Stanford made an update to its student alcohol policy in a website post Monday.

NPR reported that the change means that hard liquor is completely banned from on-campus parties unless it's part of mixed drinks for a party that is only for graduate students.

"Straight shots of hard alcohol are never allowed at any party," the update said. "Beer and wine are the only alcoholic beverages that can be present at all on-campus undergraduate student parties."

"Our intention is not a total prohibition of a substance, but rather a targeted approach that limits high-risk behavior and has the backing of empirical studies on restricting the availability of and access to alcohol," according to the policy update.

Stanford professors Michele Dauber and Adrian Daub slammed the policy change, saying that in the wake of former Stanford swimmer Brock Turner being given a "light sentence" of six months in jail following rape charges, it appears the school is blaming drinking for sexual assault and rape, rather than addressing issues of consent.

Dauber previously asked for a recall of Aaron Persky, the judge she said was too lenient with Turner based on his sentence.

Turner said in a statement to the judge at the time that he "made a mistake" because he "drank too much," citing peer pressure and "the culture surrounded by binge drinking and sexual promiscuity that protrudes through what people think is at the core of being a college student."

The new policy is effective immediately.
