The article is about how teenagers use cannabis and how it affects the brain. The use of cannabis increases the amount of gray matter in teenagers, even if it is a joint or two. The study was conducted with 46 kids who had admitted to having exposure to cannabis before the age of 14. There is an increase of gray matter in parts of the brain where cannabinoid receptors are. Most of the gray matter were in the amygdala. The amygdala is the part of the brain that is used to control fear and other emotions. The hippocampus is also involved and the hippocampus focuses on memory. Since the brain is still developing, the brain is supposed to get thinner and not thicker. Since, most people think having a joint or two isn’t a big deal in reality it has an affect on the growing brain.
