The presence or absence of support from other people was one of the topics included in semi-structured interviews carried out with close relatives of people with alcohol or other drug problems in Mexico and England. Of the full set of interviews, matched sub-samples of twelve reports from each country were analysed qualitatively. Examples of the support received, or lacked, by two relatives are first presented in some detail. The main sub-categories of support, or its lack, described in the twenty-four reports are then presented. Finally a preliminary comparison of data from the two countries is also reported. As well as providing a detailed picture of types of support (e.g. emotional, material) that are familiar from studies with other populations, this paper also emphasizes the importance of the close relative's perception of the relationship between the alcohol or drug user and the supportive or unsupport-ive 'other', and describes a range of circumstances under which relatives are denied support. Preliminary support is obtained for the hypothesis that Mexican social networks would be more dominated by kin and neighbours, whilst English relatives would draw for support upon more diverse networks.
