What action could a minor decoy take during an OLCC operation?

The action that a minor decoy could take during an OLCC operation involves attempting to purchase marijuana items using their own ID. However, it's important to clarify that while the decoy may be presented with a false ID or a similar tactic to observe compliance, minors are legally prohibited from purchasing marijuana under Oregon law.

In these operations, minor decoys are typically used by law enforcement to test the age verification processes of dispensaries and ensure that they are not selling to underage individuals. The focus is on checking if establishments comply with the laws regarding age restrictions. Purchasing using an ID would involve testing whether the staff at the establishment are properly checking IDs and refusing sales to anyone underage.

Though the correct response appears plausible in the context of testing compliance, the realistic implications of these operations mean that minors are not actually allowed to engage in any form of purchasing or selling of marijuana. The other options do not align with the lawful boundaries established for minors in relation to marijuana activities under Oregon's regulations.
