                                According to a study published in The Cochrane Database of Systematic Reviews, high doses of alcohol initially cause blood pressure to decrease, an effect linked to vasodilation. This initial response can lead to a mistaken belief that alcohol's effects on blood vessels are straightforward. The reality is more complex, involving a short-term expansion followed by a potentially more damaging long-term constriction.
