| Ø      The infrastructure of national
  knowledge about the trends and circumstances of cannabis use is fundamentally
  weak and desperately needs strengthening. âØ           
  The epidemiological
  data available indicates that close to 30% of the population (12 to 64 years
  old) has used cannabis at least once.
 âØ           
  Approximately 10%
  used cannabis during the previous year.
 âØ           
  Up to 30% of those
  who used cannabis in the last year are current users (have used cannabis this
  month).
 Ø      Approximately 15% of current users
  would be daily users âØ           
  Use is highest
  between the ages of 16 and 24.
 âØ           
  The prevalence of use
  during the current year is highest, approximately 40%, in young people of
  high school age.
 âØ           
  The prevalence of
  monthly use in young people is approximately 30%.
 âØ           
  The prevalence of
  daily use in young people is approximately 9%.
    Ø      The average age of introduction to
  cannabis is 15. âØ           
  Most experimenters
  stop using cannabis.
 âØ           
  Regular users were
  generally introduced to cannabis at a younger age.
 âØ           
  Long-term users most
  often have a trajectory in which use 
  rises and falls.
 âØ           
  Long-term regular
  users experience a period of heavy use in their early 20s.
 âØ           
  Most long-term users
  integrate their use into their family, social and occupational activities.
    âØ           
  Cannabis itself is
  not a cause of other drug use.
 âØ           
  Cannabis use can be a
  gateway because it is illegal, which puts users in contact with other
  substances.
 â
 âØ           
  Cannabis itself is
  not a cause of delinquency and crime.
 âØ           
  Young people with a
  trajectory of regular and heavy use are often already on a deviant if not
  delinquent trajectory.
 Ø      Cannabis is not a cause of
  violence. |
