From the article:
The upper safe limit of drinking was about 5 drinks per week (100g of pure alcohol, 12.5 units or just over five pints of 4% ABV2 beer or five 175ml glasses of 13% ABV wine).
However, drinking above this limit was linked with lower life expectancy. For example, having 10 or more drinks per week was linked with 1-2 years shorter life expectancy1. Having 18 drinks or more per week was linked with 4-5 years shorter life expectancy.

The researchers also looked at the association between alcohol consumption and different types of cardiovascular disease. Alcohol consumption was associated with a higher risk of stroke, heart failure, fatal aortic aneurysms, fatal hypertensive disease and heart failure and there were no clear thresholds where drinking less did not have a benefit.
