An epidemiological study on alcohol/drugs related fatal traffic crash cases of deceased drivers in Hong Kong between 1996 and 2000.
This study is designed to evaluate the correlation between fatal vehicle crashes (FVC) and consumption of alcohol and/or drugs among drivers. Between 1996 and 2000 in Hong Kong, a total of 197 FVC cases of deceased drivers were investigated. The blood and/or urine samples of the victims were examined for the presence of alcohol and drugs. The 197 cases were then classified into two groups: single-vehicle crashes (SVC) and multiple-vehicle crashes (MVC). Out of the 106 cases for the latter group, alcohol and/or drugs were detected in 22 cases (21%) while the remaining 84 cases (79%) were regarded as no significant finding. As for the 91 cases in SVC group, 51 cases (56%) were positive for alcohol and/or drugs. The findings indicate that a driver consuming alcohol and/or drugs has a higher risk of being involved in a FVC. The most frequently detected drugs for SVC group (11 cases) were: 46% central nervous system (CNS) stimulants (including designer drugs like MDMA); 36% cannabis; 18% benzodiazepines and 9% ketamine. The detected drug for the only case in the MVC group was a CNS stimulant. The number of cases with ketamine, methamphetamine and MDMA detected has increased in recent years as these party drugs have gained popularity in Hong Kong.
