These no alcohol signs and no drugs signs are ideal for schools and other facilities that want to crack down on drug and alcohol use. Schools are places of learning and should be a safe haven for children from negative influences such as drugs, alcohol, tobacco and weapons. Post these no alcohol signs on your campus to declare it a drug, alcohol, tobacco and weapon free zone. Creating a safe environment fosters learning and helps children focus their education. Placement at the entrances to your school and around the campus will make all who visit aware of your policies.
