Controlled substances are drugs that have a high abuse potential and that must be regulated to help prevent those abuses (Figure 16-1). The Controlled Substance Act of 1970 was passed to reduce drug abuse by restricting certain substances with a high abuse potential. The act was established, and is controlled by, the Drug Enforcement Agency (DEA) and provides approved means for proper manufacturing, distribution, dispensing, and use through licensed handlers.

MANAGEMENT OF CONTROLLED SUBSTANCES
Figure 16-2 shows that 12 bottles of Telazol were received on August 4, 2000. Initially, there were no bottles available for use. Once the 12 bottles were added, the initial amount became 12 bottles. The bottles were assigned the numbers 100 through 112; these were the next numbers in sequence (99 bottles had been previously used). The stock supply list states that bottles were checked out to the surgical plain on August 5, 8, and 10 by two team members. Each time bottles are checked out, they must be recorded on this list and initialed by the team member removing the bottle.
