Final answer:
The Controlled Item Inventory Code for substances that are classified as Schedule III, IV, or V is Code Q. This code helps classify and manage inventories of controlled substances according to federal regulations.
Step-by-step explanation:
The Controlled Item Inventory Code for substances that fall under Schedule III, IV, or V is Code Q. These codes are used to classify controlled substances as defined by the Drug Enforcement Administration (DEA) under the Controlled Substances Act (CSA). Schedule III drugs have a potential for abuse less than substances in Schedules I or II and abuse may lead to moderate or low physical dependence or high psychological dependence. Examples include anabolic steroids and some barbiturates. Schedule IV drugs have a lower potential for abuse relative to Schedule III substances. Examples include sleep aids like Ambien.
Finally, Schedule V substances have a lower potential for abuse than Schedule IV and consist primarily of preparations containing limited quantities of certain narcotics. Examples include cough preparations with less than 200 milligrams of codeine per 100 milliliters or per 100 grams (Robitussin AC, Phenergan with Codeine, etc.). When managing inventories of these substances, proper classification using Code Q ensures compliance with federal regulations.
