Final answer:
Schedule III drugs can be stored outside of the dispensary and require a pharmacist for assistance as they have a moderate to low potential for physical and psychological dependence.
Step-by-step explanation:
The schedule of a drug refers to its classification under the Controlled Substances Act based on its potential for abuse, medical use, and safety or dependence liability. Schedule III substances can be stored outside of the dispensary but require a pharmacist to be available to offer assistance. Schedule III drugs have a moderate to low potential for physical and psychological dependence. Schedule I drugs have no accepted medical use and are not available for prescription. Schedule II drugs have a high potential for abuse and are available only through a non-refillable prescription. Schedule IV drugs have a low potential for abuse relative to Schedule III drugs.
