What kind of identification must be checked by marijuana workers?

The correct answer highlights the importance of verifying the customer's identification in a marijuana retail setting. In accordance with OLCC regulations, employees must ensure that customers are of legal age to purchase cannabis products, which is typically set at 21 years or older in Oregon. By checking the customer's identification, workers are taking necessary steps to adhere to legal requirements and promote responsible consumption of cannabis.

This practice is significant because it helps prevent the sale of marijuana to underage individuals, thereby contributing to both public safety and compliance with state laws. It empowers employees to uphold the integrity of the cannabis industry and reinforces the responsibility that comes with working in this regulated environment. Checking for valid identification is not only a legal obligation but also a fundamental aspect of ensuring that the business operates within the guidelines established by the OLCC.
