May I ask about the channel for the public to report drug-abusing? Is there a telephone number that people can use if they find someone using drugs, for example?

Not at all.

Thank you for your kind introduction.

Yes. 186186 is the number to the anti-drug telephone inquiry service of ND. People can call this number to enquire about drug abuse problems or related information, having regard to individual needs, seek immediate counseling, or referral for treatment services from social workers.
