In a stern e-mail to Yale College students Tuesday afternoon, University officials strongly discouraged students from consuming “highly caffeinated alcoholic beverages” — namely, Four Loko.

Combining the caffeine equivalent of four to five cups of coffee with the alcohol content of five beers clouds judgment and leads to unintentional excessive drinking, Dean of Student Affairs Marichal Gentry and Chief of Student Health James Perlotto warned in their e-mail.

“This process can lead you to lose control unknowingly, causing extreme dizziness, vomiting, and due to the rapid intake of toxic levels of alcohol (without having had the natural warning signs, which were masked by caffeine), alcohol poisoning—meaning, in some cases, coma or death,” they wrote.

Gov. M. Jodi Rell announced yesterday that shipments of Four Loko would cease by Dec. 10, sending many students in a mad dash to Broadway Liquor in hopes of snagging the last few Lokos before they leave local liquor stores for good.
