The first thing to report should be facts, not subjective assumptions, that is to say, the informant should be responsible for the authenticity of the reported content. For drug abuse, the informant can report as long as he/she sees others taking drugs or is preparing to take drugs. Several ways to report drug abuse:
 1. For telephone reporting, the informant may call 110 or the reporting telephone number published by the public security organs at all levels.
 2. When reporting a visit, the informant can directly report to the public security organs at all levels.
 3. In case of letter reporting, the informant can write a letter and mail it to the drug control department of the public security organs at all levels of the province.
 4. In other ways, the informant can report to the public security organs at all levels by email, SMS, WeChat and other means. Public security organs at all levels throughout the province will strictly keep secrets for informants to ensure their personal and property safety.
