The advice and services provided by community pharmacies are viewed by policy makers as having an increasingly important contribution to make as a primary health care resource to local populations. However, little attention has been given to the variations which may exist between pharmacies operating in different localities. Findings from an ethnographic study of pharmacies illuminate differences in the nature and quality of advice and services provided by pharmacies operating in disparate localities. Analysis of qualitative data suggests that differences in the environment within which pharmacies are located and organised influence the type of service provided to local populations. The possibility of an inverse care law operating in relation to the nature of services in poor urban localities compared to those in rural areas is also discussed.
