Cannabis use, particularly tetrahydrocannabinol (THC), has raised concerns about its effects on the adolescent brain. A recent study conducted at the University of Montreal reveals that THC, the main psychoactive component of cannabis, could contribute to the shrinking of the cerebral cortex.
This discovery comes at a time when cannabis use is becoming increasingly widespread. In the United Kingdom, nearly one in ten people report having used cannabis in the past year. This rate rises to 15% among young people aged 16 to 24.
Warnings are also being issued regarding the harmful effects of cannabis in the long term. In the United States, where cannabis is legalized in 24 states, an increase in serious side effects linked to chronic use has been observed. Among these effects, “scromiting”, an alarming condition characterized by simultaneous screaming and vomiting attacks, has been particularly highlighted.
Previous studies have already highlighted the risks associated with early cannabis use. Research from 2007 showed that adolescents who smoked cannabis at least five times had a twice-high risk of developing serious psychotic disorders in the following decade compared to non-users.
Dr. Tomas Paus, psychologist and co-author of the study from the University of Montreal, warns about the potential consequences of cannabis on the brain. He points out that cannabis use could harm the brain’s ability to learn, interact with others and manage new experiences.
In conclusion, it is important to raise awareness about the risks associated with cannabis use, particularly among adolescents. The scientific data highlighting the harmful impacts of THC on the cerebral cortex underscore the importance of promoting a responsible attitude towards this substance to protect the mental health and well-being of individuals, particularly the younger generations.
