is reported, which can be confirmed by a molecular test. On 3 May 2022, Frisco startup received the U.S. Food and Drug Administration (FDA) approval for COVID breathalyzer after teaming up with UNT researchers. This significant approval offers a rapid, simpler, and accurate approach to COVID-19 detection. As the first intellectual property from UNT to achieve FDA approval, this is a major accomplishment for UNT as a Tier One research university.

Key Takeaways
Technology Outlook: 

Based on technology, the global breath analyzer market is segmented into fuel cell technology, semiconductor sensor, infrared spectroscopy, laser-based spectroscopy, and others.

Semiconductor sensors are precise if the breath temperature is consistent and there are no other volatile substances in the circulation that could interfere with the measurement of the BAC level. It means that chemical compounds other than alcohol are detectable by semiconductor sensors such as mouthwash. Semiconductor sensor units are comparatively inexpensive and are popular as personal breathalyzers for conducting low-volume testing. They usually have an accuracy range of +/-0.01% BAC and can read numbers up to two decimal places.

The laser-based spectroscopy segment is expected to register a moderate revenue growth rate during the forecast period. With detection limits ranging from parts-per-million (ppm, nmol/mol) to less than part-per-billion (ppb, nmol/mol), laser spectroscopy detects single or many volatile chemicals at sub-second time resolution and breath-cycle resolution. The high precision, absolute accuracy, and breath-cycle resolved sampling enable significantly more collection of data and thorough biomarker research.

Application Outlook:

Based on application, the global breath analyzer market is segmented into drug abuse detection, alcohol detection, and medical applications. The alcohol detection segment is expected to register a steady revenue growth rate over the forecast period. Law enforcement officers have utilized breathalyzers to accurately estimate blood alcohol content. Alcohol measured by an evidential breath analyzer may be admissible in court for prosecution of Driving While Intoxicated (DWI), depending on the condition of the driver. Blood alcohol assessed by Gas Chromatography (GC) is subject to relatively little interference while breath alcohol may be impacted by several interfering compounds. For instance, in the U.S., evidence-based breath analyzers used by law enforcement and approved by the NHTSA are trustworthy and admissible in court.

The medical applications segment is expected to register a moderate revenue growth rate over the forecast period owing to the recent advancements made in breath analyzer technology. A breath analyzer is a low-cost and effective tool for detecting a wide range of disorders.
