• 340 mL bottle of light beer (3.7% alcohol) = 0.7 standard drinks
• 355 mL can of extra strength beer (8% alcohol) = 1.7 standard drinks
• 500 mL can of cider (4.5% alcohol) = 1.3 standard drinks
• 750 mL bottle of wine (12% alcohol) = 5.3 standard drinks
• 9 oz glass of wine (14% alcohol) = 2.1 standard drinks
• 2 oz shot of spirits (40% alcohol) = 1.3 standard drinks

Reduce your alcohol-related health risks² by drinking no more than:

• 10 drinks a week for women, with no more than 2 drinks a day most days.
• 15 drinks a week for men, with no more than 3 drinks a day most days.

Plan non-drinking days every week to avoid developing a habit. On special occasions, reduce your risk of injury and harm by drinking no more than 3 drinks (for women) or 4 drinks (for men) on any single occasion.
