In the last decade, there has been an unprecedented growth in the number and diversity of drug services. Needle / syringe exchanges and street agencies now provide services alongside the more traditional drug clinics. Interviews with community samples of 408 heroin users and 150 cocaine users revealed extensive overlap of service use. Only one in ten heroin users were in contact with only one type of agency. A similar overlap was seen with cocaine users. Implications for future planning of services are considered.
