Conhecimentos produzidos acerca do crack: uma incurs？o nas disserta？？es e teses brasileiras

this is a systematic review based on the integrative review method, which sought to analyze the characteristics of knowledge produced by studies on crack, in brazilian master's and doctoral courses. the investigation comprised 33 studies (18 dissertations and 15 theses). among them, 51.5% were from the health science area with emphasis on the postgraduate program in psychiatry (and medical psychology), which provided five dissertations/theses. most of the knowledge on the epidemic (51.5%) are from the universidade federal de s？o paulo and universidade de s？o paulo, with the largest number of studies (81.8%) concentrated in the southeast. the themes most analyzed were: organic alterations, drug trafficking and crack use, hiv/aids, types and strategies of treatment. the results showed that brazilian stricto sensu knowledge about crack is still incipient, sketchy and ineffectual, albeit promising due to demands and implications that this epidemic imposes upon society.
