What is zenabrillatol?

Zennabrillatol, or sometimes listed as xennobrillotal, supposedly called by the street name zeebees or zenno, is a non-existent drug. It has been seen on several student health surveys asking "have you ever used the new drug zennabrillatol (or xennobrillotal depending on the survey)?" The question is meant to find out if a student is inflating their use of drugs, possibly for social reasons because they think it's "cool" to use drugs. These surveys are used to collect data on high school students' alcohol, tobacco, and drug use and the question is used to rule out invalid data.
