Digital Screening for Blood Alcohol Concentration (BAC) in a Southern Nigeria City

OBJECTIVE: Blood alcohol concentration (BAC) was digitally determined for transport operators, passengers, and pedestrians in a southern Nigeria city. METHODS: The subjects were screened with a digital breathalyzer, Alco Scan CA 2000, for BAC along major accident-prone highways, resting spots, and hospitals. The mouthpieces were complemented with disposable straws for rapid and hygienic screening of the subjects. RESULTS: Based on convenience sampling, a significant proportion of Nigerians has a BAC level above 0.06 on accident-prone highways (44.60%), at resting spots (54.50%), and in hospitals (47.80%). CONCLUSION: This research confirms that digital breathalyzer BAC levels are reliable and empirical means for determining incidents of alcohol-impaired driving.
