Background Cocaine intoxication can lead to fatal cardiovascularand cerebrovascular events. In addition, the neurobehavioraleffects of cocaine may increase the likelihood that a user willreceive violent fatal injuries. Since New York City is a centerfor the importation and distribution of cocaine, we sought todetermine the extent of cocaine use among city residents withfatal injuries.
Methods Among a total of 14,843 residents of New York City whoreceived fatal injuries from 1990 through 1992, we determinedthe proportion who had used cocaine shortly before their deaths.We also determined the population-based rates of fatal injuriesthat were known to follow cocaine use and the proportion ofall deaths of New York City residents that was represented bythese cases for each demographic stratum. For people 15 to 44years of age, fatal injury after cocaine use was ranked withother causes of death as though it was a separate cause.
Results Cocaine use, as measured by the detection of the metabolitebenzoylecgonine in urine or blood, was found in 26.7 percentof all New York City residents receiving fatal injuries; freecocaine was detected in 18.3 percent. Approximately one thirdof deaths after cocaine use were the result of drug intoxication,but two thirds involved traumatic injuries resulting from homicides,suicides, traffic accidents, and falls. If fatal injury aftercocaine use was considered as a separate cause of death, itwould rank among the five leading causes of death among those15 to 44 years of age in New York City.
Conclusions Fatal injuries among cocaine users account for asubstantial proportion of all deaths among young adults in NewYork City.
