What should not be done with a druggist fold when packaging evidence?

Using tape to seal a druggist fold when packaging evidence is not recommended because it can compromise the integrity of the packaging and the evidence itself. Tape can make it difficult to open the fold without damaging the contents or can introduce contaminants. The purpose of a druggist fold is to securely contain small amounts of evidence without the need for additional sealing tape, as the fold itself is meant to protect the evidence from loss or contamination.

In contrast, marking the fold with evidence identification, storing it in a secure envelope, and labeling it clearly are all essential steps in the chain of custody that ensure the evidence is properly identified and can be tracked throughout the investigation and legal process. Proper procedures help maintain the credibility of the evidence and its admissibility in court.
