The answer to this depends on the person and how their body can process the marijuana. There are a few other factors that affect the answer to this question, such as dosage, type of strain of marijuana, and, again, the kind of person someone is. Many different answers vary by person, but studies from the NIH National Library of Medicine states that students who used marijuana more frequently during the first year of college tended to skip more of their classes, which, in turn, contributed to their tendency to earn lower grades. Although marijuana is sometimes frowned upon, there are still some potential benefits that come with its use. These benefits include reduced anxiety, increased focus, and expanded creativity. In my opinion, there is no definitive answer to this question because you can find facts and other sources to back up what you have to say in both circumstances of the question.
