The holidays are coming up, and with them come holiday parties, and with holiday parties comes booze, and with booze comes all sorts of studies about how booze is scary. Just last week, we learned that drunk people like to hook up at the aforementioned holiday parties, and today, we are told that drunk people, when hooking up, might have unsafe sex due to being drunk. Thanks, science!

A new study in an upcoming issue of the journal Addiction concludes that the more alcohol participants consumed, the higher their willingness was to engage in unsafe sex, no matter what their personality is when sober. Until now, researchers apparently didn't know if people who are "predisposed to engage in risky behavior," like heavy drinking and hotwiring cars for midnight joyrides, were simply more likely to forgo the condoms, or if alcohol can make even normally boring folks forget to cover it up.

"Drinking has a causal effect on the likelihood to engage in unsafe sex, and thus should be included as a major factor in preventive efforts for HIV," concluded Dr. J. Rehm, the lead researcher on the study. "This result also helps explain why people at risk often show this behavior despite better knowledge: alcohol is influencing their decision processes," he added. The Centre for Addiction and Mental Health in Toronto, which sanctioned the research, is currently funding a study to determine if there's anything left worth studying. [via Fork in the Road]
