Sniffing-associated deaths in Denmark.

An account is given of 20 deaths, which occurred in association with sniffing during the period 1959--1978. The annual number of deaths was almost constant during the period. Most of the deaths occurred in males. Ether and trichloroethylene were the predominant toxic substances. The material was divided into two groups. Group A, 14 cases, included real sniffing deaths, the cause of death being poisoning by the substance inhaled. In group B, 6 cases, sniffing was a contributory factor to death: 2 cases of suffocation by obstruction, one case of carbon monoxide poisoning during fire, one case of septicemia/severe anemia caused by bone marrow depression, and one case of bleeding to death from stab wounds inflicted by a sniffer against a non-sniffer. The circumstances before and at the time of death are reported, together with the autopsy and toxicological findings when these were performed.
