Cannabis users are more likely to feel deceived and alienated by others,
study finds
Cannabis users are more likely to experience negative emotions, particularly
feeling alienated from others, new research reveals.
People who use marijuana are significantly more likely to feel that others
wish them harm or are deceiving them, a US study found.
Brain scans also reveal the class-B drug increases signal connectivity in
regions of the brain that have previously been linked to psychosis, the
research adds, which is associated with severe depression.
Teenage cannabis users are particularly affected as their brains are still
developing, according to the researchers.
In the US, 44 percent of those aged 12 or over have used cannabis at some
point in their lives.
How the research was carried out
The researchers, from the National Institute on Alcoholism and Alcohol Abuse
in Bethesda, Maryland, analyzed 60 people, half of which were cannabis
dependent.
The study's participants completed a questionnaire that asked them about
their feelings of stress, aggression, reactivity and alienation.
Brain scans were also taken of all of the participants.
Link between cannabis and mental health
Dr Cameron Carter, editor of the journal Biological Psychiatry: Cognitive
Neuroscience and Neuroimaging, where the study was published, said: 'These
brain imaging data provide a link between changes in brain systems involved
in reward and psychopathology and chronic cannabis abuse, suggesting a
mechanism by which heavy use of this popular drug may lead to depression and
other even more severe forms of mental illness.'
According to study author Dr Peter Manza, measuring brain activity is
relatively easy and non-invasive.
Therefore, the procedure used in the investigation could be carried out to
monitor cannabis users' mental health risks.
This comes after researchers from Warwick Medical School discovered in
December last year teenage cannabis use may increase a person's risk of
suffering from bipolar disorder in later life.
People who used cannabis at least two-to-three times a week at 17 years old
are more likely to experience hypomania in their earlier 20s, according to
the first study of its kind.
