The Tokyo Metropolitan Police Department held an emergency meeting with cab and trucking companies Friday to address accidents caused by drivers under the influence of "dappo" (loophole) drugs.

According to the MPD, five organizations, including the Tokyo Trucking Association and the Tokyo Hire-Taxi Association, attended the conference to discuss ways of preventing crimes related to the quasi-legal drugs, which the government officially terms as "dangerous drugs."

During Friday's meeting, the MPD briefed the industry groups on the dangers posed by dappo drugs and asked attendees to make their drivers aware of them.
