| Ø      The expression
  drug addiction should no longer be used and we should talk instead of
  substance abuse and dependency.  Ø      Between 5% and
  10% of regular cannabis users are at risk of developing a dependency.  Ø      Physical
  dependency on cannabis is virtually non-existent.  Ø      Psychological
  dependency is moderate and is certainly 
  lower than that for nicotine or alcohol.  Ø      Most regular
  users of cannabis are able to diverge from a trajectory of dependency without
  requiring treatment.  Ø      There are many
  forms of treatment but nothing is known about the effectiveness of the different
  forms of treatment for cannabis dependency specifically.  Ø      As a rule,
  treatment is more effective and less costly than a prison sentence.  Ø      Studies of the
  treatment programs should be conducted, including treatments programs for
  people with cannabis dependency.  Ø      Studies should
  be conducted of the interaction between the cannabinoid system and the opioid
  system.  |
