Family First Comment: More reasons not to legalise.
Just one or two joints is enough to change the structure of a teenager’s brain, scientists have warned.
And the drug could cause changes affecting how likely they are to suffer from anxiety or panic, according to a study.
Researchers found 14-year-old girls and boys exposed to THC – the psychoactive chemical in cannabis – had a greater volume of grey matter in their brains.
This means the tissue in certain areas is thicker, and it was found to be in the same areas as the receptors which marijuana affects.
Experts said thickening of brain tissue is the opposite of what usually happens during puberty, when teenagers’ brain matter gets thinner and more refined.
Researchers from the University of Vermont scanned the brains of teenagers from England, Ireland, France and Germany to study marijuana’s effects.
They found differences in the volume of grey matter in the amygdala and the hippocampus.
These sections are involved with emotions, fear, memory development and spatial skills – changes to them suggests smoking cannabis could affect these faculties.
