Here is what the Escambia County student manual says about drugs under Zero Tolerance. There is no special section for alcohol:
Drugs: The unlawful use, possession, or sale of a controlled substance as defined in Chapter 893 Florida Statutes by any student while the student is upon school property, at a school bus stop, or while in attendance at a school function shall result in the student’s expulsion and may result in criminal penalties being imposed.
Just in case you are wondering, I also looked up Chapter 893 Florida Statues
“Controlled substance” means any substance named or described in Schedules I-V of s. 893.03. Laws controlling the manufacture, distribution, preparation, dispensing, or administration of such substances are drug abuse laws.
