About Blood Alcohol Content (BAC):
- • BAC measures the percentage of alcohol in your bloodstream.
- • The legal driving limit in most places is 0.08%, but impairment begins at lower levels.
- • Your body metabolizes alcohol at approximately 0.015% per hour.
- • Many factors affect BAC including gender, weight, food consumption, and medications.
- • Different types of drinks can contain varying amounts of alcohol.
Common Drink Standard Measures:
- • Beer (5%): 350ml (12 oz) bottle or can
- • Wine (12%): 150ml (5 oz) glass
- • Spirits/Shots (40%): 45ml (1.5 oz) shot
- • Cocktails: Vary widely, but often contain 1-3 shots of alcohol
