ABSTRACT	
  
This	
  analysis	
  uses	
  data	
  from	
  a	
  
follow-­‐up	
  study	
  of	
  birth	
  cohorts	
  
(born	
  1959-­‐1966)	
  at	
  age	
  40-­‐49	
  
years.	
  More	
  than	
  half	
  of	
  the	
  
parDcipants	
  reported	
  having	
  used	
  
cocaine.	
  	
  There	
  were	
  significant	
  
differences	
  between	
  men	
  and	
  
women	
  (60%	
  in	
  men	
  versus	
  45%	
  in	
  
women,	
  p=.006),	
  but	
  not	
  by	
  
educaDon.	
  	
  
RESULTS	
  
Among	
  all	
  parDcipants	
  across	
  both	
  
sites,	
  more	
  than	
  half	
  (53%)	
  reported	
  
having	
  used	
  cocaine	
  at	
  some	
  point	
  in	
  
their	
  life.	
  	
  A	
  higher	
  percentage	
  of	
  
men	
  (60%)	
  than	
  women	
  (45%)	
  
reported	
  having	
  used	
  cocaine	
  (P=.
006).	
  People	
  with	
  a	
  high	
  school	
  
degree	
  or	
  less	
  were	
  slightly	
  more	
  
likely	
  to	
  have	
  used	
  cocaine	
  (57%)	
  
than	
  those	
  with	
  higher	
  educaDon	
  
(52%),	
  but	
  the	
  difference	
  was	
  not	
  
staDsDcally	
  significant	
  (P=.501).	
  
CONCLUSION	
  
In	
  this	
  populaDon-­‐based	
  sample,	
  
the	
  majority	
  of	
  people	
  in	
  their	
  40s	
  
reported	
  “ever	
  using”	
  cocaine	
  at	
  
some	
  point	
  in	
  their	
  life.	
  Men	
  were	
  
more	
  likely	
  to	
  have	
  used	
  cocaine	
  
than	
  women	
  (60%	
  vs.	
  45%).	
  	
  Since	
  
these	
  results	
  are	
  based	
  on	
  
retrospecDve	
  recall	
  over	
  a	
  long	
  
period,	
  they	
  are	
  likely	
  to	
  be	
  
underesDmates.	
  	
  Therefore	
  this	
  
study	
  suggests	
  that	
  within	
  the	
  
generaDon	
  born	
  1959-­‐1966,	
  the	
  
majority	
  have	
  some	
  experience	
  
with	
  cocaine	
  use.

RESEARCH	
  METHODS	
  
The	
  330	
  parDcipants	
  in	
  this	
  report	
  were	
  drawn	
  from	
  two	
  comparable	
  birth	
  
cohort	
  studies.	
  	
  The	
  majority	
  were	
  sibling	
  pairs,	
  because	
  the	
  study	
  was	
  
designed	
  to	
  make	
  comparisons	
  within	
  as	
  well	
  as	
  across	
  families.	
  	
  All	
  the	
  
parDcipants	
  were	
  born	
  1959-­‐1966	
  and	
  age	
  40-­‐49	
  at	
  the	
  Dme	
  of	
  the	
  follow-­‐up	
  
interview.	
  	
  They	
  were	
  administered	
  3	
  hour	
  quesDonnaires	
  that	
  included	
  
quesDons	
  on	
  drug	
  use.	
  	
  This	
  report	
  excludes	
  27	
  parDcipants	
  with	
  missing	
  data	
  
on	
  cocaine	
  use	
  and/or	
  educaDon.	
  StaDsDcal	
  comparisons	
  were	
  made	
  using	
  
Fisher	
  exact	
  tests.
