Cocaine, even in small amounts, can be fatal when taken in warm environments, such as hot weather, crowded nightclubs or rave parties – all-night dance parties where illicit cocaine use is common – according to researchers at UT Southwestern Medical Center at Dallas.
The researchers discovered that cocaine elevates body temperature by impairing the body’s ability to increase skin-blood flow, to sweat and to perceive excessive heat stress. The findings appear in today’s issue of Annals of Internal Medicine.
“Individuals who abuse cocaine, especially in hot temperatures while participating in recreational sports or attending rave parties, won’t perceive that they are hot and are, therefore, less likely to drink water or to find cooler conditions,” said Dr. Craig Crandall, assistant professor of internal medicine and lead author of the study.
“The hyperthermic effects of cocaine are greatly amplified when the drug is used under these conditions. “This may result in serious heat-related injuries, including heat cramps, heat exhaustion, heat stroke and ultimately death,” added Crandall, who is also a research scientist at the Institute for Exercise and Environmental Medicine, a joint venture between UT Southwestern and Presbyterian Hospital of Dallas.
