title: Trajectories of Aging Long-Term Mexican American Heroin Injectors: The "Maturing Out" Paradox.
abstract: OBJECTIVE
  To examine the applicability of the "maturing out" theory to a sample of aging Mexican American men who are long-term heroin injectors.
  
  
  METHODS
  Ethnographic data were collected as part of a cross-sectional study of aging Mexican American heroin users in Houston with 20 current heroin users.
  
  
  RESULTS
  Findings indicate that dysfunctions that emerge in the heroin lifestyle lead not to cessation but rather to "maturing in," a specific process of social readjustment that returns the heroin user to a stable maintenance pattern of use instead of a recovery phase. This process of paradoxical maturing out can be attributed to the unconditional social support provided to the heroin user by family, peers, and the tecato subculture embedded in Mexican American communities.
  
  
  CONCLUSIONS
  Results highlight the implications for the intersection of heroin-related conditions, natural age-related impairments, and cognitive functioning that make this population increasingly susceptible to adverse health consequences.
