Adolescents who use cannabis frequently may experience a drop in their IQ, according to a new Irish scientific research. The study confirms the harmful neurological and cognitive consequences that frequent cannabis use can have on a young person.
The researchers, led by Dr. Emmet Power of the Department of Psychiatry at RCSI University and the Beaumont Hospital in Dublin, published their findings in the journal Psychological Medicine. previous studies, which involved a total of 808 young people who used cannabis at least once a week for at least six months, as well as - for comparison - 5.308 non-cannabis peers.
Participants, who were monitored until the age of 18, had an IQ test before and after cannabis use. It was estimated that, over time, frequent users had a decrease in IQ of about two points compared to non-users.
"Previous research shows that young people who use cannabis frequently have a worse course in life than their peers and are at greater risk of serious mental illness, such as schizophrenia. "Reducing IQ early in life can have a significant impact on their performance at school and university and later on their career prospects," said RCSI Professor of Psychiatric Epidemiology Mary Canon.
"Cannabis use at a young age is a source of great concern, as the developing brain can be particularly vulnerable to damage at this time. "The findings of the new study help us understand this important public health issue."
