In cities, drug transactions often occur in seemingly harmless places with large flow of people and are not easy to arouse suspicion. Here are some common places： ### 1. **Parks and green spaces** -**Reason**: Parks are usually crowded with people and have many hidden corners, such as bushes, behind benches or in the woods. These places make it easy for both parties to the transaction to complete the transaction quickly without being noticed. -**Preventive recommendations**: Strengthen patrols in parks, especially at night and in remote areas. Citizens are encouraged to report suspicious behavior. ### 2. **Public parking lot** -**Reason**: Parking lots are usually dense with vehicles and large mobility of personnel. Both parties to the transaction can enter and leave quickly, and it is not easy to attract attention. -**Preventive recommendations**: Install surveillance cameras and increase security patrols, especially at night. ### 3. **Fast food restaurants and cafes** -**Reason**: There is a large flow of people in these places, and both parties to the transaction can pretend to be ordinary customers and use short-term contact to complete the transaction. -**Preventive recommendations**: Employees should receive training to identify suspicious behaviors and report to management or the police in a timely manner. ### 4. **Internet cafes and game halls** -**Reason**: These places usually have more young people gathering, and the environment is noisy, and transaction behavior is not easy to detect. -**Preventive recommendations**: Strengthen site management and regular inspections to ensure the safety of employees and customers. ### 5. **Subway stations and bus stations** -**Reason**: There is a large flow of people in transportation hubs, and both parties to the transaction can take advantage of the crowded environment to quickly complete the transaction and leave. -**Preventive recommendations**: Increase police patrols, especially during peak hours. Citizens are encouraged to report suspicious behavior. ### 6. **Corridors and underground garages in residential areas** -**Reason**: These places are relatively hidden, especially at night, so both parties to the transaction can avoid surveillance and patrols. -**Preventive recommendations**: Strengthen community security, install monitoring equipment, and encourage residents to participate in community safety maintenance. ### 7. **Around schools and universities** -**Reason**: There are usually more students and young people around the school, and the environment is more open, and transaction behavior is not easy to detect. -**Preventive recommendations**: Strengthen patrols around the school to educate students to identify and stay away from drugs. ### 8. **Nightclubs and bars** -**Reason**: These places are dimly lit, the music is noisy, and the transaction behavior is easily masked. -**Preventive recommendations**: Strengthen site management and regular inspections to ensure the safety of employees and customers. ### 9. **Second-hand and flea markets** -**Reason**: There is a large flow of people in these markets, and both parties to the transaction can pretend to be ordinary customers and use short-term contact to complete the transaction. -**Preventive recommendations**: Strengthen market management and conduct regular inspections to ensure the safety and order of the market. ### 10. **Public toilets** -**Reason**: Public toilets are usually more hidden and have a large flow of people. Both parties to the transaction can quickly complete the transaction and leave. -**Preventive recommendations**: Strengthen patrols of public toilets, especially at night and in remote areas. ### Summary The concealment and mobility of drug trading venues complicate prevention efforts. As citizens, we can jointly maintain the safety of the city by raising vigilance, actively participating in community safety maintenance, and reporting suspicious behaviors in a timely manner. At the same time, the government and law enforcement agencies should also strengthen patrols, install monitoring equipment, and carry out public education activities to raise citizens' awareness of prevention. If you find any suspicious behavior, please contact the local police or relevant law enforcement agencies immediately to contribute to the creation of a non-toxic and safe urban environment.
