The Oregon Liquor Control Commission has increased the penalties for selling marijuana to minors at licensed shops.

The temporary rule was approved Thursday.

The penalty is now a 30-day license suspension or a fine of $4,950 for a first-time offense of the unintentional sale of marijuana to a minor. The penalty had been a 10-day suspension or $1,650 fine.

The rule took effect Friday. OLCC staff will review compliance activity for 180 days and then consider options for a permanent rule change.

The penalty for multiple violations also went up as part of the new temporary rule. Two violations in a two-year period would result in an automatic 30-day license suspension. Three violations in a two-year period would result in license revocation.

The OLCC already has the authority to suspend or revoke a marijuana worker permit if a permittee violates any applicable laws or rules.

Earlier this month, the OLCC released the results of a decoy operation from December. It found that marijuana shops in areas throughout the state failed a check for prohibiting sales to minors.

In the Portland area, four of seven licensed marijuana shops failed the inspection.
