Cannabis et distorsions cognitive

[daniel]

[traduction Raph]

Une étude non-clinique, basée sur un large échantillon d'étudiants (189),
suggère que les usagers réguliers de cannabis sont significativement plus
enclins à présenter des distorsions cognitive et de perception telles que
le désordre, mais pas de déficience interpersonnelle, que les usagers
non-réguliers et ceux qui n'en ont jamais consommé. De plus, le début des
symptômes schizotypiques précède généralement le début d'utilisation de
cannabis. Les découvertes ne soutiennent pas de relation causale entre
l'utilisation de cannabis et les traits schizotypiques.

The current investigation uses a large non-clinical sample of undergraduate
college students (N=189) to investigate schizotypal traits among cannabis
and non-cannabis users, as well as the temporal order of the onset of these
traits and cannabis use. Findings suggest that regular cannabis users are
significantly more prone to cognitive and perceptual distortions as well as
disorganization, but not interpersonal deficits, than non-regular users and
those who have never used. Additionally, the onset of schizotypal symptoms
generally precedes the onset of cannabis use. The findings do not support a
causal link between cannabis use and schizotypal traits.
