It's all about heavy drinking when out on the town in the UK. The report contains this bit of information that would suggest letting people know their BAC is not a good way to get them to drink less:
Just over half (51%) of the people who reported feeling drunk at interview said they intended to drink more alcohol that night. The researchers also found that when individuals were informed about their blood alcohol level, it was more likely to encourage them to drink (nearly 1 in 4) than to reduce their alcohol consumption that night (less than 1 in 25). Bellis said, "Commercial use of breathalyzers to encourage individuals to drink more has already been attempted in some bars in the UK. As such technologies become more easily accessible there is a real danger it will further increase alcohol consumption."Oh well. I can always thank a stomach that is more than ready to throw up after its allocated share of alcohol for ensuring I am in absolutely no danger of ever going out to attempt 40 units of alcohol in a night. On the assumption a bottle of wine is about 7 standard drinks, I'm not sure I've even reached 10 or 12 in an evening without vomiting. ( Just thought I would share that with you.)
