The Claim
A 6-week reduction in alcohol intake from an average of 336 ml of ethanol per week to 20% of baseline significantly lowers both systolic and diastolic blood pressure in normotensive men, with systolic pressure decreasing by 3.8 mm Hg during the final two weeks of reduced intake.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In normotensive men, reducing alcohol consumption from 336 ml of ethanol per week to 20% of that amount for six weeks results in a 3.8 mm Hg decrease in systolic blood pressure during the final two weeks and a reduction in diastolic blood pressure.

When alcohol is consumed, it triggers the nervous system to release more norepinephrine, which tightens blood vessels. This makes it harder for blood to flow, raising the pressure inside the arteries. When alcohol intake is reduced, this tightening effect decreases, and blood pressure drops.
What the research says
1 studyWhen men who regularly drank alcohol cut their intake by 80% for six weeks, their blood pressure went down — even after accounting for weight loss. When they started drinking normally again, their blood pressure went back up.
