Our dear friends in Cambridge may be a little too loko over Four Loko.

In an e-mail sent to Harvard College students, the university’s health services director and its drug and alcohol czar together encouraged students to avoid the nasty nectar, which has drawn negative headlines this week after students at universities nationwide — including Harvard, the e-mail said — required medical treatment after consuming it.

“We strongly recommend that members of the Harvard community do NOT drink Four Loko and urge your friends to do the same,” wrote David Rosenthal, health services director, and Ryan Travia, drug and alcohol czar, in the e-mail.
