ABSTRACT
Using the method of sewage epidemiology, the occurrence characteristics and changes of two typical psychoactive drugs methamphetamine and ketamine in the domestic sewage of a city in Guangdong Province during and before and after the new crown epidemic in 2020 were studied, and the mobile phone signaling data was used to analyze The total population, structural characteristics and their change laws were combined to analyze the changes in the consumption of the two drugs during the epidemic and before and after the epidemic. The results show that the actual population of the city during the epidemic decreased by about 45% compared with before the epidemic. The total consumption of various drugs has dropped by about 75% compared to before the epidemic. The significant decline in total consumption was largely caused by the actual population decline during the epidemic. In fact, the per capita consumption levels of methamphetamine and ketamine in the city during the epidemic Compared with the pre-epidemic drop of less than 50%. Taking into account the strict control measures during the epidemic, this decline shows that the abuse of these two psychotropic substances is extremely stubborn;after the epidemic, the consumption of the two drugs and their concentrations in the environment have increased significantly. It has basically returned to the level before the epidemic, which further proves the stubbornness of psychotropic substance abuse.
