Quotes and Notes: This article describes the effects of marijuana use and how it can have a negative impact on the development of the teenager’s brains judgement, critical thinking and memory processes. (Lisdahl) Krista Lisdahl, director of brain imaging and neuropsychology lab at University of Wisconsin, Milwaukee, states that a child’s brain is larger and during the teenage years the brain connections that were not being used are eliminated and the brain becomes “faster and more efficient” (Lisdahl). Krista Lisdahl reports students that regularly use marijuana has an average of one point grade lower than non-using students.
A Duke University study showed that regular use of marijuana starting during the teenage years and was continued for many years lost about eight IQ points from childhood to adulthood. The younger they were when they started using marijuana the higher the IQ decline. They also found that they did worse in tests of memory and decision-making than adults who hadn't smoked pot. Also, discussed in this study was that the higher decline in IQ, decision making, and memory testing results of the studies were among heavy marijuana users and there may be variables that cause of the heavy use such as subtle emotional differences, and cognitive functioning differences.
