Blood Alcohol Concentration (BAC)

Hi everyone,
I was wondering if anyone knew what are the variables that determine Blood Alcohol Concentration? (BAC)
Does weight and health have any significant impact on BAC?

The list of variables is really quite broad.

Commonly cited factors are:
- gender;
- build;
- the amount of sleep a person has had; and
- the timing and volume of food they've eaten.

A good friend of mine has just gone and purchased a breathalyzer for his car.
Is he paranoid about being slightly over the limit or is this a really good idea?

Do does anyone know how much one of these machines would cost? I'd consider getting one to share with my family if I had some idea of cost and an understanding of how useful / accurate it would be.

You should bear in mind that blood alcohol readings can vary considerably.

You could find yourself under the limit when you get in the car. However if all the alcohol had not been registered in your system, you could find yourself over the limit a little while later.

There are a lot of risks to your friend's approach.
