Final answer:
When controlled drugs are no longer needed by a patient, they should be properly disposed of through drug take-back programs or alternative methods to prevent environmental pollution and potential misuse.
Step-by-step explanation:
When controlled drugs are no longer needed by a patient, it is important to properly dispose of them to prevent environmental pollution and potential misuse. One recommended method of disposal is through drug take-back programs, which are available in some countries. These programs allow individuals to return unused or expired medications to designated collection sites, where they are then disposed of safely.
If drug take-back programs are not available, there are alternative methods of disposal. The U.S. Food and Drug Administration recommends mixing the medications with an undesirable substance, such as kitty litter or coffee grounds, and sealing them in a plastic bag before throwing them in the trash. It is important not to flush medications down the toilet or sink, as they can contaminate water sources.
Proper disposal of controlled drugs helps protect the environment and ensures they do not end up in the wrong hands. By following the recommended methods, individuals can contribute to a safer and healthier community.
