  This  paper  examines  the  research  evidence on the question of whether
sustained  use  of  marijuana  may  produce  chronic cerebral impairment as
measured  by  neuropsychological  measures. Evidence from both American and
cross-cultural  studies  suggests  that marijuana probably does not produce
chronic  cerebral  impairment,  although  subtle impairment cannot be ruled
out.  Several suggestions for new lines of research are discussed including
prospective  studies, effects of cannabis use on later aging processes, and
true experimental studies.  (38 Refs.)

  This  paper  examines  the  research  evidence  relating sustained use of
marijuana  to  chronic cerebral impairment. Evidence from both American and
cross-cultural   studies   is  reviewed,  with  a  particular  emphasis  on
methodological  problems  in  the  research.  The focus of this paper is on
neurological  findings  while  another  paper focuses on neuropsychological
findings.  On  the basis of available research, it was concluded that there
is  no  evidence  that marijuana produces gross structural cerebral changes
and little evidence that it leads to functional impairment, although subtle
impairment cannot be ruled out.  (93 Refs.)
