Five cases of poisoning by barbiturates were recorded in 1955 and 193 in 1964.Urine and blood samples from persons charged with driving motor vehicles while under the influence of drugs were also examined. In 1958 only one such case was reported to the Laboratory, whereas 25 cases were recorded in 1964; barbiturates were detected in 18 of these 25. Patients must be warned of the risks of ingesting alcohol while receiving barbiturate treatment.
