A drug that was described in a question on the Georgia Student Health Survey for students 6-8 grade and 10-12

grade. The drug is believed by many to be ficticious. The drug is not mentioned on any other websites unless it is someone asking what the drug is. The drug is said to have the street name ZB, however, many claim to have never heard of it. Mostly likely the drug was created to make sure students taking the survey were giving honest answers.

“10. Have you ever used the drug zenabrillatol (street name ‘ZB’)?”

Girl 1: What is ZB?

Girl 2: Never heard of it.
