This article says, “the blood of people who consume 3 to 6 drinks weekly was less likely to clot in a test tube than was the blood from nondrinkers.” I wonder if there is a rebound effect that could make the blood of new abstainers even more likely to clot than that of regular nondrinkers. In other words, if one abruptly stops drinking, is that a temporary added risk?
