The study has examined the effect that cannabis has on teens if they smoke it every week.
At the end of the study, the University of Maryland School of Medicine came to the conclusion that people who smoke cannabis every week during their adolescent years are more likely to develop conditions such as attention deficit disorder (ADD) and schizophrenia, and are also more likely to suffer permanent reductions in intelligence.
The study specifically examined people between the ages of 13 and 15 years old. However, the study used mice, and exposed them to low levels of marijuana for a period of 20 days, according to the Independent. The study found that the problems that occurred in the mice during the adolescence period were also found to continue into their adult lives, due to the fact that they pinpoint ‘cortical oscillations’ in the brain.
These oscillations are a main part of cognitive processes that develop during the early teenage years, which means that weed smokers will stunt the development of them which will them damage them for years to come, according to the report. The researchers at the University of Maryland School of Medicine then did the same test on older mice, but got different results, meaning that the initial effects of smoking weed were specific effects that occur on more immature brains.
