When preparing training aids, what is meant by 'Charged'?

The term 'Charged' in the context of preparing training aids refers to the quantity of vapor of narcotics within the item. This is crucial for training narcotics detection K9s, as the animals are trained to detect not only the physical presence of narcotics but also the scent or vapor that emanates from them.

When an item is described as 'charged,' it indicates that the item has been purposefully infused or impregnated with the scent of narcotics, allowing the K9 to practice their detection skills effectively. It is important that this vapor is consistent in quantity and quality to facilitate accurate training scenarios.

Items that merely contain narcotics or are placed in an airtight container may not adequately simulate the scenario the K9 would encounter in the real world, where narcotics may not always be fully accessible or contained. Therefore, the focus on vapor detection ensures that the K9 develops the necessary olfactory skills needed for effective field work.
