***Science: Schizophrenia
Israelian scientists propose that the association between
cannabis use and increased risk for schizophrenia that have been
observed in recent studies from Sweden, the Netherlands, New
Zealand, and Israel may not be causal. Several studies have
reported an association between genes encoding the
cannabinoid receptor and
schizophrenia. The researchers write: "An alternative explanation
of the association between cannabis use and schizophrenia might
be that pathology of the cannabinoid system in schizophrenia
patients is associated with both increased rates of cannabis use
and increased risk for schizophrenia, without cannabis being a
causal factor for schizophrenia." (Source: Weiser M, Noy S.
