In order to assess the impact of changes in the Licensing Laws in England, a prospective study was undertaken of patients attending the Accident and Emergency Department of the Newcastle General Hospital. Patients were breathalysed in October 1986, before the liberalisation of the Licensing Laws in England and Wales and again in October 1988, after this change. A blood alcohol level of greater than 50 mg/100 ml was detected in 13% of all attenders in 1986 and 14% in 1988. A comparison of the two years revealed no significant change in the number of patients who had ingested alcohol prior to attendance, although there was a trend towards increased frequency of alcohol ingestion in nighttime attenders.
