Having just googled it seems that scientists now believe moderate drinking doesn't give all the benefits they previously thought. That was mostly when compared with heavy drinking. Flawed methodology it seems.
But weed also seems pretty bad according to most of the latest studies. Obv at it's worst when smoked but even edibles can seemingly reduce vascular function to that of a cigarette smoker.
Whether It’s Smoking or Edibles, Marijuana Is Bad for Your Heart
A new study led by UC San Francisco researchers finds that chronic cannabis use — whether it’s smoked or consumed in edible form — is associated with significant cardiovascular risks.
The report, published May 28 in JAMA Cardiology, found that people who regularly used marijuana in either form had reduced blood vessel function that was comparable to tobacco smokers. Vascular function in those who used cannabis by either means was reduced roughly by half compared to those who did not use it.

Cannabis Users Face Substantially Higher Risk of Heart Attack
Two new studies add to mounting evidence that people who use cannabis are more likely to suffer a heart attack than people who do not use the drug, even among younger and otherwise healthy adults. The findings are from a retrospective study of over 4.6 million people published in JACC Advances and a meta-analysis of 12 previously published studies being presented at the American College of Cardiology's Annual Scientific Session (ACC.25).
Researchers found that cannabis users younger than age 50 were over six times as likely to suffer a heart attack compared to non-users. The meta-analysis, which is the largest pooled study to date examining heart attacks and cannabis use, showed a 50% increased risk among those who used the drug.

Smoking cannabis associated with increased risk of heart attack, stroke
The study, published in the Journal of the American Heart Association, uses data from nearly 435,000 American adults, and is among the largest ever to explore the relationship between cannabis and cardiovascular events.
The study, funded by the National Heart, Lung, and Blood Institute (NHLBI), part of NIH, found that daily use of cannabis — predominately through smoking — was associated with a 25% increased likelihood of heart attack and a 42% increased likelihood of stroke when compared to non-use of the drug.
